Visbella® RTV Silicone Gasket Maker is a premium neutral, non sag acetoxy curing paste engineered for high temperature sealing applications. This versatile automotive RTV silicone cures into a permanently flexible silicone rubber when exposed to atmospheric moisture at room temperature, offering exceptional resistance to weathering, moisture, vibration, and UV light.


This RTV silicone gasket maker is heat stabilized to perform flawlessly in both freezing and high heat environments. It maintains flexibility and sealing integrity in engine bays, exhaust systems, and high temperature piping, making it ideal for automotive and industrial applications.
Once cured, the silicone rubber remains permanently flexible, accommodating vibration, thermal expansion, and contraction without cracking or losing seal quality. It stays stable even after prolonged exposure to harsh conditions, ensuring long term reliability.
It bonds strongly to a wide range of substrates, including glass, metal (steel, aluminum, copper), wood, painted surfaces, silicone rubber, and most plastics. This versatility eliminates the need for multiple sealants, simplifying repairs and maintenance.
Formulated to resist automotive fluids such as engine oil, transmission fluid, and antifreeze, it prevents leaks and maintains sealing performance in critical components like engines and gearboxes. It’s impervious to fluid immersion, ensuring durable protection against leaks.
The neutral, low odor formula is safe for use on sensitive materials and won’t cause corrosion or discoloration. The non sag paste consistency ensures easy application—even on vertical or overhead surfaces—without dripping, providing precise, mess free sealing.
With a tack free time of just 3–5 minutes and a cure rate of 4.0mm per 24 hours (at 22°C, 40%–60% R.H.), it speeds up repair processes. Once fully cured, it offers long lasting sealing that withstands years of use, reducing the need for rework.
Perfect for replacing or repairing engine gaskets (valve covers, oil pans, timing covers). It creates a leak proof seal that withstands high engine temperatures and oil exposure, ensuring optimal engine performance.
Ideal for sealing joints in industrial piping systems that transport hot fluids or gases. It maintains integrity under extreme heat, preventing leaks and ensuring safe, efficient operation.
Suitable for sealing carburetors, fuel injectors, and fuel lines. Its resistance to gasoline and other fuels makes it a reliable choice for preventing fuel leaks and maintaining fuel system efficiency.
Used to seal gearbox covers, transmission pans, and differential housings. It resists transmission fluid and handles the vibration and heat of these components, ensuring leak free operation.
Designed for motorcycle engines and components, it withstands the high temperatures and vibration of motorcycle operation. It’s ideal for sealing engine cases, exhaust joints, and other critical parts.
Suitable for sealing components in industrial machinery (pumps, compressors, generators) that operate under high heat or harsh conditions. It provides durable sealing against fluids, dust, and moisture.
