LOCTITE SI 596 Red is an acetoxy-cure RTV silicone sealant used for high-temperature gasketing and sealing in automotive and industrial applications.
This sealant is widely applied as a formed-in-place gasket in automotive systems such as valve covers, oil pans, water pumps, and intake manifolds. It is also suitable for sealing and assembly work in industrial furnaces, ovens, boilers, exhaust systems, and high-temperature ducting. Designed for applications up to 315 °C, LOCTITE SI 596 Red supports both OEM production and plant maintenance where reliable high-temperature sealing is required.
Easy application without mixing
Maintains seal integrity under heat
Reduces vibration-related joint stress
Suitable for formed-in-place gasket designs
Reliable performance in maintenance and OEM use
Good temperature resistance for demanding environments
LOCTITE SI 596 Red is a one-component RTV silicone sealant designed for high-temperature gasketing and sealing applications in automotive and industrial environments. It is based on acetoxy silicone technology and cures at room temperature when exposed to moisture in the air, forming a flexible and durable silicone rubber seal.
The product is supplied as a red, thixotropic paste that stays in place after application and reduces material flow on vertical or overhead surfaces. Once cured, it enhances load-bearing capacity and absorbs vibration and shock in the sealed joint. LOCTITE SI 596 Red offers good temperature resistance and is commonly used in demanding sealing conditions.
