DESCRIPTION
Firepel K130 series resins are designed for
fire resistant applications where ASTM E
84 Class I flame is required. Flammability
of composite parts is dependent on the
geometry of the part, degree of cure,
reinforcement content, types of reinforce-
ment, etc. It is the end user’s responsibil-
ity to ensure that finished parts meet the
required specifications. Published flamma-
bility properties should be used for com-
parison purposes only.
Firepel K130-72 is the concentrated high-
ly brominated base resin that is used to
manufacture the other versions.
APPLICATION
Suitable for various fabricating methods
such as hand lay-up, spray-up, filament
winding, etc.
BENEFITS
Fire Retardant
Firepel K130 PT, NN and TT series meet
ASTM E 84 Class I flame spread require-
ments without the addition of fillers or
antimony.
Certain laminate constructions can meet
Class I smoke requirements. See
Flammability Property Table .
Low VOC
All Firepel K130 versions contain less than
35% styrene.
Versatile
The Firepel K130 series molecular archi-
tecture provides an excellent balance of
fire retardant, physical properties and cost.

2 – Smoke development of less than 450 is required for Class 1 rating.
** The degree of fire resistance of a cured resin is characterized by the ASTM E
84 test. This test is performed under strictly controlled conditions where a
flame spread rating is assigned according to comparisons with test set-point
materials. The behavior of the end-users composite cured under controlled
condition can vary significantly in an actual fire situation due to the large
number of unpredictable variables associated with actual fire situations.

FIREPEL
K130 SERIES POLYESTER RESIN
PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total resin
weight.
B. Maintain shop temperatures be-
tween 65 F/18 C and 90 F/32 C
and humidity between 40% and 90%.
Consistent shop conditions contribute
to consistent gel time and will help the
fabricator make a high quality part.
STORAGE STABILITY
This product is stable for three months
from the date of manufacture when
stored in the original containers, away
from direct sunlight or other UV light
sources and at or below 77 F/25 C.
After extended storage, some drift may
occur in the product viscosity and gel
time.
SAFETY
See the appropriate Material Safety
Data Sheet for guidelines.
APPLICATION GUIDELINES
A. Halogen containing resins are gen-
erally less resistant to UV light than
general purpose resins. Fabricators
are advised to conduct their own tests
to determine the suitability of using
Firepel K130 Series resins for outdoor
applications.
B. Due to the curing characteristics
of the Firepel K130 Series resins, it is
desirable to complete all secondary
bonding as soon as possible. Exposure
of the laminate to sunlight will result in
severe secondary bonding, especial-
ly if the surface of the laminate has
been allowed to become resin rich.
Low fiberglass content and resin pud-
dling should be avoided with this prod-
uct. To assure adequate bonding to
gel coats, fabricators should pre-wet
the gel coat surface with a thin pass of
catalyzed resin prior to lamination.
C. Chemical resistance studies have
indicated the dicyclopentadiene resins
such as Firepel K130 Series resins
have inferior resistance to certain hy-
drophobic liquids such as hydrocar-
bons. Fuel storage tanks should not
be produced with the Firepel K130
Series resins.
If your manufacturing needs require a
more corrosion resistant resin, please
contact your AOC representative for
information or technical assistance on
AOC’s line of isophthalic or vinyl ester
resins.
ISO 9001:2008 CERTIFIED
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2008 standards. This certifica-
tion recognizes that each AOC facility
has an internationally accepted model
in place for managing and assuring
quality. We follow the practices set
forth in this model to add value to the
resins we make for our customers.
FOOTNOTES
(1.) Based on tests of Firepel K130 base resin at
77 F/25 C and 50% relative humidity. All tests per-
formed on unreinforced cured resin castings. Thixo-
tropic components, if applicable are excluded from
casting samples. Castings prepared using 1.0% MEKP,
0.10% Cobalt 12%, post cured for 5 hours at 212
F/100 C.
(2) The gel times shown are typical but may be affected
by catalyst, promoter, inhibitor concentration, resin,
mold, and shop temperature. Variations in gelling char-
acteristics can be expected between different lots of
catalysts and at extremely high humidities. Pigment
and/or filler can retard or accelerate gelation. It is rec-
ommended that the fabricator check the gelling charac-
teristics of a small quantity of resin under actual operat-
ing conditions prior to use.

flame spread rating is assigned according to comparisons with test set-point
materials. The behavior of the end-users composite cured under controlled
condition can vary significantly in an actual fire situation due to the large
number of unpredictable variables associated with actual fire situations.

