Epoxy Base Set MAXI – Epoxy Resin L + Hardener L (40 min)

The Epoxy Base Set MAXI is based on the proven Epoxy Resin L with Hardener L and is a low-viscosity epoxy resin system for laminating and bonding in composite construction. The set is designed for larger quantities and recurring laminating work and includes extensive accessories for processing.

The epoxy resin system is one of the most frequently used laminating and bonding resin systems in the R&G product range and is used for glass fibre, carbon fibre and aramid fibre applications. The solvent-free and filler-free epoxy resin is free of nonylphenol and DETA. Its low surface tension ensures reliable adhesion to various substrates with low curing shrinkage.

Epoxy Resin L with Hardener L achieves mechanical properties comparable to laminating systems used in aircraft construction. It is suitable for structurally loaded laminates as well as for bonding wood, metal and Styropor®.
