Advanced epoxy laminating system formulated to manufacture high performance lightweight structures with glass, carbon, aramid and basalt fibres with post-curing. This excellent wetout system is recommended for the manufacture of tools and composite parts that require to resist to temperatures under load up to 130ºC.
Advanced epoxy laminating system formulated to manufacture high performance lightweight structures with glass, carbon, aramid and basalt fibres with post-curing.
This excellent wetout system, optimized with a low reactivity, low viscosity and excellent air release properties, is recommended for the manufacture of tools and composite parts that require to resist to temperatures under load up to 130ºC.
Gelcoat Resolcoat 7090/7091T is recommended for the production of tooling together with Resoltech 1040 and 1041HT hardener. This gelcoat is applied by brush and must cure for at least 12-24 hours at 23ºC. Then the laminate with Resoltech 1040/1041HT is accomplished.
This system is optimized for wet-layup but may be used by filament winding or casting when mixed with appropriate fillers & charges.
Typically, this system is used for the manufacture of 120ºC curing prepreg tooling or parts exposed to high temperatures such as composite motorbike or race car exhausts.
The 1040 resin may be ordered in it´s thixotropic version, the 1040T for parts or moulds with vertical or overhanging surfaces. It is also recommended as first coat for carbon laminates to avoid air entrapment at the warp and weft intersections of the fabric
It is recommended to cure the part or tool laminated at 60ºC in order to release from the mould or plug, but it is also possible to cure at temperatures as low as 40ºC with a longer curing time
The resulting structures will have high mechanical and interlaminar properties.

The standard procedure of working with epoxy systems applies this system. The 1040 system can be applied by brush, roller, infused or injected. In case of laminating over a cured surface without peel ply, it is required to deglaze, clean and degrease the support prior to laminating.
It is recommended to have workshop temperature conditions between 18-25°C in order to facilitate the mixing and the reinforcement fibers impregnation. A lower temperature will increase the viscosity of the mix as well as it’s pot life. On the contrary, a higher temperature will reduce the viscosity and the pot life of the mix.
