POLYCAT® 8 is a standard catalyst for a broad range of rigid foams. POLYCAT® SA 1 is a heat-activated, delayed-action polyurethane catalyst that is based on a strong cyclic amine called 1,5-diaza-bicyclo (5. Major applications include all continuous and discontinuous applications such as rigid slabstock, board laminate and refrigeration formulations. In industries such as oil and gas, Ammonia, Methane, DRI. polycat® 15 can also be used as a curing agent as a copper remover for semiconductor ma as a feedstock for cationic surfactants. It provides a balanced promotion of the urethane and urea reactions flexible as well as rigid foam applications. It is used in all-water-blown TDI or TDI/MDI high resilience (HR) foam and in TDI/MDI- or MDI-based, cold-cure molded polyurethane cushioning foam systems. It possesses very good performance in water co-blown rigid systems. It improves the surface cure in flexible molded systems.
