Polyurethane Catalyst A33 is a gel catalyst mainly used as polyurethane foam.
The active ingredient of polyurethane catalyst A33 is triethylene diamine, the solution prepared by 33% of triethylene diamine and 67% of monoconjugated dipropylene glycol is mainly used as gel catalyst for polyurethane foam, which is widely used in flexible, semi-rigid, rigid polyurethane foam, coating, elastomer, In polyurethane foaming system, isocyanate firstly reacts with triethylene diamine to generate active complex. The nature of the complex is very unstable, once the urethane bond is generated, it will be free, which is conducive to further catalyzing, triethylenediamine has a strong catalytic effect on the gel reaction and foaming reaction, especially on the polyurethane and hydroxyl catalytic effect is more selective.A33 is mainly used as gel catalyst for polyurethane foams, and it is widely used in flexible, semi-rigid, rigid polyurethane foams, elastomers, coatings, etc.
