Desmophen® 670 BA
Covestro (formerly Bayer MaterialScience) 科思创
Desmophen® 670 BA is a slightly branched hydroxyl-bearing polyester that is used as a co-reactant primarily with Desmodur® N 75 and N 3390, which yields films with very good weather stability and excellent low temperature flexibility. Such coatings are mainly used to coat plastics and are force-dried, e.g. at 80°C. Desmophen® 670 BA can also be added to other two-component polyurethane systems to improve their flexibility. This product has a flash point of approx. 32°C, an acid value of 1.8±1mg KOH/g, and a non-volatile content (1g resin/1h 125°C, convection oven) of 80±1%.
