PU-655 Hydrophilic Aliphatic Isocyanate Curing Agent

type :

Hydrophilic aliphatic isocyanate curing agent based on hexamethylene diisocyanate, Two-component system for paint binders.

Features /app:

PU-655 is a cross-linking agent suitable for water-based systems; Water-based systems need to have the characteristics of good combination stability and chemical resistance.

Although the hydrophilicity of the curing agent is relatively weak, it can , easy emulsification even under low shear conditions commonly found in commercial applications. Coatings prepared using this product form high gloss, low haze films.

Generally with hydrophilic curing agent, especially ionic hydrophilic polyol When the dispersion is mixed, it can be pre-diluted with water or add a small amount of organic co-solvent to control the viscosity increase. Due to the balance between moderate hydrophilicity and high functionality, waterborne two-component polyurethane coatings prepared using PU-655 have the characteristics of fast drying and fast curing, and the formed film has high final hardness and excellent chemical resistance characteristics.
