General Characterization

Desmodur VP LS 2371 is an aliphatic polyisocyanate prepolymer based on isophorone diisocyanate (IPDI).
It is suitable as a binder for elastic coatings and surface sealing compounds.

Storage Conditions

Desmodur VP LS 2371 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture and should therefore be stored in its sealed original containers. Storage at elevated temperatures results in polymerisation with a subsequent reduction in the NCO content and an increase in viscosity. Recommended storage temperature is at room temperature, approximately 23ºC.
