Specialty amine catalysts for foaming
Our POLYCAT® brand includes a large variety of special catalysts that provide high performance foam reactions to meet the demands in applications such as spray foam. We have managed to optimize many of these products towards low emission profiles to exhibit low odor, and depending on the composition and combination, these catalysts can balance blow and gel activities.
Conventional catalysts accelerate the polyol-isocyanate reaction irrespective of temperatures. For situations requiring a delayed reaction and prolonged pot-life we propose our POLYCAT® SA range of temperature-activated catalysts. The natural exotherm generated during the polyurethane reaction or an external heat source can activate these catalysts at specific temperatures. The right combination of POLYCAT® SA catalysts allows formulators to tailor the viscosity build-up to the required balance of front-end delay and back-end cure.
