Features and uses:

Used in the production of rigid isocyanate foams. 

K-15 is a solution of potassium-salt in diethylene glycol. It promotes the isocyanate reaction and is used in a wide range of rigid foam applications. For better surface curing, improved adhesion and better flow alternatives, consider TMR-2 catalysts.

K-15 is an excellent and cost-effective isocyanate catalyst. Its high conversion rate has established it as the catalyst of choice in a number of rigid applications.


Storage Information 

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.
