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.

To maximise the de-frosted shelf life of the material it is beneficial to maintain a cool working environment. When not in use, SE84LV
products should be stored at -18 C (0 F).
TYPICAL CURE TIME AND TEMPERATURES
All temperatures measured by thermocouple installed on the laminate surface. Vacuum should be maintained as high as possible
throughout the cure cycle. 80 C (176 F) should be treated as the minimum cure temperature; lower temperatures may not generate
adequate mechanical properties.

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
extensive sanding operations a shower/bath and hair wash is advised.
Gurit produces a separate full Safety Data Sheet for all hazardous products. Please ensure that you have the correct SDS to hand for
the materials you are using before commencing work.
