K-KAT 4205

K-KAT 4205 is a zirconium chelate complex that is an effective catalyst for high solids 2-component urethane coatings. It is effective for ambient and low temperature cure systems.

ADVANTAGES:
Fast tack free time
Excellent viscosity stability/pot life
Effective at low metal concentrations
Effective with a variety of isocyanates and polyols
 

TYPICAL PROPERTIES:
Appearance:                             Clear, colorless liquid 
Volatile:                                     2, 4-pentanedione
Specific gravity, 25°C:              0.97 g/ml    
 

SOLUBILITY:
Soluble in esters, ketones and aromatic hydrocarbons.
 

APPLICATIONS:
2-component urethane coatings for:
Automotive topcoats
High performance maintenance coatings
Aerospace coatings
Coatings for structural plastics
 

TYPICAL USAGE LEVELS:
1.0 - 2.0 % on total resin solids. For best results, it is recommended that an equal amount of 2, 4 - pentanedione or solvent be removed from the formulation prior to adding K-KAT 4205.
