Chem-Set RTV118 Self-Leveling Silicone Rubber Tube, 10.1 oz

Description

RTV118 Silicone is a self-leveling silicone rubber sealant supplied in a 10.1 fl oz tube for sealing, coating, and thin-section potting work. Its flowable body is useful when a paste sealant cannot reach small crevices, narrow gaps, or hard-to-access areas.

RTV118 Silicone Benefits

• Self-leveling consistency helps the material flow into tight areas before cure.
• One-component packaging keeps setup simple because there is no mixing or metering step.
• Room-temperature moisture cure supports bench, repair, and production use.
• Flexible cured rubber handles low temperature movement and high temperature service demands.
• Weathering, ozone, chemical resistance, and electrical insulation properties support industrial sealing work.

This product fits jobs where the bead needs to settle into a thin section rather than hold a tall vertical shape. Use it for coating, filling small surface voids, sealing around parts, and protecting assemblies where a flowable silicone is the right fit.

RTV118 Silicone Applications

• Thin-section potting and small void filling.
• Self-leveling protective coatings over prepared surfaces.
• Sealing crevices and hard-to-reach areas in assemblies.
• General silicone rubber sealing where a flowable product is preferred.
• Electrical insulation work where the application allows acetoxy-cure silicone.

Surface Preparation and Use

Apply to clean, dry surfaces free of oil, dust, release agent, and loose material. Because this is a moisture-curing silicone, avoid deep sections that exceed the data sheet guidance for one-part RTV cure depth.

Use enough material to wet the area without flooding nearby parts. Allow the silicone to skin and cure under normal room-temperature humidity before moving the assembly into service.

Technical Details and Documentation

Published RTV100-series data identifies RTV118 as a one-component, ready-to-use, self-leveling silicone sealant that cures to resilient silicone rubber on exposure to atmospheric moisture. For broader adhesive and sealant background, review the Adhesive and Sealant Council.
