Desmodur N 3790 BA is an aliphatic polyisocyanate (high functional HDI trimer).
It is suitable for use as the hardener component for lightfast, rapid-drying polyurethane coating systems.
It is suitable for use as the hardener component for lightfast, rapid-drying polyurethane coating systems.
储存条件
Desmodur N 3790 BA 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.
