一般特征

Desmophen 670 BA is a slightly branched, hydroxyl-bearing polyester.
It is suitable as a co-reactant primarily with Desmodur® N 75A and N 3390A BA/SN in the formulation of weather-stable flexible coatings.

储存条件

Desmophen 670 BA should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Under certain conditions (temperatures below 15°C, long storage) the product may become cloudy. It can be completely rehomogenized by heating to around 40°C or adding solvent, and can be further processed without any loss of quality. Recommended storage temperature is less than 30ºC.
