ITW Permatex® Ultra Copper® RTV Silicone Gasket
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Permatex® Ultra Copper® is a single component, room temperature vulcanizing gasketing compound designed to provide reliable “formed-in-place” gaskets for mechanical assemblies. This material cures on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. The product resists aging, weathering and thermal cycling without hardening, shrinking or cracking. Designed for the higher temperature environments encountered in 4-cylinder, turbocharged, and high performance engines. Permatex Ultra Copper is the most advanced high performance, high temperature (up to 700°F (371°C) intermittent) RTV gasket available. OEM Specified. Permatex ® Ultra Copper ® Hi-Temp RTV Silicone Gasket cures on exposure to moisture in the air. The product dries tack free in one hour and fully cures in 24 hours. Cure times will vary with temperature, humidity and gap. It retains effective properties in contact with automotive fluids, such as motor oil, transmission fluids, alcohol and antifreeze solutions. Note: Not recommended for parts in contact with gasoline. Information provided by ITW Performance Polymers.
