一般特征

Desmodur BL 3370 MPA is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).
It is suitable for use in combination with Desmophen® grades to formulate lightfast, one-component stoving polyurethane coatings with high resistance to thermal yellowing; as an additive in conventional stoving coating systems to improve the reactivity, flexibility and adhesion.

储存条件

Desmodur BL 3370 MPA 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.
