33% Triethylenediamine & 67% 1,4-Butanediol

Overview

This catalyst is a solution of 33% triethylenediamine (TEDA) in 67% 1,4-butanediol (BDO). Because BDO is also a chain extender, it suits elastomer and shoe-sole systems in which the catalyst carrier should react into the polymer.

Also known as

33% TEDA in 1,4-butanediol; TEDA/BDO catalyst

CAS number

280-57-9 (TEDA); 110-63-4 (1,4-butanediol)
