Product Introduction
Momentive SNAPSIL™ RTV5223 is a one-component, low-modulus, high-elongation silicone sealant designed for durable bonding and sealing across a wide range of substrates. It cures at room temperature by reacting with atmospheric moisture and releases a low-odor, non-corrosive by-product suitable for sensitive electronics. With excellent environmental resistance and strong mechanical flexibility, RTV5223 is ideal for assemblies that undergo significant movement or thermal expansion.
SNAPSIL™ RTV5223 Features
- One-component neutral-cure system requiring no mixing
- Low modulus and high elongation for dynamic joint movement
- Primerless adhesion to metals, plastics, paints, polycarbonate, and acrylic
- Non-corrosive cure suitable for electronic components
- Excellent tear resistance and durable mechanical performance
- Resistant to chemicals, ozone, moisture, and harsh weather
- UL recognized component – File E-36952
- Strong electrical insulation properties
- Room-temperature curing with low odor
- Retains elastomeric properties from -75°F to 140°F
SNAPSIL™ RTV5223 Applications
- Bonding and sealing of metals, ceramics, plastics, and glass
- Electrical and electronic systems requiring non-corrosive curing
- Multi-material assemblies with high movement or thermal expansion
- Outdoor and chemically exposed sealing environments
- General sealing requiring up to 3.2 mm (0.125 in) thickness
- Industrial applications needing flexible, durable silicone bonding
