HDI-based Polyisocyanates

What are HDI-based Polyisocyanates?
High weatherability, low viscosity and low temperature curability that contribute energy saving and lowering VOCs.

Quick Drying Polyisocyanate
Fast Dry Polyisocyanate

Fast drying polyisocyanate is based on the widely used aliphatic hexamethylene-1,6-diisocyanate (HDI) – enhanced to dry polyurethane faster. These are primarily used for high performance, fast drying polyurethane applications to improve weatherability and UV/chemical resistance.

Low and Ultra-low Viscosity HDI-based polyisocyanates

Low Viscosity HDI-polyisocyanates
Polyisocyanate based on the widely used aliphatic hexamethylene-1,6-diisocyanate (HDI). These are primarily used for high performance coatings applications to improve weatherability and UV/chemical resistance.

These low and ultra low viscosity grades have 100% symmetrical chemical structure enabling better performance compared to competitors which have slight biuret contamination. The higher quality is great for non-solvent formulations and enables better surface smoothness and gloss retention.
