NT CAT A-33 is a tertiary amine which has a strong influence on promoting the urethane reaction in a variety of flexible and rigid foam as well as CASE applications. It is a mixture of 33% triethylene diamine and 67% dipropylene glycol.
NT CAT A-33 is used in the manufacture of all types of polyurethane
foam. It can be used as a 3:1 replacement for Crystalline catalyst in all foam formulations. For example, 0.3 pphp NT CAT A-33 replaces 0.1 pphp Crystalline catalyst.

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.
