A Novel Reactive UV-Absorbing Diol
The clearcoat enamel with crosslinking chemistries of isocyanate/polyol or melamine/polyol is the outermost layer of automotive coatings. It provides the topcoat layer excellent physical properties and a high-gloss appearance. To achieve long-term durability, UV stabilizers play an important role in protecting topcoats from color fading and surface cracking as a result of sunlight exposure. A novel benzotriazole (BTZ) UV absorber carries two primary hydroxyl groups, which can react with isocyanates and melamine resins and covalently bond with the polymer backbone. This advanced technology overcomes the migration issue and dramatically improves the coatings performance to levels that were otherwise unattainable.
