SE 84LV

LOW TEMPERATURE CURE EPOXY PREPREG

Versatile, high-strength prepreg system
Curable at temperatures as low as 80 C (176 F)
Can be processed with vacuum-only processing
Excellent tack
Low Viscosity Ideal for use with heavy fibre weights
Lloyd s Register and DNV-GL Certified Formats Available

INTRODUCTION
SE 84LV is an exceptionally versatile hot-melt, epoxy prepreg. It can be cured at temperature as low as 80 C (176 F), or
can be used for faster moulding of components at 120 C (248 F). This is achieved with an extremely good outlife of up to 8
weeks at 18-22 C (64-72 F). It is a toughened system, and offers excellent mechanical properties on a wide variety of
reinforcing fabrics and fibres.
SE 84LV is commonly used in vacuum bagging, press-moulding, autoclave
and other pressure moulding processes.
SE 84LV is a very low viscosity system used with heavy fibre weights where
low-flow processing conditions (vacuum bag pressure and minimum cure
temperature), are likely to be used. With its high compressive strength it is
widely used in large heavily loaded components, such as yacht hulls, and
spars. It has been selected for use by various America s Cup syndicates and
boats racing in the Volvo Ocean Race.
SE 84LV is widely used in sandwich structures with honeycomb, foam and
balsa cores, primarily with the toughened SA 80 Adhesive Film.

PROCESSING NOTES – GENERAL

PROCESSING NOTES – CURING
PREPARATION
When preparing the lay-up the prepreg should be removed from the
freezer and allowed to thaw in a sealed bag. This may take 6 to 24
hours depending on roll size. This prevents atmospheric moisture
from condensing on the prepreg which may cause voiding on cure.
The mould surface should be release coated and must have been
tested for vacuum integrity prior to lay-up.
LAYING-UP
The following procedure is recommended for preparing vacuum
cured laminates.

1. Place the lay-up on a tool or caul sheet which has been treated
with a release agent or film. Insert a thermocouple into the lay-up
near the centre ply of the thickest edge section, outside the net trim
line. A separate prepreg nylon peel ply is available for covering a
mould tool prior to lay-up in order to leave a clean, textured surface
for subsequent bonding.

2. Apply a peel ply to the surface of the lay-up. Note that for good
secondary bonding of a peel-plied surface of an SE 84LV prepreg
laminate, a nylon peel ply, such as Gurit s Stitch Ply A, is strongly
recommended. This is particularly important where the cure
temperatures are in excess of 90 C (194 F). Cover the peel ply
entirely with a perforated release film. Normally, no edge resin
bleeder system is used. For thin sections, Gurit WL3600P90 grade
release film are recommended, while for sections of 4mm and
above, Gurit WL3600P release film is also suitable. With WL3600P
the amount of resin bled away is controlled by the number of dry
plies of resin bleeder cloth placed over the perforated release film.

3. Install a vacuum bag by standard techniques. Insert at least two
vacuum stems through the bag connecting one to the vacuum
source and the other, at a point on the part furthest from the source,
to a calibrated vacuum gauge. Position part in the oven or autoclave
and draw vacuum to check for bag or system leaks.

4. Commence the heat-up cycle, typically between 0.3 C(0.5 F)/min
and 2 C(3.6 F)/min to the final cure temperature. At 85 C (185 F),
the temperature should be held up for 10 hours. Faster cures may
be obtained at elevated temperatures, e.g. 6 hours at 90 C (194 F),
3 hours at 100 C (212 F) or 1 hour at 120 C (248 F). All
temperatures measured by the previously installed thermocouple.
When curing at 80 C (176 F) a minimum of 12 hours is
recommended. Vacuum should be maintained as high as possible,
with a minimum of 85% throughout the cure cycle.

5. Upon completion of cure, turn off heat and cool until part
temperature has fallen below 60 C (140 F). When fully cooled, the
part may be debagged, trimmed and machined as necessary. A
post-cure is not required.

CURE CYCLES
For a good balance of composite properties, it is
recommended that the laminate is cured at 80 C (176 F) for a
minimum of 12 hours. A laminate may be cured in two stages –
if, for example, making a cored component. However in a two
stage cure, a minimum of 4 hours at 85 C (185 F) or 5 hours at
80 C (176 F) is recommended before debagging a skin, and it
must be ensured that this skin is cured for the equivalent of at
least 10 hours at 85 C (185 F) or 12 hours at 80 C (176 F)
before going into service.

