Epoxy Resin L with the corresponding Hardeners S, L, CL, EPH 500, EPH 161, W 300, GL 1 and GL 2 is the most commonly used laminating and adhesive resin in R&G`s 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).
Its low surface tension, good adhesion, and minimal curing shrinkage makes the Epoxy Resin L ideal for bonding wood, metal, foamed polystyrene like Styropor® etc. It can be processed in all of the customary methods, e.g. hand lay-up, pressure and vacuum impregnation, press moulding and filament winding.
