DESMOPHEN 670 BA

DESMOPHEN 670 BA is a slightly branched hydroxyl-bearing polyester that provides excellent flexibility and weather stability when combined with common polyurethane curing agents. As a co-reactant primarily with Desmodur® N 75 and ultra N 3390, DESMOPHEN 670 BA yields highly durable coatings formulated to withstand demanding outdoor environments. Its balanced properties allow formulating flexible, yet tough protective finishes for a wide range of substrate materials. Combined with the right hardener system, coatings developed using DESMOPHEN 670 BA exhibit high performance in terms of gloss retention, color fastness and resistance to chemicals, making it suitable for applications that require protection from the elements for many years.