SE 84LV may be cured at higher temperatures for a shorter
time. At a cure temperature of 100 C (212 F) cure can be
achieved in 3 hours or at 120 C (250 F) cure can be achieved
in 1 hour.

It is not recommended to cure SE 84LV under vacuum
pressures of less than 85%. If a ramp rate of less than
0.3 C/min (0.5 F/min) is used, users should satisfy themselves
that this allows adequate flow.

CURING AT 80 C (176 F)
When curing at 80 C (176 F) it is important to ensure the
temperature is monitored off the trailing thermocouple. 80 C
(176 F) should be treated as the minimum cure temperature
for SE 84LV; 70-75 C (158-167 F) will not generate adequate
mechanical properties.

THIN LAMINATES
When using very thin laminates (e.g. with a total laminate fibre
weight of less than 300gm
2
), care needs to be taken to avoid
extracting excessive amounts of resin during the cure process.
To avoid this, a microporous release film can be used, and for
particularly critical components, a prepreg peel ply should be
used.

CORE BONDING

This product can be used in conjunction with typical core materials. Representative test panels should be made to ensure that the laminate
construction, curing method and other variables allow full filling of any cuts or slits in the foam. The cure cycles given in this datasheet are
for typical monolithic flat panels and may not be appropriate for sandwich panels.
When using Nomex or aluminium honeycombs, the separate SA 80 adhesive film is recommended and full details of use are provided on
the separate SA 80 data sheet. This adhesive film is supplied on a lightweight glass carrier, or in some cases it can be supplied directly
coated onto one face of the SE 84LV prepreg.
The system is fully compatible with Ampreg wet layup epoxy systems and therefore all types of cores may be bonded to a first skin by
using a separate wet-bonding operation. In this case, the addition of filler powders to the appropriate resin system is required to provide
the correct paste-like consistency.

All prepreg materials should be stored in a freezer when not in
use to maximise their useable life, since the low temperature
reduces the reaction of resin and catalyst to virtually zero.
However, even at -18 C (0 F), the temperature of most
freezers, some reaction will still occur. In most cases after
some years, the material will become unworkable.
When not in use SE 84LV products should be maintained at
-18 C (0 F). To avoid contamination on their surfaces, allow
rolls to reach room temperature before unwrapping.

INTRODUCTION
SE 75 is an extremely versatile hot melt epoxy prepreg system. It builds on the established good handling and performance of SE
84LV but has more versatile cure possibilities from 12 hours at 70 C (158 F) to 45 minutes at 120 C (248 F), whilst maintaining
an 8 week shelf life at 18-22 C. This flexibility combined with its exceptional mechanical and thermal performance makes it suitable
for a wide range of marine and industrial applications.

TYPICAL END USE APPLICATIONS
SE 75 can be used for any high-performance structure. Its long shelf life at 18-22 C means it is particularly suited to large
components that need to remain in mould for long durations prior to curing.

SE75-10-0223 2

INSTRUCTIONS FOR USE
PREPARATION
When preparing the lay-up the prepreg should be removed from
the freezer and allowed to thaw in a sealed bag. This may take 6
to 24 hours depending on roll size. This prevents atmospheric
moisture from condensing on the prepreg which may cause
voiding on cure. The mould surface should be release coated and
must have been tested for vacuum integrity prior to lay-up.
LAYING-UP
The following procedure is recommended for preparing out of
autoclave vacuum cured laminates.

1. Place the lay-up on a tool which has been treated with a high
temperature release agent or film. Insert a thermocouple into the
lay-up near the centre ply of the thickest edge section, outside the
net trim line.

2. Apply a peel ply to the surface of the lay-up if required, a heat
scoured nylon peel ply is strongly recommended. For thin
laminates a prepreg peel ply should be considered to prevent over
bleed of resin. Cover the peel ply entirely with a low bleed
perforated release film. Typically a minimum of 150g/m breather
fabric should be used to control the resin bleed and air flow.

3. Install a vacuum bag. Position part in the oven or autoclave and
draw vacuum to check for bag or system leaks.

4. It is not recommended to cure SE 75 under vacuum pressures
of less than 85%.

5. Cure as described in the following section

6. Upon completion of cure, turn off heat and cool until part
temperature has fallen below 60 C (140 F). When fully cooled,
the part may be debagged, trimmed and machined as necessary.
A post-cure is not required.

