Wurth RTV Black Silicone Instant Gasket Maker High Temperature Sealant 200ml

For sealing applications in motor vehicles, Wurth Super RTV Silicone Black is a modified oxime silicone supplied in a 200 mL format. This high-grade adhesive and sealing compound is suited to components including water pumps, oil pumps, front covers, cam shaft bearing covers, thermostat bodies, oil pans, gear box covers, power axle covers, sun roofs and doors.

Its acid-free hardening system is non-corrosive and non-conductive, with very good resistance to chemicals including motor and gear oils, refrigerants and anti-freeze. The product is supplied in a compressed air spray can for controlled, even bead application. Best adhesion is achieved on clean, dry surfaces, with old sealing material removed fully before use.
