SELLEYS AUTO FIX Marine Sealant Silicone RTV Clear 75g

Selleys Autofix Marine Sealant is a translucent, neutral-curing RTV silicone formulated for the demanding conditions of marine environments. It cures to a tough, flexible, permanently waterproof seal with excellent adhesion to glass, fibreglass, painted and varnished wood, most plastics, and most metals — resisting UV, salt spray, detergents, vibration, and weather.

Supplied in a 75g tube (Clear/Translucent), this sealant handles temperatures from -60°C to +180°C continuously (+240°C intermittently), making it ideal for sealing gaps, joints, hatches, windows, fittings, and instruments on boats and marine vessels. It also insulates and waterproofs electrical connections and locks nuts, bolts, and plates against vibration. Full cure in 24 hours for standard applications; up to 7 days when used as a gasket or adhesive.