CORE BONDING
This product can be used in conjunction with typical core
materials. Representative test panels should be made to ensure
that the laminate construction, curing method and other variables
allow full filling of any cuts or slits in the foam. The cure cycles
given in this datasheet are for typical monolithic flat panels and
may not be appropriate for sandwich panels.
When using Nomex or aluminium honeycombs, the separate
SA75-90 adhesive film is recommended and full details of use are
provided on the product data sheet. This adhesive film can be
supplied with or without lightweight glass carrier, or in some cases
it can be supplied directly coated onto one face of the SE 75
prepreg.

The system is fully compatible with Ampreg wet layup epoxy
systems and therefore all types of cores may be bonded to a first
skin by using a separate wet-bonding operation. In this case, the
addition of filler powders to the appropriate resin system is
required to provide the correct paste-like consistency.

THIN LAMINATES
When using very thin laminates (e.g. with a total laminate fibre
weight of less than 300-400gm
2
), care needs to be taken to avoid
extracting excessive amounts of resin during the cure process. To
avoid this, a microporous release film can be used, and for
particularly critical components, a prepreg peel ply should be used.

CURE CYCLE
Commence the heat-up cycle, between 0.3 C (0.5 F)/min and 2 C
(3.6 F)/min to the final cure temperature. At 70 C (158 F), the
temperature should be held for 12 hours. Faster cures are obtained
at elevated temperatures, e.g. 6 hours at 80 C (176 F), 45 minutes
at 120 C (248 F). All temperatures measured by thermocouple
installed on the laminate surface. Vacuum should be maintained as
high as possible throughout the cure cycle.

If a ramp rate of less than 0.3 C/min (0.5 F/min) is used, users
should satisfy themselves that this allows adequate resin flow.
CURING AT 70 C (158 F)
When curing at 70 C (158 F) it is important to ensure the
temperature is monitored from the lowest thermocouple reading in
the laminate. 70 C (158 F) should be treated as the minimum cure
temperature for SE75; 65-70 C (149-158 F) will not generate
adequate mechanical properties.

To maximise the de-frosted shelf life of the material it is beneficial
to maintain a cool working environment
All prepreg materials should be stored in a freezer when not in use
to maximise their useable life, since the low temperature reduces
the reaction of resin and catalyst to virtually zero. However, even
at -18 C (0 F) the temperature of most freezers, the material will
eventually become unworkable.
When not in use SE 75 products should be maintained at -18 C
(0 F). To avoid condensation allow the rolls to reach room
temperature before removing the plastic wrapping.

INTRODUCTION
SE 75 is an extremely versatile hot melt epoxy prepreg system. It builds on the established good handling and performance of SE
84LV but has more versatile cure possibilities from 12 hours at 70 C (158 F) to 45 minutes at 120 C (248 F), whilst maintaining
an 8 week shelf life at 18-22 C. This flexibility combined with its exceptional mechanical and thermal performance makes it suitable
for a wide range of marine and industrial applications.

TYPICAL END USE APPLICATIONS
SE 75 can be used for any high-performance structure. Its long shelf life at 18-22 C means it is particularly suited to large
components that need to remain in mould for long durations prior to curing.

SE75-08-0422 2

INSTRUCTIONS FOR USE
PREPARATION
When preparing the lay-up the prepreg should be removed from
the freezer and allowed to thaw in a sealed bag. This may take 6
to 24 hours depending on roll size. This prevents atmospheric
moisture from condensing on the prepreg which may cause
voiding on cure. The mould surface should be release coated and
must have been tested for vacuum integrity prior to lay-up.
LAYING-UP
The following procedure is recommended for preparing out of
autoclave vacuum cured laminates.

1. Place the lay-up on a tool which has been treated with a high
temperature release agent or film. Insert a thermocouple into the
lay-up near the centre ply of the thickest edge section, outside the
net trim line.

2. Apply a peel ply to the surface of the lay-up if required, a heat
scoured nylon peel ply is strongly recommended. For thin
laminates a prepreg peel ply should be considered to prevent over
bleed of resin. Cover the peel ply entirely with a low bleed
perforated release film. Typically a minimum of 150g/m breather
fabric should be used to control the resin bleed and air flow.

