DESMOPHEN R-221-75

DESMOPHEN R-221-75 is a saturated polyester resin supplied in propylene glycol monomethyl ether acetate (PMA). It is useful in improving weatherability and flexibility of polyester systems reacted with polyisocyanates. DESMOPHEN R-221-75 provides enhanced durability and longer lifespan to coatings when used in polyester coating formulations reacted with polyisocyanates. It improves the weather resistance of coatings against environmental factors like sunlight, rain and temperature extremes. DESMOPHEN R-221-75 also enhances the flexibility of coatings, making them more durable against mechanical stresses and impacts. The improved properties of coatings and finishes formulated with DESMOPHEN R-221-75 help protect buildings and infrastructure from degradation for extended periods of time.