FIREPEL
K130 SERIES POLYESTER RESIN
PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total resin
weight.
B. Maintain shop temperatures be-
tween 65 F/18 C and 90 F/32 C
and humidity between 40% and 90%.
Consistent shop conditions contribute
to consistent gel time and will help the
fabricator make a high quality part.
STORAGE STABILITY
This product is stable for three months
from the date of manufacture when
stored in the original containers, away
from direct sunlight or other UV light
sources and at or below 77 F/25 C.
After extended storage, some drift may
occur in the product viscosity and gel
time.
SAFETY
See the appropriate Material Safety
Data Sheet for guidelines.
APPLICATION GUIDELINES
A. Halogen containing resins are gen-
erally less resistant to UV light than
general purpose resins. Fabricators
are advised to conduct their own tests
to determine the suitability of using
Firepel K130 Series resins for outdoor
applications.
B. Due to the curing characteristics
of the Firepel K130 Series resins, it is
desirable to complete all secondary
bonding as soon as possible. Exposure
of the laminate to sunlight will result in
severe secondary bonding, especial-
ly if the surface of the laminate has
been allowed to become resin rich.
Low fiberglass content and resin pud-
dling should be avoided with this prod-
uct. To assure adequate bonding to
gel coats, fabricators should pre-wet
the gel coat surface with a thin pass of
catalyzed resin prior to lamination.
C. Chemical resistance studies have
indicated the dicyclopentadiene resins
such as Firepel K130 Series resins
have inferior resistance to certain hy-
drophobic liquids such as hydrocar-
bons. Fuel storage tanks should not
be produced with the Firepel K130
Series resins.
If your manufacturing needs require a
more corrosion resistant resin, please
contact your AOC representative for
information or technical assistance on
AOC’s line of isophthalic or vinyl ester
resins.
ISO 9001:2008 CERTIFIED
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2008 standards. This certifica-
tion recognizes that each AOC facility
has an internationally accepted model
in place for managing and assuring
quality. We follow the practices set
forth in this model to add value to the
resins we make for our customers.
FOOTNOTES
(1.) Based on tests of Firepel K130 base resin at
77 F/25 C and 50% relative humidity. All tests per-
formed on unreinforced cured resin castings. Thixo-
tropic components, if applicable are excluded from
casting samples. Castings prepared using 1.0% MEKP,
0.10% Cobalt 12%, post cured for 5 hours at 212
F/100 C.
(2) The gel times shown are typical but may be affected
by catalyst, promoter, inhibitor concentration, resin,
mold, and shop temperature. Variations in gelling char-
acteristics can be expected between different lots of
catalysts and at extremely high humidities. Pigment
and/or filler can retard or accelerate gelation. It is rec-
ommended that the fabricator check the gelling charac-
teristics of a small quantity of resin under actual operat-
ing conditions prior to use.

DESCRIPTION
Firepel K130 series resins are designed for
fire resistant applications where ASTM E
84 Class I flame is required. Flammability
of composite parts is dependent on the
geometry of the part, degree of cure,
reinforcement content, types of reinforce-
ment, etc. It is the end user’s responsibil-
ity to ensure that finished parts meet the
required specifications. Published flamma-
bility properties should be used for com-
parison purposes only.
Firepel K130-72 is the concentrated high-
ly brominated base resin that is used to
manufacture the other versions.
APPLICATION
Suitable for various fabricating methods
such as hand lay-up, spray-up, filament
winding, etc.
BENEFITS
Fire Retardant
Firepel K130 PT, NN and TT series meet
ASTM E 84 Class I flame spread require-
ments without the addition of fillers or
antimony.
Certain laminate constructions can meet
Class I smoke requirements. See
Flammability Property Table .
Low VOC
All Firepel K130 versions contain less than
35% styrene.
Versatile
The Firepel K130 series molecular archi-
tecture provides an excellent balance of
fire retardant, physical properties and cost.

DESCRIPTION
Firepel K130 series resins are designed for
fire resistant applications where ASTM E
84 Class I flame is required. Flammability
of composite parts is dependent on the
geometry of the part, degree of cure,
reinforcement content, types of reinforce-
ment, etc. It is the end user’s responsibil-
ity to ensure that finished parts meet the
required specifications. Published flamma-
bility properties should be used for com-
parison purposes only.
Firepel K130-72 is the concentrated high-
ly brominated base resin that is used to
manufacture the other versions.
APPLICATION
Suitable for various fabricating methods
such as hand lay-up, spray-up, filament
winding, etc.
BENEFITS
Fire Retardant
Firepel K130 PT, NN and TT series meet
ASTM E 84 Class I flame spread require-
ments without the addition of fillers or
antimony.
Certain laminate constructions can meet
Class I smoke requirements. See
Flammability Property Table .
Low VOC
All Firepel K130 versions contain less than
35% styrene.
Versatile
The Firepel K130 series molecular archi-
tecture provides an excellent balance of
fire retardant, physical properties and cost.