3. Install a vacuum bag. Position part in the oven or autoclave and
draw vacuum to check for bag or system leaks.

4. It is not recommended to cure SE 75 under vacuum pressures
of less than 85%.

5. Cure as described in the following section

6. Upon completion of cure, turn off heat and cool until part
temperature has fallen below 60 C (140 F). When fully cooled,
the part may be debagged, trimmed and machined as necessary.
A post-cure is not required.

CORE BONDING
This product can be used in conjunction with typical core
materials. Representative test panels should be made to ensure
that the laminate construction, curing method and other variables
allow full filling of any cuts or slits in the foam. The cure cycles
given in this datasheet are for typical monolithic flat panels and
may not be appropriate for sandwich panels.
When using Nomex or aluminium honeycombs, the separate
SA75-90 adhesive film is recommended and full details of use are
provided on the product data sheet. This adhesive film can be
supplied with or without lightweight glass carrier, or in some cases
it can be supplied directly coated onto one face of the SE 75
prepreg.

The system is fully compatible with Ampreg wet layup epoxy
systems and therefore all types of cores may be bonded to a first
skin by using a separate wet-bonding operation. In this case, the
addition of filler powders to the appropriate resin system is
required to provide the correct paste-like consistency.

THIN LAMINATES
When using very thin laminates (e.g. with a total laminate fibre
weight of less than 300-400gm
2
), care needs to be taken to avoid
extracting excessive amounts of resin during the cure process. To
avoid this, a microporous release film can be used, and for
particularly critical components, a prepreg peel ply should be used.

CURE CYCLE
Commence the heat-up cycle, between 0.3 C (0.5 F)/min and 2 C
(3.6 F)/min to the final cure temperature. At 70 C (158 F), the
temperature should be held for 12 hours. Faster cures are obtained
at elevated temperatures, e.g. 6 hours at 80 C (176 F), 45 minutes
at 120 C (248 F). All temperatures measured by thermocouple
installed on the laminate surface. Vacuum should be maintained as
high as possible throughout the cure cycle.

If a ramp rate of less than 0.3 C/min (0.5 F/min) is used, users
should satisfy themselves that this allows adequate resin flow.
CURING AT 70 C (158 F)
When curing at 70 C (158 F) it is important to ensure the
temperature is monitored from the lowest thermocouple reading in
the laminate. 70 C (158 F) should be treated as the minimum cure
temperature for SE75; 65-70 C (149-158 F) will not generate
adequate mechanical properties.

All prepreg materials should be stored in a freezer when not in use
to maximise their useable life, since the low temperature reduces
the reaction of resin and catalyst to virtually zero. However, even
at -18 C (0 F) the temperature of most freezers, the material will
eventually become unworkable.
When not in use SE 75 products should be maintained at -18 C
(0 F). To avoid condensation allow the rolls to reach room
temperature before removing the plastic wrapping.

SE84LV
High Performance Prepreg System

SE 84LV is an exceptionally versatile hot-melt, epoxy prepreg. It can
be cured at temperature as low as 80 C (176 F), or can be used for
faster moulding of components at 120 C (248 F). This is achieved
with an extremely good outlife of up to 8 weeks at 18-22 C (64-72 F).
It is a toughened system, and offers excellent mechanical properties
on a wide variety of reinforcing fabrics and fibres.
SE 84LV is commonly used in vacuum bagging, press -moulding,
autoclave and other pressure moulding processes.
SE 84LV is a low viscosity system used with heavy fibre weights where
low-flow processing conditions (vacuum bag pressure and minimum cure
temperature), are likely to be used. With its high compressive strength it
is widely used in large heavily loaded components, such as yacht hulls,
and spars. It has been selected for use by various America s Cup
syndicates and boats racing in the IMOCA class.
SE 84LV is widely used in sandwich structures with honeycomb, foam and
balsa cores, primarily with the toughened SA 80 Adhesive Film.

INSTRUCTIONS FOR USE
PREPARATION
When preparing the lay-up the prepreg should be removed from the freezer and allowed to thaw to room temperature in a sealed
bag. This may take 6 to 24 hours depending on roll size. This prevents atmospheric moisture from condensing on the prepreg which
may cause voiding on cure. The mould surface should be release coated and must have been tested for vacuum integrity prior to
lay-up.

