BAYHYDUR BL 2867

BAYHYDUR BL 2867 is a reactive, blocked, aliphatic polyisocyanate that can be used for the formulation of water-reducible, lightfast one-component polyurethane systems. BAYHYDUR BL 2867 was developed as a hardener for water-reducible, lightfast one-component polyurethane coatings. It provides flexibility, impact strength and adhesion when used in combination with polyols. The degree of crosslinking and the choice of the polyol component influence the properties of coating films. Areas of application for BAYHYDUR BL 2867 include automotive OEM coatings and high-grade industrial coatings for electronic devices, parts and accessories where durability, flexibility and adhesion are important. BAYHYDUR BL 2867 crosslinks as a function of the degree of crosslinking and the reaction partner. It provides benefits such as slight thermal yellowing resistance, water solubility and compatibility in coating formulations depending on the application needs.
