Desmodur N 3800 is an aliphatic polyisocyanate (flexibilizing HDI trimer).
It is suitable for use as the hardener component for lightfast polyurethane coating systems.
It is suitable for use as the hardener component for lightfast polyurethane coating systems.
储存条件
Desmodur N 3800 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. Due to the raw materials used, the product can occasionally exhibit temperature-dependent turbidity. This turbidity can be reversed by thinning with solvents or heating carefully to maximum 50°C without adversely affecting the quality of the product. Recommended storage temperature is 0º-30ºC.
