K-KAT XK-626

 K-KAT XK-626 is an effective catalyst for the reaction of isocyanates and polyols for the production of urethanes. It is a proprietary mixed organometallic complex specially designed to be an alternative to mercury, tin and amine catalysts without the toxicity concerns. K-KAT XK-626 is formulated to meet the requirements of FDA 21 175.300.

ADVANTAGES:
Can be used in ambient, force dry and bake systems
Complies with FDA 21CFR 175.300
Environmentally acceptable
 

TYPICAL PROPERTIES:
Appearance:                                    Clear, light amber liquid
% Metal:                                          16.6
Specific gravity, 25°C:                     1.09 g/ml
 

SOLUBILITY:
K-KAT XK-626 is soluble in n-Butanol, ketones, glycol ethers, aromatic and aliphatic hydrocarbons. K-KAT XK-626 is also partially soluble in water.
 

APPLICATIONS:
K-KAT XK-626 is recommended for 2K and 1K blocked isocyanate coatings. K-KAT XK-628 can replace many heavy metal and/or toxic catalysts used in the production of urethane elastomers, foams and coatings.

TYPICAL USAGE LEVELS:
0.1 – 1.0% as supplied on total resin solids.
