Industrial and Construction Silicone

Crafted with a focus on user-friendliness, this CRL RTV408 Silicone sealant boasts a wide range of impressive features. Firstly, it is a neutral cure, medium modulus silicone sealant that cures to a tough, flexible rubber upon exposure to moisture. Noteworthy is its primerless adhesion to a variety of materials, including aluminum, stainless steel, chromium, tin, iron, plastics, rigid PVC, phenolic resin, glass, ceramic, and most reflective-coated glasses.

The sealant's fast cure time and easy tooling make it an ideal choice for numerous in-house production applications. Importantly, it is non-corrosive to most building materials, such as glass (including insulating glass), tiles, and sanitary equipment, and can also be used in vehicles, ships, aircraft, and for electrical insulation. It does not cause corrosion in contact with metals and is suitable for alkaline materials like mortar and cement, where metal corrosion could be a concern.

Remarkably, CRL RTV408 maintains its flexibility and resists cracking or becoming brittle over a wide temperature range, from approximately -65 to 400 degrees Fahrenheit (-54 to 204 degrees Celsius). This versatility allows for application in outdoor temperatures as low as -20°F (-29°C), provided that the surfaces are clean, dry, and frost-free, or on surfaces as high as 100°F (38°C).

To further enhance the user experience, the sealant cartridges are packed with innovative Screw-On Nozzles, offering a greater yield per tube. These nozzles are four inches (ten centimeters) long and tapered, allowing users to trim the nozzle to the exact bead size they require.

Notably, the CRL RTV408 Silicone sealant meets or exceeds the Federal Specifications TT-S-001543A (COM-NBS) Class A for silicone building sealants and TT-S-00230C (COM-NBS) Class A, making it compatible for Insulating Glass Glazing. Additionally, it is AAMA (American Architectural Manufacturers Association) approved, ensuring its quality and performance.

In summary, this CRL RTV408 Silicone sealant combines a low-odor, non-acetic cure formula with excellent adhesion to most surfaces, easy gunnability and tooling, and a 20-year limited warranty. Its versatility, performance, and user-friendly features make it a compelling choice for a wide range of applications.
