Description
High-Temperature RTV Silicone Sealant for Industrial & Automotive Applications
High-Temperature Performance
Engineered to withstand continuous operating temperatures of up to 300°C, making it suitable for demanding heat-exposed applications.
Room Temperature Vulcanizing (RTV) Formula
Single-component sealant cures naturally with atmospheric moisture, eliminating the need for mixing or heating.
Flexible & Durable Seal
Forms a tough, elastic rubber seal that resists cracking, vibration, and thermal expansion.
Excellent Multi-Surface Adhesion
Bonds effectively to metal, glass, ceramics, aluminum, and many other common industrial and automotive materials.
Professional Industrial Solution
Ideal for engine components, exhaust systems, gearboxes, pumps, ovens, furnaces, industrial machinery, automotive repairs, and high-temperature sealing applications.
