Product Use

Dabco PT303 is a strong foaming, low odor tertiary amine catalyst with properties similar to, but much lower odor than, Polycat 5 that strongly catalyzes the urea (water-isocyanate) reaction;

Dabco PT303 can be used in different types of rigid foams, especially rigid spray foams;

The dosage of Dabco PT303 can be adjusted according to the formulation, actual application and requirements;

Dabco PT303 can be used in spray foam in combination with Dabco PT302 and Dabco PT304.

Profile.

Dabco PT303 catalyst is a highly efficient polyurethane tertiary amine complex that strongly catalyzes the urea (water-isocyanate) reaction in rigid spray polyurethane foams, resulting in a significant increase in foaming reaction time. dabco PT303 catalyst contains isocyanate reactive groups that chemically bind to the polyurethane foam matrix, thereby reducing the odor of the spray foam.
