28182-81-2 - Introduction
polyhexamethylene diisocyanate is a polyisocyanate. Aliphatic diisocyanate compounds have irreplaceable advantages in the synthesis of anti-yellowing coatings and coatings, and are widely used in the coating industry. However, the low vapor pressure of aliphatic isocyanates as monomers makes them more limited in application, so it is more common to convert them into polyisocyanates by polymerization, which increases the tolerance during processing, products with excellent performance were further obtained.
