Adhesion Promoter for Architectural Coatings

Adhesion promoters for architectural coatings are organosilane or polymer-based additives that improve the bonding of water-based and solvent-based coatings to challenging substrates including glass, metal, concrete, and previously painted surfaces. They function by forming covalent or hydrogen bonds between the coating binder and the substrate, significantly improving wet and dry adhesion performance. These additives reduce the risk of paint delamination and blistering in exterior and high-humidity applications.
