VESTANAT® H12MDI is a cycloaliphatic diisocyanate. It is a low-viscosity liquid with a characteristic odor. Due to its cycloaliphatic structure, this product is a suitable raw material for the manufacture of polyurethanes exhibiting light stability, weatherability and mechanical properties. VESTANAT® grades are aliphatic diisocyanate monomers for light stable PUR systems and polyisocyanate crosslinkers for high performance PUR coatings.
