Krylon W11124510 Silicone Rubber Sealant Rtv Aluminum 10 Oz

Product Description

The KRYLON W11124510 is an all-purpose silicone rubber sealant (RTV) designed for sealing, bonding, and waterproofing applications across a wide range of trade and industrial uses. Supplied in a 10 oz cartridge in an aluminum finish color, this room-temperature-vulcanizing silicone cures to a flexible, durable seal that resists moisture, vibration, and temperature cycling. It is well suited for HVAC, plumbing, and general mechanical applications where a reliable, long-lasting bead is required. Licensed trades and experienced DIYers alike rely on RTV silicone for gasketing and sealing tasks that demand flexibility after cure.

This sealant is appropriate for use in both residential and light commercial settings. Common applications include sealing ductwork penetrations, plumbing fixtures, electrical enclosures, and general construction joints. The aluminum color finish makes it a practical choice where a neutral, metallic-toned bead is acceptable or preferred. It is intended for use on metal, glass, ceramic, and most non-porous substrates encountered in trade work.

Key Features

• Room-temperature-vulcanizing (RTV) silicone formulation cures to a flexible, permanent seal
• Aluminum color finish blends with metal surfaces and mechanical components
• 10 oz cartridge size compatible with standard caulking guns
• Resists moisture, vibration, and thermal expansion and contraction
• All-purpose formulation suitable for metal, glass, ceramic, and non-porous substrates

Compatibility

Designed as an all-purpose RTV silicone sealant for general trade use on non-porous surfaces including metal, glass, and ceramic in HVAC, plumbing, and mechanical applications.

Installation Notes

Surface preparation is critical for silicone adhesion — clean all surfaces thoroughly and remove oil, dust, and loose material before applying the bead. Apply with a standard caulk gun and tool the bead immediately before a skin forms. Allow full cure time before exposing the joint to moisture or mechanical stress. Follow all applicable local building and mechanical codes for sealant use in HVAC and plumbing systems.
