The specified requirements you`ll find on the R&G website. PoxySystems® is a registered trademark of R&G General information about the system "Epoxy resin L" with hardeners S, L, EPH 500 and EPH 161 •Low viscosity, free of solvents and fillers •Fast impregnation of glass, aramid, and carbonfibres •High static and dynamic strength Epoxy resin L with the corresponding hardeners S, L, EPH 500 and EPH 161, 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), EPH 500 (60 minutes) and EPH 161 (90 minutes), this epoxy resin exhibits strengths similar to those of the laminating systems usual in aviation. The heat distortion temperature ranges from 60 °C (S, L, EPH 500) to approx. 120 °C (EPH 161, after heat curing). Epoxy resin L has a low viscosity, is free of solvents and fillers, and is 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.
