Epoxy Resin L

General information about the system Epoxy Resin L with different hardeners

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

Epoxy Resin L with the corresponding hardeners is the most commonly used laminating and adhesive resin in the R&G delivery programme.

In conjunction with the 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), this epoxy resin exhibits similar mechanical properties to those of the laminating systems usual aerospace .Its heat deflection temperature reaches from 60 °C (S, L, EPH 500, W 300), to 80 °C (GL 1 and GL 2, after post-curing), to 95 °C (CL, after post-curing) and finally to 120 °C (EPH 161, after post-curing).

Epoxy Resin L has a low viscosity, is free of solvents and fillers, and ideal for impregnating glass, aramid, and carbon fibres. Its low surface tension, good adhesion, and minimal curing shrinkage makes it ideal for bonding wood, metal, foamed polystyrene, etc. It can be processed in all of the customary methods, e.g. hand lay-up operations, pressure and vacuum impregnation, press moulding, winding, etc.

• The well-proven R&G Epoxy Resin L in combination with Hardeners GL 1 and GL 2 offer an approval by the Germanische Lloyd for the construction of boats and rotor blades for wind turbines.
• Expertise for 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 are not cytotoxic (cell damaging), important for applications in medical purposes.
• Laminate structures for vehicle construction in combination with Hardener EPH 161 are approved by the TÜV-Süd (Document available in german language only).
