High Performance Epoxy Laminating System High temperature resistance laminating system For pre-preg tooling or high temperature parts TG max up to 130º C RESOLTECH 1040 - 1040T 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 . 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.

Resin 1040 (T) Hardeners 1041 SL & HT 1042HT MIXING RATIO WARNING: The mixing ratio must be accurately followed. It is not possible to change the ratio,it would result in lower mechanical properties. The mixture should be thoroughly stirred to ensure full homogeneity. It is important to note that epoxy systems tend to heat up much faster in a pot than as a thin film. It is therefore necessary to only mix the necessary amount usable within the given pot life. Keeping the mixture in flat open containers reduces the risks of exothermic reaction. APPLICATION The standard procedure of working with...

Resin 1040 (T) Hardeners 1041 SL & HT 1042HT CURING & POST CURING Curing prior to mould release is mandatory. The lowest admissible cure is 12h @ 40ºC or preferably 8h @60ºC. Postcuring is mandatory in order to obtain a material at the maximum of its mechanical properties with a TG of up to 130ºC Posrcuring cycle and temperature will depend on the thickness of the laminate as it has been observed that every 7,5 mm of thickness, temperature drops in the laminate due to the high heat insulation properties of the epoxy resins. In case of doubt, contact us. As general reference, postcuring should...
