Core Features


100% Silicone Composition for High Temp Performance

Made with 100% silicone, Visbella® RTV Silicone GREY 32G offers exceptional high temperature resistance, withstanding intermittent exposure up to 315°C (600°F). This makes it ideal for applications in engines, exhaust systems, and high temperature piping, where generic sealants would degrade or fail. The pure silicone formulation ensures thermal stability and long term reliability even in extreme heat, a critical feature for automotive and industrial use.


Neutral Acetoxy Curing for Room Temperature Application

This RTV silicone features a neutral acetoxy curing formula that cures at room temperature upon contact with atmospheric moisture. The curing process is hassle free, requiring no additional heat or pressure, making it accessible for DIY enthusiasts and professionals alike. Once cured, it forms a permanently flexible silicone rubber that adapts to thermal expansion and contraction, preventing seal cracking or failure due to temperature fluctuations.


Exceptional Adhesion to Diverse Materials

Visbella® RTV Silicone GREY 32G exhibits strong adhesion to a wide range of substrates, including glass, metal, wood, painted surfaces, silicone rubber, and some plastics. This versatility eliminates the need for multiple sealants, as it reliably bonds different materials in various applications—from automotive engine gaskets to household repairs. The strong adhesion ensures a leak proof seal that withstands vibration and pressure, even in high stress environments.


Superior Resistance to Weathering & Environmental Stress

This weather resistant sealant offers outstanding protection against UV light, moisture, weathering, and vibration. It maintains its integrity in harsh outdoor conditions, making it suitable for both indoor and outdoor applications. Whether exposed to rain, sunlight, or extreme temperature changes, the seal remains intact and effective, reducing maintenance needs and extending the lifespan of sealed components.


Permanent Flexibility & Pressure Resistance

Unlike rigid sealants that crack under stress, Visbella® RTV Silicone GREY 32G remains permanently flexible after curing. This flexibility allows it to accommodate movement, vibration, and thermal expansion, ensuring a long lasting seal in dynamic environments like engines or industrial machinery. It’s also pressure resistant, making it ideal for applications where seals are subjected to mechanical pressure or fluid pressure, such as piping systems and gearboxes.


Sensor Safe Design for Vehicle Applications

Equipped with a sensor safe design, this RTV silicone is safe to use in automotive applications near sensors, electronics, and other sensitive components. It does not emit harmful fumes or corrode delicate parts, making it a reliable choice for modern vehicle engines, where sensor compatibility is non negotiable.


Applications


Engine & Motor Gasket Sealing

Visbella® RTV Silicone GREY 32G is perfect for sealing engine and motor components, including valve covers, oil pans, timing covers, and intake manifolds. Its high temperature resistance and pressure resistance ensure a leak proof seal that withstands the heat and vibration of engine operation. The sensor safe design makes it compatible with modern vehicle engines, providing peace of mind for mechanics and car enthusiasts.


High Temperature Piping Systems

This high temperature RTV silicone is ideal for sealing joints in high temperature piping systems, such as exhaust pipes, industrial steam pipes, and heating ducts. It withstands extreme heat and prevents leaks, ensuring efficient and safe operation of piping systems in industrial facilities, commercial buildings, and residential homes.


Carburetors & Gearboxes

Carburetors and gearboxes require reliable seals to prevent fluid leaks and maintain performance. Visbella® RTV Silicone GREY 32G provides a flexible, durable seal that adapts to the movement and pressure of these components. It resists oil, fuel, and other automotive fluids, ensuring long term sealing effectiveness and reducing the risk of equipment damage due to leaks.


Industrial Machinery Seals

In industrial settings, this sealant is used to seal joints in machinery, pumps, compressors, and other equipment. Its resistance to vibration, moisture, and temperature fluctuations makes it suitable for heavy duty industrial applications. It helps prevent leaks of oils, coolants, and other fluids, reducing maintenance costs and minimizing downtime for critical machinery.


Household & DIY Sealing Projects

Beyond industrial and automotive use, Visbella® RTV Silicone GREY 32G is also suitable for household DIY projects. It can be used to seal gaps around windows, doors, sinks, and bathtubs, providing a waterproof and weather resistant seal. It’s also ideal for repairing small appliances, toys, and other items that require a flexible, durable seal, making it a versatile addition to any toolbox.



Technical Parameters


As a waterproof sealant, it provides long lasting protection against weathering, moisture, vibration, and UV light, ensuring leaks are prevented and equipment remains operational. Designed for professionals and hobbyists alike, Visbella® RTV Silicone GREY 32G is the go to choice for reliable, flexible, and pressure resistant seals that stand the test of time.
