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.