LAYING UP
The following procedure is recommended for preparing out of autoclave vacuum cured laminates
1. Place the lay-up on a tool which has been treated with a high temperature release agent or film.
2. Place the lay-up on a tool which has been treated with a high temperature release agent or film. Insert a thermocouple into the
lay-up near the centre ply of the thickest edge section, outside the net trim line.
3. Install a vacuum bag. Position part in the oven or autoclave and draw vacuum to check for bag or system leaks.
4. It is not recommended to cure SE84LV under vacuum pressures of less than 85%.
5. Cure as described in the following section.
6. Upon completion of cure, turn off heat and cool until part temperature has fallen below 50 C (122 F). When fully cooled, the
part may be debagged, trimmed and machined as necessary. A post-cure is generally not required.

CORE BONDING
This product can be used in conjunction with typical core materials. Representative test panels should be made to ensure that the
laminate construction, curing method and other variables allow full filling of any cuts or slits in the foam. The cure cycles given in this
datasheet are for typical monolithic flat panels and may not be appropriate for sandwich panels.
When using Nomex or aluminium honeycombs, the separate SA80 adhesive film is recommended and full details of use are provided
on the product data sheet. This adhesive film can be supplied with or without lightweight glass carrier, or in some cases it can be
supplied directly coated onto one face of the SE84LV prepreg.

THIN LAMINATES
When using very thin laminates (e.g. with a total laminate fibre weight of less than 300-400gm
2
), care needs to be taken to avoid
extracting excessive amounts of resin during the cure process. To avoid this, a very low bleed or microporous release film can be
used, and for particularly critical components, a prepreg peel ply should be used.

HEALTH AND SAFETY
The following points must be considered:
1. Skin contact must be avoided by wearing protective gloves. Gurit recommends the use of disposable nitrile gloves for most
applications. The use of barrier creams is not recommended, but to preserve skin condition a moisturising cream should be
used after washing.
2. If the skin becomes contaminated, then the area must be immediately cleansed. The use of resin-removing cleansers is
recommended. To finish, wash with soap and warm water. The use of solvents on the skin to remove resins etc must be
avoided.
Washing should be part of routine practice:
before eating or drinking
before smoking & vaping
before using the lavatory
after finishing work
3. The inhalation of sanding dust should be avoided and if it settles on the skin then it should be washed off. After more

SE 84LV

LOW TEMPERATURE CURE EPOXY PREPREG

Versatile, high-strength prepreg system
Curable at temperatures as low as 80 C (176 F)
Can be processed with vacuum-only processing
Excellent tack
Low Viscosity Ideal for use with heavy fibre weights
Lloyd s Register and DNV-GL Certified Formats Available

INTRODUCTION
SE 84LV is an exceptionally versatile hot-melt, epoxy prepreg. It can be cured at temperature as low as 80 C (176 F), or
can be used for faster moulding of components at 120 C (248 F). This is achieved with an extremely good outlife of up to 8
weeks at 18-22 C (64-72 F). It is a toughened system, and offers excellent mechanical properties on a wide variety of
reinforcing fabrics and fibres.
SE 84LV is commonly used in vacuum bagging, press-moulding, autoclave
and other pressure moulding processes.
SE 84LV is a very low viscosity system used with heavy fibre weights where
low-flow processing conditions (vacuum bag pressure and minimum cure
temperature), are likely to be used. With its high compressive strength it is
widely used in large heavily loaded components, such as yacht hulls, and
spars. It has been selected for use by various America s Cup syndicates and
boats racing in the Volvo Ocean Race.
SE 84LV is widely used in sandwich structures with honeycomb, foam and
balsa cores, primarily with the toughened SA 80 Adhesive Film.

PDS-SE 84LV-27-0421 2

PROCESSING NOTES – GENERAL

PROCESSING NOTES – CURING
PREPARATION
When preparing the lay-up the prepreg should be removed from the
freezer and allowed to thaw in a sealed bag. This may take 6 to 24
hours depending on roll size. This prevents atmospheric moisture
from condensing on the prepreg which may cause voiding on cure.
The mould surface should be release coated and must have been
tested for vacuum integrity prior to lay-up.
LAYING-UP
The following procedure is recommended for preparing vacuum
cured laminates.

