K-KAT XK-604

K-KAT XK-604 is an effective catalyst for the reaction of isocyanates and polyols with hydroxyl groups used in the production of cast elastomers. It is a proprietary mixed organometallic complex specially formulated to be an alternative to mercury catalysts without the toxicity concerns.

ADVANTAGES:
Excellent cure response
Similar cure profile to mercury catalysts
Environmentally more acceptable
