Jenolite Copper Epoxy Putty Stick is a two component epoxy resin stick, that can be used to repair pipes, tanks, hot pipes and vessels made of brass, copper, bronze and other non ferrous metals. Ideal for plumbing elbows, sink taps and water heaters. Will also seal freeze breaks in pipework. The hand-mixable, fast-setting epoxy putty forms a durable bond that after mixing creates a polymer compound that can be moulded to fit. Once fully cured it is completely waterproof and can be sanded and painted over.
