RTV (Room Temperature Vulcanizing) silicone sealants are high-performance materials that provide strong adhesion and easy release on a wide range of surfaces. Ideal for sealing, gap filling, and gasketing applications, RTV silicones bond effectively to both rigid and flexible substrates, including:
Basics of Room Temperature Vulcanizing Silicones
RTV Silicone Sealants – High-Performance Adhesion and Versatility
- Metal
- Glass
- Fiberglass (fiberglass reinforced panels)
- Cement
- Canvas
- Rubber
- Plastic
- Ceramics
- Wood
These silicone sealants are non-sagging and non-running, making them suitable for vertical and overhead applications. Their reliable performance and material compatibility make RTV silicones ideal for industrial, automotive, construction, and general-purpose sealing needs.
One-Component RTVs
One-Component RTVs 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 that come in contact with fuel, solvents, and chemicals. Use the chart below to help make a product selection.
By Product | Corrosive | Best Adhesive Substrate | Odor | Tack-Free Time | Cure Rate | Optimum Temperature Range | |
ACETOXY CURE | Acetic Acid | Yes | Glass, Plastics, Most Metals | Yes | Fast | Fast | - 65°F - 400°F |
ALKOXY NEUTRAL CURE | Alcohol | No | Glass, Plastics, Most Metals | No | Moderate | Slow | - 75°F - 400°F |
