ABSTRACT:
The improved coating of the present invention provides a protective coating for pipe, tubular shapes, other metal members, and metal structures. The protective coating comprises a polymer concrete, which is preferably a mixture of an organic resin, a filler material and a chemical activator. The organic resin is preferably a mixture of thermosetting polymer resins, such as bisphenol A based epoxy, bisphenol A based epoxy blended with polyglycol di-epoxide, and polyglycol di-epoxide. The filler material may be calcium carbonate, silica flour, zeosphere, talc, or kaolin, and preferably is of up to 200 mesh in size. The chemical activator preferably is an amine, such as aminoethylpiperazine or tetraethylene pentamine. The protective coating may be prepared by the process comprising the steps of combining and then heating the organic resin and filler material, mixing the organic resin and filler material with the chemical activator to create a polymer concrete, spraying the polymer concrete on the metal member or structure, and protecting the sprayed polymer concrete for a polymerization period.
