application

Trimethyl hydroxyethyl ethylenediamine is a non-spray amine catalyst for promoting urea (isocyanate-water) reaction, and because it contains an active hydroxyl group, it is easy to react into the polymer matrix;

Trimethyl hydroxyethyl ethylenediamine can be used in soft and rigid polyurethane systems which require smooth reaction characteristics.
