Conclusion Conform to the enterprise standard
HMDI is similar in chemical structure to 4,4'-diphenylmethane diisocyanate, and it replaces the benzene ring with a cyclohexyl six-membered ring. It is an alicyclic diisocyanate. It can be used to produce non-yellowing polyurethane products, which is suitable for production Polyurethane materials with excellent light stability, weather resistance and mechanical properties, especially suitable for the production of polyurethane elastomers, water-based polyurethanes, fabric coatings and radiation-cured polyurethane-acrylate coatings. In addition to excellent mechanical properties, HMDI also gives products outstanding excellent hydrolysis resistance and chemical resistance.
