Triethylenediamine (TEDA) 33% Solution TEDA A33(DPG/DEG) CAS 280-57-9

Triethylenediamine (TEDA) 33% Solution TEDA A33(DPG/DEG) CAS 280-57-9

TEDA A33, also known as Triethylenediamine (TEDA) 33% solution, is a highly efficient polyurethane catalyst widely used in rigid and flexible polyurethane foam systems. It is a balanced amine catalyst solution typically composed of 33% Triethylenediamine (TEDA) dissolved in a carrier solvent (commonly dipropylene glycol).

TEDA A33 provides excellent catalytic activity for the reaction between isocyanate and polyol, while also accelerating the blowing reaction between isocyanate and water, making it an essential catalyst for achieving uniform cell structure, good dimensional stability, and improved foam performance.
