RTV408 is a neutral cure, medium modulus silicone sealant that cures to a tough, flexible rubber when exposed to moisture. It features primerless adhesion to: aluminum, stainless steel, chromium, tin, iron, plastics, rigid PVC, phenolic resin, glass, ceramic and most reflective-coated glasses. Its fast cure time and easy tooling make it ideal for many in-house production applications. It is non-corrosive to most building materials such as glass (including insulating glass), tiles, and sanitary equipment. It is also used in vehicles, ships, aircraft, as well as for electrical insulation. RTV408 does not cause corrosion in contact with metals. It is suitable for alkaline materials such as mortar and cement, and other applications where metal corrosion could be a problem. RTV408 stays flexible and is resistant to cracking or becoming brittle in a wide range of temperatures approximately -65 to +400 degrees Fahrenheit (-18 to 204 degrees Celsius). In order to help you better select the correct sealant, we have put together a Silicone and Sealant Selector Chart. You need to have Adobe Acrobat Reader installed in order to view this chart.
