Product Introduction
Momentive SNAPSIL™ RTV5813 is a one-component, neutral-cure silicone adhesive sealant that forms a tough, durable elastomer upon exposure to atmospheric moisture. With fast initial adhesion development and excellent confined-cure characteristics, RTV5813 supports improved production efficiency. It adheres well to metals, rigid plastics, glass, ceramics, and silicone surfaces while providing outstanding electrical insulation and long-term environmental stability.
SNAPSIL™ RTV5813 Features
- One-component, neutral-cure silicone with no mixing required
- Fast curing with strong initial adhesion buildup
- Excellent confined-cure performance
- Primerless adhesion to metals, plastics, glass, ceramics, and silicone rubber
- Non-corrosive cure suitable for sensitive substrates
- Strong UV, chemical, and weather resistance
- High mechanical durability including tear, tensile strength, and elongation
- Superior electrical insulating properties
- Effective in bead thicknesses up to 6 mm
- Flexible across a wide temperature range from -75°F to 400°F
SNAPSIL™ RTV5813 Applications
- Bonding and sealing in confined or hard-to-reach spaces
- Electrical insulation and component protection
- Industrial assemblies requiring rapid handling
- High-temperature bonding applications
- General-purpose sealing across metals, plastics, and glass
- Equipment and appliance manufacturing requiring strong adhesion
