BAYHYDUR BL 2781

BAYHYDUR BL 2781 is a water-thinnable, aliphatic, blocked polyisocyanate that provides improved flexibility, impact strength and adhesion properties when used in formulations. As an additive, BAYHYDUR BL 2781 enhances the performance of conventional aqueous systems. It offers advantages over other blocked polyisocyanates by not requiring a cosolvent. BAYHYDUR BL 2781 was developed as a hardener for water-thinnable, lightfast, one-component coatings. When crosslinked within its recommended temperature range, it helps deliver durable, weather-resistant coatings with resistance to yellowing. Suitable for a variety applications including metal substrates and composites, BAYHYDUR BL 2781 allows formulating coatings with optimized properties tailored for demanding exterior exposure conditions.
