Fiche Technique - 13/09/2007 RESOLTECH 1040 Hardener 1405 Infusion Epoxy Resin system High TG ~ 150°C Low viscosity and exceptional wetting properties RESOLTECH 1040 - 1405 is an epoxy resin system formulated for infusion applications. It enables to manufacture structural composites parts with all existing reinforcement fabrics. Thanks to its low viscosity and high wetting properties, it can be used by hand lay-up or via infusion, vaccum bagging and RTM . Once reticulated at ambient temperature, the parts should be post-cured according to the thermal cycle indicated in this datasheet in order to obtain the maximum mechanical properties of this resin system. It’s TG of 150°C enables the realisation of high quality and performance parts as well as tooling for prepreg parts. Page 1/5 RESOLTECH RESOLVING YOUR ENGINERING CHALLENGES www.resoltech.com

Resin 1040 Hardener 1405 Structural epoxy laminating system High TG ~ 150°C Low viscosity and exceptional wetting properties 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...