1. Place the lay-up on a tool or caul sheet which has been treated
with a release agent or film. Insert a thermocouple into the lay-up
near the centre ply of the thickest edge section, outside the net trim
line. A separate prepreg nylon peel ply is available for covering a
mould tool prior to lay-up in order to leave a clean, textured surface
for subsequent bonding.

2. Apply a peel ply to the surface of the lay-up. Note that for good
secondary bonding of a peel-plied surface of an SE 84LV prepreg
laminate, a nylon peel ply, such as Gurit s Stitch Ply A, is strongly
recommended. This is particularly important where the cure
temperatures are in excess of 90 C (194 F). Cover the peel ply
entirely with a perforated release film. Normally, no edge resin
bleeder system is used. For thin sections, Gurit WL3600P90 grade
release film are recommended, while for sections of 4mm and
above, Gurit WL3600P release film is also suitable. With WL3600P
the amount of resin bled away is controlled by the number of dry
plies of resin bleeder cloth placed over the perforated release film.

3. Install a vacuum bag by standard techniques. Insert at least two
vacuum stems through the bag connecting one to the vacuum
source and the other, at a point on the part furthest from the source,
to a calibrated vacuum gauge. Position part in the oven or autoclave
and draw vacuum to check for bag or system leaks.

4. Commence the heat-up cycle, typically between 0.3 C(0.5 F)/min
and 2 C(3.6 F)/min to the final cure temperature. At 85 C (185 F),
the temperature should be held up for 10 hours. Faster cures may
be obtained at elevated temperatures, e.g. 6 hours at 90 C (194 F),
3 hours at 100 C (212 F) or 1 hour at 120 C (248 F). All
temperatures measured by the previously installed thermocouple.
When curing at 80 C (176 F) a minimum of 12 hours is
recommended. Vacuum should be maintained as high as possible,
with a minimum of 85% throughout the cure cycle.

5. Upon completion of cure, turn off heat and cool until part
temperature has fallen below 60 C (140 F). When fully cooled, the
part may be debagged, trimmed and machined as necessary. A
post-cure is not required.

CURE CYCLES
For a good balance of composite properties, it is
recommended that the laminate is cured at 80 C (176 F) for a
minimum of 12 hours. A laminate may be cured in two stages –
if, for example, making a cored component. However in a two
stage cure, a minimum of 4 hours at 85 C (185 F) or 5 hours at
80 C (176 F) is recommended before debagging a skin, and it
must be ensured that this skin is cured for the equivalent of at
least 10 hours at 85 C (185 F) or 12 hours at 80 C (176 F)
before going into service.

SE 84LV may be cured at higher temperatures for a shorter
time. At a cure temperature of 100 C (212 F) cure can be
achieved in 3 hours or at 120 C (250 F) cure can be achieved
in 1 hour.

It is not recommended to cure SE 84LV under vacuum
pressures of less than 85%. If a ramp rate of less than
0.3 C/min (0.5 F/min) is used, users should satisfy themselves
that this allows adequate flow.

CURING AT 80 C (176 F)
When curing at 80 C (176 F) it is important to ensure the
temperature is monitored off the trailing thermocouple. 80 C
(176 F) should be treated as the minimum cure temperature
for SE 84LV; 70-75 C (158-167 F) will not generate adequate
mechanical properties.

THIN LAMINATES
When using very thin laminates (e.g. with a total laminate fibre
weight of less than 300gm
2
), care needs to be taken to avoid
extracting excessive amounts of resin during the cure process.
To avoid this, a microporous release film can be used, and for
particularly critical components, a prepreg peel ply should be
used.

CORE BONDING

This product can be used in conjunction with typical core materials. Representative test panels should be made to ensure that the laminate
construction, curing method and other variables allow full filling of any cuts or slits in the foam. The cure cycles given in this datasheet are
for typical monolithic flat panels and may not be appropriate for sandwich panels.
When using Nomex or aluminium honeycombs, the separate SA 80 adhesive film is recommended and full details of use are provided on
the separate SA 80 data sheet. This adhesive film is supplied on a lightweight glass carrier, or in some cases it can be supplied directly
coated onto one face of the SE 84LV prepreg.
The system is fully compatible with Ampreg wet layup epoxy systems and therefore all types of cores may be bonded to a first skin by
using a separate wet-bonding operation. In this case, the addition of filler powders to the appropriate resin system is required to provide
the correct paste-like consistency.

