Applications

Silane is a valuable addition for various uses, including:

1. Silane-Endcapped Polyurethanes: Silane-terminated polyurethanes can be created by combining traditional NCO-terminated urethane prepolymers with NQ-351. It reacts quickly with free isocyanate groups, resulting in a high-quality silane-endcapped product while minimizing side reactions.

2. The recommended silane for endcapping Polyurethanes. It produces clear, low-viscosity PU prepolymers with improved UV stability and reduced yellowing tendency in sealants.

3. Glass Fiber/Glass Fabric Composites: Used as a finish or size constituent.

4. Mineral Fiber Insulating Materials and Abrasives: Used as an additive to phenolic resin binders.

5. Foundry Resins: Used as an additive to phenolic, furan, and melamine resins.

6. Sealants and Adhesives: Used as a primer or additive and for chemical modification.

7. Mineral-Filled Polymers (Composites) or HFFR Cables: Used for pretreatment of fillers and pigments.

8. Paints and Coatings: Used as an additive and primer to improve adhesion to the substrate, as well as a primer for glass and metal.
