Covestro DESMODURE® PL 350 MPA/SN Polyurethane
Categories:	Polymer; Thermoset; Polyurethane, TS
Material Notes:	Characterization: Blocked aliphatic polyisocyanate based on HDI. In combination with polyol components for the formulation of lightfast one-component polyurethane stoving coatings. Properties / Applications: Combined with suitable Desmophen® products, Desmodur® PL 350 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 allows a reduction in the stoving temperature of approx. 10 °C, with no decrease in solvent and chemical resistance.
