Product Introduction
Momentive SNAPSIL™ RTV229B is the B-component used in combination with RTV210A to create the fast-curing RTV210 silicone adhesive system. When mixed at the recommended ratio, the formulation cures rapidly at room temperature to form a tough, resilient silicone rubber with strong adhesion to metals, plastics, and glass. RTV229B enhances the paste-like, non-sag consistency of the mixed adhesive, making it suitable for vertical and overhead applications while maintaining excellent durability, electrical insulation, and environmental resistance.
Momentive SNAPSIL™ RTV229B Features
- Essential B-component of the RTV210 silicone adhesive system
- Very fast curing when blended with RTV210A
- Provides primerless adhesion to many substrates
- Low odor and non-corrosive to metals and plastics
- Strong electrical insulation properties
- Excellent resistance to chemicals, ozone, and weathering
- Suitable for thicker bond lines due to two-component cure mechanism
- Thixotropic consistency suitable for overhead and vertical applications
Momentive SNAPSIL™ RTV229B Applications
- Rapid curing in high-speed industrial bonding
- Automotive lighting assembly and component sealing
- Solar panel and industrial structure assembly
- Electronics and electrical components requiring non-corrosive silicone adhesion
- Bonding metals, glass, rigid plastics, and silicone rubber
- Vertical or overhead applications requiring non-sag adhesive
