DESMODUR PL 340 BA/SN

DESMODUR PL 340 BA/SN is a blocked aliphatic polyisocyanate based on IPDI. It is suitable for use in combination with polyol components for the formulation of lightfast one-component polyurethane stoving coatings. DESMODUR PL 340 BA/SN can be combined with suitable, preferably flexible, Desmophen grades to formulate one-component polyurethane stoving coatings which are lightfast and resistant to weathering and chemicals and highly resistant to thermal yellowing. These coatings are used for original automotive topcoats. Compared with polyisocyanates blocked with butanone oxime, DESMODUR PL 340 BA/SN allows a reduction in stoving temperature of approximately 10°C, with no decrease in solvent and chemical resistance. DESMODUR PL 340 BA/SN provides benefits such as lightfastness, weathering and chemical resistance, and resistance to thermal yellowing which are highly desirable for long lasting coatings used in various applications.
