Desmodur® PL 350 MPA/SN

Covestro (formerly Bayer MaterialScience) 科思创

Desmodur® PL 350 MPA/SN is a blocked aliphatic polyisocyanate based on HDI used in combination with polyol components for the formulation of lightfast one-component polyurethane stoving coatings. This product has a non-volatile content (0.2g/60 min./80°C) 75 ± 2%, a viscosity at 23°C 4,300 ± 1,500 mPa·s, and an equivalent weight of approx. 400. Combined with suitable Desmophen® products, Desmodur® PL 350 MPA/SN can be used in the formulation of weather-stable, lightfast, chemically resistant and highly heat-stable one-component polyurethane stoving coatings for use in automotive finishing. Compared with polyisocyanates blocked with butanone oxime, Desmodur® PL 350 MPA/SN allows a reduction in the stoving temperature of approx. 10°C, with no decrease in solvent and chemical resistance.
