Capcure WR-6 Mercaptan Cognis Crosslinking / Coupling / Curing Agents >> Mercapto Compounds Epoxy Resins CAPCURE® WR-6 is a pre-catalyzed mercaptan based epoxy hardener which provides fast gel times even in thin films at below freezing temperatures. Its excellent physical properties, improved moisture resistance and low viscosity expand formulating and application capabilities. Provides... Rapid Cures Improved Low Temperature Cures Rapid Thin Film Cures Improved Moisture Resistance Low Viscosity Gel Time Control High Filler Loading Capacity Reduced Induction Times of Polyamide Cures Increased Gloss For Coatings When CAPCURE® WR-6 is employed as the sole curing agent, use level of 79 phr is recommended. This level correspond to 80% stoichiometry (80% of the epoxy groups are reacted with this mercaptan hardener). The remaining epoxy groups are co-polymerized by catalysts which are contained in CAPCURE® WR-6. Pre-catalyzed mercaptan based epoxy hardener. Used for coatings. Provides rapid cures, improved low temperature cures, rapid thin film cures, improved moisture resistance, low viscosity, gel time control, high filler loading capacity, reduced induction times of polyamide cures and increased gloss. <br> Use level: 79 phr.
