Product Introduction
Momentive SNAPSIL™ RTV6445 is a one-component, heat-curable silicone adhesive sealant engineered for primerless adhesion to a wide variety of substrates. It features a white, thixotropic paste consistency that allows application on vertical and overhead surfaces without slump. With a long working time at room temperature and rapid cure at elevated temperatures, SNAPSIL™ RTV6445 provides robust mechanical strength, excellent dielectric performance, and stable operation across broad temperature conditions.
Momentive SNAPSIL™ RTV6445 Features
- One-component heat-curable silicone adhesive, no mixing required
- Fast curing at elevated temperatures for efficient processing
- Primerless adhesion to many metals, plastics and other substrates
- Low linear shrinkage and no cure by-products
- Non-corrosive to metals and sensitive components
- Excellent dielectric strength and electrical insulation properties
- Outstanding performance over a wide thermal range
- White, thixotropic paste suitable for vertical and overhead applications
Momentive SNAPSIL™ RTV6445 Applications
- Adhesive bonding and sealing for electronic and electrical components
- Vertical and overhead joints where non-sag behavior is required
- High-temperature bonding processes in industrial assemblies
- Sealing and encapsulation where non-corrosive, primerless adhesion is desired
- General-purpose heat-cure silicone adhesive applications
