一般特征
Desmodur HL BA is an aromatic/aliphatic polyisocyanate based on toluene diisocyanate (TDI)/ hexamethylene diisocyanate (HDI).
In combination with various Desmophen® grades or other suitable substances containing hydroxyl groups to formulate clear or pigmented, two-component polyurethane coatings characterized by rapid drying and good lightfastness.
储存条件
Desmodur® HL 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 high temperatures leads to an increase in viscosity and a reduction of the NCO content. Recommended storage temperature is 0º-30ºC.
