33% Triethylenediamine & 67% Ethylene Glycol

Overview

This catalyst is a solution of 33% triethylenediamine (TEDA) in 67% ethylene glycol (EG). It is mainly used in polyurethane shoe-sole and elastomer systems in which ethylene glycol acts as a chain extender.

Also known as

33% TEDA in ethylene glycol; TEDA/EG catalyst
