General Characterization:
Desmodur PL 350 MPA/SN is a blocked aliphatic polyisocyanate based on HDI.
It is suitable for use in combination with polyol components for the formulation of lightfast one-component polyurethane stoving coatings.
Storage Conditions:
Desmodur PL 350 MPA/SN should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Recommended storage temperature is 0º-30ºC.
