Copper Stick Epoxy Putty COPPER-STICK Epoxy Repair Putty is a hand knead-able, copper-reinforced epoxy putty that mixes in one minute to provide fast, permanent repairs to pipes, tanks and vessels made of copper, brass, bronze and other non-ferrous metals. It comes in a handy rod form with the curing agent encapsulated in the contrasting colour base material. Its putty-like consistency eliminates drips and runs providing “no mess” application with no tools required for use. It bonds to damp, wet and slowly leaking surfaces. It contains no solvents, is non-toxic and will not shrink after cure. After full cure it can be drilled, filed, tapped, sanded, painted and machined. Has a simulated copper colour after cure. Directions for Use: In order to achieve optimum adhesion surfaces should be cleaned free from grease, dirt. Scuffing or sanding the surface prior to cleaning helps ensure a good bond. Mixing - twist or cut off the required amount. If the material is cold mixing may be difficult and warming to room temperature is advised. Apply to the surface to be repaired (within 2 minutes of mixing.) The mixed epoxy does not exhibit high bond strength at this point, but appears to be merely lying on the surface. Force into any cracks or holes to be filled and strike off excess material, preferably with tools wetted with clean water. When applying to a damp, wet, or slowly leaking area, work the material forcefully into the surface and apply pressure until adhesion begins to take effect. For a smooth appearance of the cured compound, hand rub with water or a damp cloth prior to hardening. Remove excess material before hardening begins. After 5-10 minutes the epoxy will harden like metal and start to form a tenacious bond. After just 2-3 hours it is completely cured and it can be drilled, sawn, carved, sanded, stained, or painted. Repaired parts can be put back into service once the repair is fully cured.