2 – Smoke development of less than 450 is required for Class 1 rating.
** The degree of fire resistance of a cured resin is characterized by the ASTM E
84 test. This test is performed under strictly controlled conditions where a
flame spread rating is assigned according to comparisons with test set-point
materials. The behavior of the end-users composite cured under controlled
condition can vary significantly in an actual fire situation due to the large
number of unpredictable variables associated with actual fire situations.

FIREPEL
K130 SERIES POLYESTER RESIN
PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total resin
weight.
B. Maintain shop temperatures be-
tween 65 F/18 C and 90 F/32 C
and humidity between 40% and 90%.
Consistent shop conditions contribute
to consistent gel time and will help the
fabricator make a high quality part.
STORAGE STABILITY
This product is stable for three months
from the date of manufacture when
stored in the original containers, away
from direct sunlight or other UV light
sources and at or below 77 F/25 C.
After extended storage, some drift may
occur in the product viscosity and gel
time.
SAFETY
See the appropriate Material Safety
Data Sheet for guidelines.
APPLICATION GUIDELINES
A. Halogen containing resins are gen-
erally less resistant to UV light than
general purpose resins. Fabricators
are advised to conduct their own tests
to determine the suitability of using
Firepel K130 Series resins for outdoor
applications.
B. Due to the curing characteristics
of the Firepel K130 Series resins, it is
desirable to complete all secondary
bonding as soon as possible. Exposure
of the laminate to sunlight will result in
severe secondary bonding, especial-
ly if the surface of the laminate has
been allowed to become resin rich.
Low fiberglass content and resin pud-
dling should be avoided with this prod-
uct. To assure adequate bonding to
gel coats, fabricators should pre-wet
the gel coat surface with a thin pass of
catalyzed resin prior to lamination.
C. Chemical resistance studies have
indicated the dicyclopentadiene resins
such as Firepel K130 Series resins
have inferior resistance to certain hy-
drophobic liquids such as hydrocar-
bons. Fuel storage tanks should not
be produced with the Firepel K130
Series resins.
If your manufacturing needs require a
more corrosion resistant resin, please
contact your AOC representative for
information or technical assistance on
AOC’s line of isophthalic or vinyl ester
resins.
ISO 9001:2008 CERTIFIED
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2008 standards. This certifica-
tion recognizes that each AOC facility
has an internationally accepted model
in place for managing and assuring
quality. We follow the practices set
forth in this model to add value to the
resins we make for our customers.
FOOTNOTES
(1.) Based on tests of Firepel K130 base resin at
77 F/25 C and 50% relative humidity. All tests per-
formed on unreinforced cured resin castings. Thixo-
tropic components, if applicable are excluded from
casting samples. Castings prepared using 1.0% MEKP,
0.10% Cobalt 12%, post cured for 5 hours at 212
F/100 C.
(2) The gel times shown are typical but may be affected
by catalyst, promoter, inhibitor concentration, resin,
mold, and shop temperature. Variations in gelling char-
acteristics can be expected between different lots of
catalysts and at extremely high humidities. Pigment
and/or filler can retard or accelerate gelation. It is rec-
ommended that the fabricator check the gelling charac-
teristics of a small quantity of resin under actual operat-
ing conditions prior to use.

Storage stability of two months or less
should be anticipated if the storage
temperature exceeds 30 C (86 F).
After extended storage, some drift may
occur in the product viscosity and gel
time.

ISO 9001:2015 CERTIFIED
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2015 standards. This certifica-
tion recognizes that each AOC facility
has an internationally accepted model
in place for managing and assuring
quality. We follow the practices set

FOOTNOTES
(1.) Based on tests of Vipel K022 at 77 F/25 C and
50% relative humidity. All tests performed on unrein-
forced cured resin castings. Thixotropic components, if
applicable, are excluded from casting samples. Cast-
ings were prepared using 1.0% BPO and post cured 2
hours at 138 C.
(2.) The gel times shown are typical but may be affect-
ed by catalyst, promoter, inhibitor concentration, resin,
mold, and shop temperature. Variations in gelling char-
acteristics can be expected between different lots of
catalysts and at extremely high humidities. Pigment
and fillers can retard or accelerate gelation. It is recom-
mended that the fabricator check the gelling character-
istics of a small quantity of resin under actual operating
conditions prior to use.

DESCRIPTION
AOC’s Vipel K022 series are brominated bi-
sphenol-A epoxy vinyl ester resins dissolved in
styrene.
APPLICATION
Vipel K022 series is ideally suited for use in
hand lay-up, spray-up, filament winding and
pultrusion processes where outstanding me-
chanical properties and excellent resistance to
chemicals and heat are required.
All versions of the K022 Series do not meet
ASTM E84 Class 1 smoke requirements.
BENEFITS
Versatile
Vipel K022 is available in a wide range of for-
mulations, which allows the product to be used
in many processes and also optimizes
cost/performance.
Vipel K022-CN versions already contain an
antimony product to meet a Class 1 flame
spread.
Fire Retardant
Because of the versatility of Vipel K022, ver-
sions are available to meet ASTM E 84 Class 1
or 2 flame spread.
Mechanical Properties
Vipel K022 is suitable for moldings that are
subjected to particularly high static or dynamic
loads.
Corrosion Resistance
Vipel K022 is highly resistant to a number of
chemical environments. Refer to AOC’s
“Corrosion Resistant Resin Guide” for corrosion
resistance information or for questions regard-
ing suitability of a resin to any particular chemi-
cal environment contact AOC.
Vipel K022-CN versions are not recommended
for use in the corrosion liner.

PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.5% of the total
resin weight.
B. Maintaining shop temperatures
between 65 F/18 C and 90
F/32 C and humidity between 40%
and 90% will help the fabricator
make a high quality part. Consistent
shop conditions contribute to con-
sistent gel times and will help the
fabricator make a high quality part.
C. Finished part surfaces that have
been cured at room temperature in
contact with air should be relatively
tack free. They may not, however,
be fully cured and are thus not as
resistant to chemicals as a fully
cured part. If no further laminating
is planned, a 10% solution of 5%
paraffin wax solution (MP
115-118 F/46-48 C) in styrene
may be added to the last resin layer
to provide a tack free surface.
D. Optimum cure and performance
may be obtained by post curing
room temperature cured laminates
for two hours at 158-212 F/70-
100 C.
E. Room temperature curing by
means of cobalt acceleration
should be completed with low hy-
drogen peroxide content MEKP cat-
alyst, such as MEKP 925H, to mini-
mize foaming.

Note: The degree of fire resistance of a cured resin is characterized by the ASTM E 84 test. This test is performed under strictly controlled
conditions where a flame spread rating is assigned according to comparisons with test set-point materials. The behavior of the end-users
composite cured under controlled conditions can vary significantly in an actual fire situation due to the large number of unpredictable varia-
bles associated with actual fire situations.

PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.0% – 2.5% of the total
resin weight.
B. Maintaining shop temperatures
between 65 F/18 C and 90
F/32 C and humidity between 40%
and 90% will help the fabricator
make a high quality part. Consistent
shop conditions contribute to con-
sistent gel times and will help the
fabricator make a high quality part.
C. Finished part surfaces that have
been cured at room temperature in
contact with air should be relatively
tack free. They may not, however,
be fully cured and are thus not as
resistant to chemicals as a fully
cured part. If no further laminating
is planned, a 10% solution of 5%
paraffin wax solution (MP
115-118 F/46-48 C) in styrene
may be added to the last resin layer
to provide a tack free surface.
D. Optimum cure and performance
may be obtained by post curing
room temperature cured laminates
for two hours at 158-212 F/70-
100 C.
E. Room temperature curing by
means of cobalt acceleration
should be completed with low hy-
drogen peroxide content MEKP cat-
alyst, such as MEKP 925H, to mini-
mize foaming.
STORAGE STABILITY
Vipel K022-ACP-20, K022-ACT-30,
K022-ACT-45, K022-CCK-18, K022-
CNP-25 and K022-EAA-40 are sta-
ble for 3 months from the date of
manufacture when stored in origi-
nal containers, away from direct
sunlight or other UV light sources
and at or below 77 F (25 C). All
other Vipel K022 products are sta-
ble for 6 months from the date of
manufacture when stored in origi-
nal containers, away from direct
sunlight or other UV light sources
and at or below 77 F (25 C).
Storage stability of two months or
less should be anticipated if the
storage temperature exceeds 86 F
(30 C).
After extended storage, some drift
may occur in the product viscosity
and gel time.
SAFETY
See the appropriate Safety Data
Sheet for guidelines.
ISO 9001:2008 CERTIFIED
The Quality Management Systems
at every AOC manufacturing facility
have been certified as meeting ISO
9001:2008 standards. This certifi-
cation recognizes that each AOC
facility has an internationally ac-
cepted model in place for managing
and assuring quality. We follow the
practices set forth in this model to
add value to the resins we make for
our customers.
FOOTNOTES
(1.) Based on tests of Vipel K022 at 77 F/25 C
and 50% relative humidity. All tests performed on
unreinforced cured resin castings. Thixotropic com-
ponents, if applicable, are excluded from casting
samples. Castings were prepared using 1.0% BPO
and post cured 1 hour at 93 C, 1 hour at 116 C
and 2 hours at 138 C.
(2.) The gel times shown are typical but may be
affected by catalyst, promoter, inhibitor concentra-
tion, resin, mold, and shop temperature. Variations
in gelling characteristics can be expected between
different lots of catalysts and at extremely high
humidities. Pigment and fillers can retard or accel-
erate gelation. It is recommended that the fabrica-
tor check the gelling characteristics of a small quan-
tity of resin under actual operating conditions prior
to use.
