INTRODUCTION
Gurit’s long history supplying prepregs to the wind energy, transportation and marine industries has
allowed Gurit to lead the way by introducing the next generation of prepregs, specifically designed
to make component manufacture faster, easier and cheaper.
Pre-impregnated materials (prepregs) are reinforcement fibres or fabrics into which a pre-catalysed
resin system has been impregnated by a machine. The resin systems in these materials react only
very slowly at room temperature, allowing a long shelf life and are cured by heating them to the
prescribed elavated temperature.
Gurit’s Prepreg offering is grouped into:
PERFORMANCE PREPREGS
High performance prepreg technology for the most demanding applications.
STRUCTURAL PREPREGS
Structural prepreg technology for faster, easier and cheaper large-scale composite components.

INTRODUCTION
INTRODUCTION
Gurit’s SE 70 is a hot melt, low temperature cure, epoxy prepreg system. It has been developed for use in the construction of large
components using low energy cure cycles. Excellent properties can be achieved with a processing temperature of just 70°C.
At this cure temperature the system exhibits very good mechanical properties and excellent toughness.
Cure temperature for a 16 hours cure cycle is 70°C - this temperature allows less expensive tooling and ovens to be used, with
lower thermal movement and distortion. Faster cures are available from higher cure temperatures. However, thicker sections
(>10mm) will require the insertion of a suitable dwell into the cure cycle. Up to 20mm thick laminates may be moulded at 70˚C with
a peak exotherm only slightly above the cure temperature.
SE 84LV is an exceptionally versatile hot-melt, epoxy prepreg. It can be cured at temperatures as low as 80°C, or for faster moulding
of components at 120°C. This is achieved with an extremely good out-life of up to 8 weeks at 18-22°C. SE 84LV is a toughened
system, and offers excellent mechanical properties on a wide variety of reinforcing fabrics and fibres and 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.
TYPICAL APPLICATIONS
SE 84LV 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.

INTRODUCTION
SE 200 is a high strength toughened epoxy system that has a flexible cure envelope ranging from 135°C to 200°C.
SE 200 has been developed to enable rapid part manufacture through a number of composite processing methods. The minimum
cure temperature is 135°C from which SE 200 develops a Tg and mechanical properties associated with higher temperature curing
systems. Higher temperature cures in excess of 180°C will achieve the best dry and wet thermal performance. Using the appropriate
press moulding technology it is possible to achieve a 15 minutes hot-in / hot-out cure at 195°C, making SE 200 suitable for the
economic production of automotive parts.
TYPICAL APPLICATIONS
SE 200 structural prepreg can be used in the making of parts such as structural lower tubs, bulkheads, front and rear scuttles, gearbox
tunnels and other structural components.

INTRODUCTION
PN 901/SE 300 is an ideal prepreg resin for high temperature composite applications, as it combines the ease of processing and
handling convenience of epoxy resins, high temperature stability of polyimides, and flame and fire resistance of phenolics.
A 120°C cure for 75 minutes combined with a post-cure, enables PN 901/SE 300 to generate a Tg in excess of 300°C, making PN 901/
SE 300 ideal for applications in composite structures, which are exposed to very high temperatures for short durations. The flame and
smoke characteristics of PN 901/SE 300 composites show that this resin possesses superior flame retardant properties and holds a
wide range of Aerospace grade FST (Fire/Smoke/Toxicity) standards.
TYPICAL APPLICATIONS
Stuctures for high tempertature applications such as engine cowlings.

Gurit SparPreg™ Spar Solution is now available in carbon and glass with Airstream™ coating technology. SparPreg™ featuring
Airstream™ coating technology is a specialised prepreg, developed to enable the economic manufacture of UD spar caps for most
demanding composite structure designs.
Conventional prepregs are processed using vacuum bag technology to remove the air between the plies prior to consolidation and
cure. However, as laminate thickness increases it is difficult to maintain high quality, low void content laminates without the use of
multiple de-bulking steps under controlled temperature conditions and/or the use of high pressure autoclaves to consolidate the plies.
Due to the size of spar caps and the manufacturing cost targets it is not always feasible to use multiple process steps, expensive
capital equipment, or invest in a tightly temperature controlled environment.

SF 80 surfacing material is a light green, toughened, epoxy film designed to enhance the surface finish of moulded composite
components. It allows a good surface finish to be obtained by vacuum-bag moulding processes. It can be used directly against a
suitably release treated mould surface, with prepreg or SPRINT™ plies laid up behind it. When fully cured with SPRINT™ or prepreg,
SF 80 forms a stable tough surface which can be sanded in preparation for painting. The epoxy system is supplied ready impregnated
into a supporting medium and ready catalysed, requiring only a moderate temperature cure.

INTRODUCTION
The patent-pending SF 95 surfacing material is a grey filled, sandable epoxy film designed to enhance the surface finish of moulded
composite components. It allows a Class A surface finish to be obtained by vacuum-bag moulding processes. It can be used directly
against a suitably release treated mould surface, with prepreg or SPRINT™ plies laid up behind it. When fully cured with SPRINT™ or
prepreg, SF 95 forms a stable sandable surface which, once lightly sanded to provide a key for painting, greatly reduces print through
of the underlying laminate. The epoxy system is supplied ready impregnated into a supporting medium and ready catalysed, requiring
only a moderate temperature cure.

TECHNICAL INFORMATION AND PRICING
INTRODUCTION
SF 95PF surfacing material is an epoxy film designed to enhance the surface finish of moulded composite components. It allows
a good surface finish to be obtained by vacuum-bag moulding processes. It can be used directly against a suitably release treated
mould surface, with prepreg or SPRINT™ plies laid up behind it. When fully cured with SPRINT™ or prepreg, SF 95PF forms a stable
sandable surface which, once lightly sanded to provide a key for painting, provides a pin-hole free laminate. The epoxy system is
supplied ready impregnated into a supporting medium and ready catalysed, requiring only a moderate temperature cure.

INTRODUCTION
Product Datasheets
SF 95VH surfacing material is a very hard, abrasion-resistant epoxy film. It is designed to protect vulnerable underbody components
from damage caused by foreign objects. Typical applications include inner wings, and front wheel diffusers. SF 95VH can be used
directly against a suitably release treated mould surface, with prepreg or SPRINT™ plies laid up behind it, or as a final layer in the
mould. It can be cured with vacuum only processing. Due to abrasion-resistance of this material, it would not be usual to apply a paint
finish. The epoxy system is supplied ready impregnated into a supporting medium and ready catalysed, requiring only a moderate
temperature cure.
TYPICAL APPLICATIONS
Ideal for applications that require a highly toughened system such as car body undertrays.
