General description

Poly(hexamethylene diisocyanate) (PolyHDI) is an aliphatic compound belonging to the class of isocyanates. It is generally prepared by reacting hexamethylene diamine with phosgene.

Application

PolyHDI can be used as a compatibilizer to increase the complex viscosity of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)/poly(lactic acid) biopolymer based blends. It can be used as a hardener that can be mixed with polyol resins to form polyurethane coatings with a wide range of applications like self-cleaning.
