33% triethylenediamine solution
Application Flexible, semi-rigid, rigid urethane foam
33% triethylenediamine solution.
Triethylenediamine is solid at room temperature and is inconvenient to use as a polyurethane catalyst. In industrial applications, it is often melted in a small molecule diol and configured to use an alcohol solution with a mass fraction of 33% (or other concentration).
Commonly used glycols include dipropylene glycol, propylene glycol, diethylene glycol (diethylene glycol), ethylene glycol and the like.

The effective component of polyurethane catalyst A33 is triethylenediamine, a solution made of 33% triethylenediamine and 67% dipropylene glycol. It is mainly used as a gel catalyst for polyurethane foams and is widely used in soft , Semi-rigid, rigid polyurethane foam, coatings, elastomers, in polyurethane foaming systems, isocyanate first reacts with triethylenediamine to form an active complex, the nature of the complex is very unstable, once the carbamate After the ester bond is formed, it will be released, which is conducive to further catalysis. Triethylenediamine has a strong catalytic effect on the gel reaction and the foaming reaction, especially on the polyurethane and the hydroxyl group. A33 is mainly used as a gel catalyst for polyurethane foams, and is widely used in soft, semi-rigid, rigid polyurethane foams, elastomers, and coatings.
