K-KAT 4205	Zirconium	1.0 - 2.0	SB	Selective Catalyst (less gassing). Good pot life. Recommended for 2K PU coatings.
K-KAT 5218	Aluminum	1.0 - 2.0	SB	Excellent 2K urethane pot life when used with 2,4 pentanedione
K-KAT XK-635	Zinc Complex	0.1 - 0.5 (2K PU) 0.5 - 1.0 (blocked NCO)	SB, SL	Effective replacement for tin catalysts, with good balance of cure/pot life in 2K PU. Effective with MEKO blocked isocyanate. Good hydrolytic stability.
K-KAT XK-651	Bismuth Carboxylate	0.1 - 0.5% (2K PU) 1.0 - 2.5% (blocked NCO)	SB	Versatile bismuth carboxylate catalyst designed for blocked isocyanate, two component urethanes and one and two component silane terminated coatings. Improved hydrolytic stability.
Waterborne 2K PU
K-KAT XK-614	Zinc Complex	0.25 - 1.0	SB, WB	Most versatile. Effective in 2K WB and blocked isocyanate systems. Great hydrolytic stability. For use in polyol component.
K-KAT 6212	Zirconium	0.3 - 2.0	SB, WB	Selective catalyst for SB and WB 2K PU coatings. Sensitive to moisture, include in isocyanate component or as 3rd component.
K-KAT XK-661	Metal Complex	0.25 - 1.0	SB, WB	A novel non-tin catalyst recommended for 2K solvent based and 2K waterborne polyurethanes, as well as, for 1K blocked isocyanate systems.
Cast Elastomer 2K PU
K-KAT XK-604	Mixed Carboxylate	0.1 - 1.0	SB	Very good gel profile in ambient cure 2K urethane elastomer systems. Alternative to mercury.
K-KAT XK-617	Mixed Carboxylate	0.1 - 1.0	SB	Excellent gel profile. Slightly less selective than XK-604.
K-KAT XK-618	Mixed Carboxylate	0.1 - 1.0	SB	Best gel profile compared to mercury, with induction period followed by snap cure. Best compatibility in 1,4-butanediol.
