Epoxy Resin L + Hardener EPH 500 (set of two components)
Технические характеристики
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.
Hardener EPH 500
• Hardener for epoxy resin L
• Processing time: 60 minutes
Characteristics:
• Delivered state: liquid
• Viscosity at 25 °C: 500 ± 100 mPa.s
• Active H equivalent: 112 g/equiv.

• Refractive index at 25 °C: 1.530 ± 0.002
• Min pot life with R&G L or L 20 epoxy resin (100 g formulation at 25 °C): approx. 60 min.
• Mixing ratio: 100 : 63 parts by weight
• curing time at room temperature: approx. 24 hours
Application
Hardener EPH 500 is used in combination with liquid epoxy resins, primarily in solvent-free varnishes, coatings and laminating resin. The resulting surfaces are tack-free and largely resistant to light and colour-fast. Owing to its low viscosity and long pot life this hardener is suitable for formulating sprayable systems that can be processed in single-constituent airless installations. Curing at 5 °C possible.
Shelf life hardener EPH 500
One year in sealed packaging at room temperature.
Expertise for the resin system epoxy resin L + hardener EPH 500: the system is not cytotoxic (cell damaging), important for applications in medical purposes!
