Content 33% Triethylene diamine solution

Form Solid

Application Flexible, semi-rigid, rigid urethane foam

Chemical composition:

33% solution of triethylenediamine.

Triethylenediamine is solid at room temperature and is not convenient for use as a polyurethane catalyst. In industrial applications, it is often melted in small molecule diols and configured to be used as an alcohol solution with a mass fraction of 33% (or other concentrations).

Commonly used diols are dipropylene glycol monoacetate, propylene glycol, diethylene glycol monoacetate (diethylene glycol), ethylene glycol and so on.

Product Usage:

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.
