Room Temperature Vulcanizing Silicones Technical Information
RTV (Room Temperature Vulcanizing) Silicones can aggressively adhere to and readily release from most surfaces. They are also good for sealing, filling spaces between surfaces and gasketing. They adhere to rigid and flexible substrates including metal, glass, fiberglass (fiberglass reinforced panels), cement, canvas, rubber, plastic, ceramics and wood. Since they don′t run, they′re good for vertical and overhead applications.
One-Component RTV’s require no mixing and vary in viscosity. They have high fuel and oil resistance, high tensile strength, excellent electrical insulation and low volatility. Acetoxy Cure Silicone Sealants are excellent for use in construction and industrial applications due to their high and low temperature stability. They cure by reaction to moisture in the atmosphere. Alkoxy Neutral Cure Silicones offer exceptional adhesion and are non-corrosive to most metals. They are typically used on substrates in contact with fuel, solvents and chemicals.
