DESMODUR PL 350 MPA/SN is a blocked aliphatic polyisocyanate based on HDI. It can be combined with polyol components for formulating lightfast one-component polyurethane stoving coatings. DESMODUR PL 350 MPA/SN allows reduction in stoving temperature of approx. 10°C compared to polyisocyanates blocked with butanone oxime, with no decrease in solvent and chemical resistance. This enables energy savings during curing. It also provides excellent weatherability and lightfastness to coatings. DESMODUR PL 350 MPA/SN has good compatibility with common solvents and polyols used. It can be thinned to different solids content for spray or other applications. Coatings formulated with DESMODUR PL 350 MPA/SN exhibit high mechanical strength, chemical resistance and durability required for demanding exterior applications.
