Use nCordobond Steel Putty repairs tears, holes, cracks, flaws and other defects in steel and other metals. nIt also adheres to wood, pottery etc. Metal parts that are treated with Cordobond are extremely nresistant to corrosion. Corroded mortises can be filled with Cordobond Steel Putty. After hardening they can nbe re-drilled or mortised. Extra reinforcement can be achieved by covering the material with Cordobond nResin and glass fibre. n nComposition nCordobond Steel Putty consists of three components, Resin and Activator and carborundum, each packaged nseparately. The Resin tin is partially filled so that the Activator can be added and mixed together. nDuring mixing it is important to add small portions of carborundum. n nMixture nIt is important that Cordobond Steel Putty is mixed together well; otherwise it will not fully harden.
