General information about the system Epoxy Resin L with different hardeners

• Low viscosity, free of solvents and fillers
• Fast impregnation of glass, aramid fiber and carbon fibers
• High static and dynamic strength

Epoxy resin L with the corresponding hardeners is the most widely used laminating and bonding resin in the R&G product range.

With hardeners S (15 minutes), L (40 minutes), CL (60 minutes), EPH 500 (60 minutes), EPH 161 (90 minutes), W 300 (300 minutes), GL 1 (30 minutes) and GL 2 (210 minutes), it has mechanical properties similar to those of the laminating systems commonly used in aviation. The heat distortion temperature ranges from 60 °C (S, L, EPH 500, W 300), over 80 °C (GL 1 and GL 2, after heat curing), 95 °C (CL, after heat curing) to 120 °C (EPH 161, after heat curing).

Epoxy Resin L is low viscosity, solvent and filler free and ideal for impregnating glass, aramid and carbon fibers. Its low surface tension, good adhesion and low curing shrinkage make it ideal for bonding wood, metal, Styrofoam®, etc. It can be processed by all common methods such as hand lay-up, pressure and vacuum impregnation as well as pressing and winding.

• The proven R&G Epoxy Resin L, with the newly developed GL 1 and GL 2 hardeners, has been approved by Germanischer Lloyd for the construction of boats and rotor blades for wind turbines.
• Expert opinion on the resin systems Epoxy Resin L + Hardener S, Epoxy Resin L + Hardener L, Epoxy Resin L + Hardener CL and Epoxy Resin L + Hardener EPH 500: these systems are not cytotoxic (harmful to cells), important for applications in medical technology.
• Laminate structures for vehicle construction in combination with Hardener EPH 161 are approved by TÜV.
