K-15 is normally a solid, usually dissolved and diluted with diethylene glycol to form a solution;

K-15 is suitable for use in high-viscosity polyol formulations to promote isocyanate reaction, with high activity;

K-15 is widely used in spraying rigid foam, PIR rigid foam and various other PU rigid foams.

Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse


200KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing. Maintain good hygiene habits.

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.
