AlzChem DYHARD® Epoxy Fluid System for Filament Winding
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	DYHARD® Fluid curing system for filament winding processes consists of DYHARD® RF2100 low viscosity modified BPA epoxy resin and DYHARD® Fluid 212 latent liquid curing agent. This curing system offers relative fast cure at elevated temperatures, long pot life in the impregnation bath, and has ideal viscosity for impregnation. The system is recommended for the production of CNG and H2 pressure cylinders. Property data is reported for a DYHARD® RF2100: DYHARD® Fluid212 = 100:10 ratio. Information provided by Alzchem LLC.
