| Characterization: Slightly branched hydroxyl-bearing polyester. As a co-reactant primarily with Desmodur® N 75 and N 3390 in the formulation of weather-stable flexible coatings. Properties / Applications: Combined with Desmodur® N 75 or N 3390, Desmophen® 670 BA 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.
