type:

       Hydrophilic aliphatic isocyanate curing agent based on hexamethylene diisocyanate for two-component systems for coating adhesives.

Features/Applications:

PU-2655 is a crosslinking agent suitable for waterborne systems; such waterborne systems need to have good bonding stability and chemical resistance.

Although the curing agent is relatively weak in hydrophilicity, it is easy to emulsify in the aqueous phase, even under the low shear forces commonly found in commercial use. Coatings prepared with this product form high gloss, low haze films.

Generally, when mixed with hydrophilic curing agent, especially ionic hydrophilic polyol dispersion, it can be diluted with water in advance or add a small amount of organic co-solvent to control the viscosity increase. Due to its moderate balance of hydrophilicity and high functionality, waterborne two-component polyurethane coatings prepared using PU-2655 are characterized by fast drying, rapid hardening, and films with high final hardness and excellent chemical resistance characteristics.
