Main Use
1. A silane coupling agent containing active isocyanate functional groups. The isocyanate group exhibits the chemical characteristics of typical alkyl isocyanates and can easily interact with active hydrogen in organic polymers (such as Hydroxyl, amine, sulfhydryl, etc.) react, and the alkoxy groups provide good adhesion to the substrate after hydrolysis, or cross-link each other;
2. It can be used as a cross-linking agent in one-component moisture-curable polyurethane to cap glycols or polyether polyols;
3. Adhesion promoter for silicone adhesives or coatings to enhance their adhesion, water resistance, and weather resistance;
4. Silicone-modified hydroxypolyether is the key material for the production of STPU.
