Henkseal® Ultra Copper RTV Silicone Gasket Maker for Quick Repairs is a premium, high-temperature adhesive engineered for professionals and DIY enthusiasts who demand reliability in extreme conditions. Designed to withstand temperatures up to 700°F (370°C), this copper-infused formula creates durable, flexible seals that resist cracking, shrinking, and oil/fuel degradation. Whether you're repairing automotive engines, industrial machinery, or household equipment, this versatile sealant ensures leak-free performance and long-lasting protection. Traditional gaskets often fail under heat and pressure, leading to costly leaks and downtime. HENKSAL® Ultra Copper RTV Silicone solves this with its advanced silicone base and copper particles, which enhance thermal conductivity and adhesion. The result is a robust seal that bonds tightly to metal, plastic, and composite surfaces, even in high-vibration environments. Its sensor-safe, low-volatile formula ensures compatibility with oxygen sensors and catalytic converters, making it ideal for modern engines.
• Withstands Extreme Temperatures (Up to 700°F):Engineered for high-heat applications like exhaust systems and turbochargers, ensuring seals stay intact under stress.
•Multi-Surface Compatibility:Adheres to metals, plastics, and composites, with resistance to oils, fuels, and chemicals.
•Quick Curing & Easy Application:Precision nozzle allows controlled dispensing; cures rapidly to minimize repair downtime.
•Oil & Chemical Resistance: Withstands exposure to engine oils, coolants, fuels, and solvents without degrading.
•Non-Corrosive & Low Odor: Safe for use on aluminum, steel, and other metals; emits minimal fumes during curing.
