Momentive·Silane Coupling Agent
- Product Description
Silane coupling agents are also known as adhesion promoters. They are used as coupling agents, crosslinking agents and surface modifiers in paints, coatings, adhesives and sealants.
Main features:
1. Better resistance to abrasion
2. Enhanced dry and wet adhesion on various substrates
3. Better corrosion resistance and chemical resistance
4. Higher hardness and mechanical strength
