SA 80 is a film adhesive suitable for secondary bonding, core-bonding, and co-curing with Gurit prepregs, curing at temperatures as low as 80°C with an out-life of 56 days at room temperature. It is available in 150, 250, and 400g resin films, with or without a glass carrier, ideal for core bonding and high toughness applications.

SF 70 Toughened Surfacing Film
SF 70 is a light green, toughened epoxy film designed to enhance the surface finish of moulded composite components, providing a resin-rich surface when co-cured with 70°C prepregs, suitable for post-painting applications.

SF 80 Toughened Surfacing Film
Similar to SF 70, SF 80 is a toughened epoxy film that enhances the surface finish of composite components, used with 80°C prepregs, offering improved resistance to water ingress and reduced interfacial voids.

SF 95 Abrasion-Resistant Surfacing Film
SF 95 is a grey filled, sandable epoxy film providing a Class A surface finish, abrasion-resistant and stable up to 125°C, suitable for applications requiring a durable surface.

SF 95PF Sandable Surfacing Film
SF 95PF is designed for a pinhole-free laminate surface, ideal for sanding and priming before painting, co-curing with 85°C prepregs, offering improved opacity and water resistance.

SF 95VH Abrasion-Resistant Surfacing Film
SF 95VH is a hard, abrasion-resistant epoxy film that protects underbody components from damage, increasing surface longevity, suitable for applications like car body undertrays.

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...