All prepreg materials should be stored in a freezer when not in
use to maximise their useable life, since the low temperature
reduces the reaction of resin and catalyst to virtually zero.
However, even at -18 C (0 F), the temperature of most
freezers, some reaction will still occur. In most cases after
some years, the material will become unworkable.
When not in use SE 84LV products should be maintained at
-18 C (0 F). To avoid contamination on their surfaces, allow
rolls to reach room temperature before unwrapping.

SA 80

TOUGHENED EPOXY ADHESIVE FILM

Low temperature cure
Designed for bonding prepreg skins to honeycomb and foam cores
Compatible with Gurit SE84LV, SPARPREG, ST94 & ST95 products
Toughened for impact resistance and peel strength
Controlled flow for maximum bond integrity
Lloyd s Register certified formats

INTRODUCTION
SA 80 adhesive film is a toughened film unsupported or on a glass carrier with excellent tack and drape characteristics.
It offers many advantages over traditional wet lay-up techniques for bonding
of composite skins to cores, including; consistent bond-line thickness and
weight, high strain to failure, high toughness, handling convenience,
controlled flow and an 8 week out-life at ambient temperature (18-22 C/64-
72 F).

PDS-SA80-16-0224 2

INSTRUCTIONS FOR USE

CURING SCHEDULE
CORE BONDING
Various core materials can be used with the adhesive film system,
including certain foams (provided that special procedures are
followed) and honeycombs.

The system is fully compatible with Ampreg and Spabond formulated
resin systems.

NOMEX OR ALUMINIUM HONEYCOMB CORES
1. Core to First Skin
For bonding honeycomb into place onto a cured laminate, a minimum
of a 250g film should be used, with extra resin film used where there
are any steps, wrinkles or unevenness in the laminate. Apply the film
over the laminate with the paper side uppermost then remove the
release paper. Bed in the honeycomb core to the film and splice the
core segments with a wrap of at least two layers of film applied to
each honeycomb edge. After positioning all the core pieces, vacuum
the core in place using at least 80% vacuum and cure the adhesive
film for a minimum of 4 hours at 85 C (185 F). The full cure required
will be achieved when the outer skin is cured and bonded into place,
using one of the cure cycles below.

2. Second Skin to Core
One procedure is to co-cure the outer skin together with the core
bond. For this, a single layer of 250g adhesive film should be rolled
over the honeycomb surface, and bedded well into the cells. In this
way it should be possible to reposition misplaced prepreg plies,
without disturbing the adhesive layer. With a controlled flow system
such as SE 70, care should be taken to ensure that excess resin is
not removed from the adhesive interface, by using a fine microporous
release film. It is also critical when using this process that adequate
precautions are taken to perforate the SA 80 skin to allow air removal
from the Nomex prior to gelation. Failure to do so will result in skin
blow off (contact Gurit Technical Services or see SE 84LV / SA 80
Processing Notes for details).

PVC FOAM
Due to the wide variety of PVC and other foams available and the
cure temperatures involved, special procedures have been
developed which must be carefully followed when using foam with SA
80. Use of SA 80 with untreated PVC foams is not recommended due
to potential inhibition of cure.

CORECELL FOAM
Use of Corecell foam is preferable to PVC.

For full cure of SA 80 to be achieved, one of the following cure
cycles is recommended. If SA 80 is being co-cured with a
prepreg skin, then the cure cycle used for SA 80 will also be that
of the prepreg in the laminate. Where required cure cycle of the
prepreg being used and the SA 80 is different, then whichever
cure is the longest should be applied.

VACUUM TECHNIQUES
Consolidation of the core bond can be obtained either by
vacuum or pressure bags. Heating can be economically and
effectively achieved with either space heaters under an
insulated tent or heated blankets with insulation on top. Details
of the various types of system are available from Technical
Services.

A schematic diagram of a typical vacuum bag arrangement is
shown below.

All prepreg materials should be stored in a freezer when not in
use to maximise their useable life, since the low temperature
reduces the reaction of resin and catalyst to virtually zero.
However, even at -18 C (0 F), the temperature of most freezers,
some reaction will still occur. In most cases after some years,
the material will become unworkable.
