Composites

Gairesa formulates, manufactures and commercialises epoxy adhesives and resins specially designed for the production of composites with different techniques: hand lay-up, infusion, pultrusion, filament winding or prepregs.

The main applications in this sector are:


o    Automotive and aircraft industry: adhesives for different car and airplane parts, prepregs, primers for difficult substrates, etc.
o    Ship building industry: sports, recreational and fishing ships.
o    Sports industry: surfboards, kayaks, fishing rods, etc.
o    Wind energy industry: structural adhesives and resins for infusion, hand lay-up and prepregs.
o    Building industry: reinforcement and production of structural elements in bridges.

*Curing cycle recommended for GAIRECOM FW: 5 hours at 70ºC + 2 hours at 110ºC. Pot-life is not measurable at room temperature (20ºC).

**Curing cycle recommended for GAIRECOM 2006 LT SPORT: 5 hours at 90ºC. Pot-life is not measurable at room temperature (20ºC).

***Values for BEPOX 1637 obtained after curing 6 hours at 80ºC.

****Pot-life can be reduced with the addition of a third component which speeds up the reaction rate
