NT CAT A-1 is a tertiary amine which has a strong influence on the urea (water-isocyanate) reaction in flexible and rigid polyurethane foams. It consists of 70% bis(2-Dimethylaminoethyl) ether diluted with 30% dipropylene glycol.
NT CAT A-1 is a strong blowing catalyst that can be used in a wide range of polyurethane foams, including flexible molded, semi-flexible, polyether slabstock and low-density spray foams.
It has a strong catalytic effect on the blowing reaction and can be balanced by the addition of a strong gelling catalyst such as Crystalline or 33-LV catalysts.

Recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30 °C. Lower and higher storage temperatures are not preferable and should be avoided.
