Polycat® 31 Amine Catalyst for Spray Polyurethane Foam (SPF) NEW!
Polycat 31 catalyst was developed to specifically provide the reaction rate and selectivity of traditional amine catalysts like Dabco® BL-11 catalyst, while reducing the emissions and related issues associated with amines during the foam application and post cure. This presentation explains the reactivity and emission concerns of these systems and how Polycat 31 catalyst addresses them. (17:47)

Fundamentals of Polyurethane Catalysis Find out how blow-to-gel selectivities are obtained using a foam model run under realistic conditions of reactant stoichiometry, concentration, and temperature. This presentation examines the impact of catalyst concentration and structure, isocyanate and alcohol structure, and temperature on catalyst selectivity.

This presentation is divided into 5 parts:
Part 1 - Review of Foam Model (14:56)	> play presentation
Part 2 - Effect of Concentration on Selectivity (07:39)	> play presentation
Part 3 - Effect of NCO Steric Hindrance on Selectivity (10:48)	> play presentation
Part 4 - Effect of Alcohol Steric Hindrance on Selectivity (14:16)	> play presentation

Advances in Catalyst Performance for Polyurethane Spray Foam Systems
Polycat 30 catalyst is new catalyst technology that can replace DMEA in rigid and rigid spray foam systems. Benefits include reduced odor, reduced use level offering cost-effectiveness and lower emissions, physical properties equal to or improved when compared to DMEA, and improved system stability (hydrolysis).
