一般特征
Desmodur N 3900 is a low-viscosity, aliphatic polyisocyanate resin based on hexamethylene diisocyanate (HDI).
It is used as the hardener for weather-stable coating systems.
It is used as the hardener for weather-stable coating systems.
储存条件
Desmodur N 3900 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture. 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.
