Product Description

 

Application

Used as an important additive for many applications. Examples are:
1. Silane-endcapped Polyurethanes: Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers with NQ-351. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced.
2. The most recommended silane for endcapping Polyurethanes. It leads to colorless low-viscosity PU prepolymers with improved UV stability and reduced yellowing tendency of sealants.
3. Glass fiber/glass fabric composites: As a finish or size constituent
4. Mineral fiber insulating materials and abrasives: As an additive to phenolic resin binders
5. Foundry resins: As an additive to phenolic, furan and melamine resins
6. Sealants and adhesives: As a primer or additive and for chemical modification
7. Mineral-filled polymers (composites) or HFFR cables: For pretreatment of fillers and pigments
8. Paints and coatings: As an additive and primer for improving adhesion to the substrate. As a primer for glass and metal.
