Abstract
A biocidal wax composition for preventing corrosion and biological fouling nd surface degradation of submerged structures comprises from about 10 to about 40 percent of total biocidal wax composition of a biocidal polymeric gel consisting of a polymer from the group consisting of a polyethylene, polypropylene, a copolymer of polyethylene and vinyl acetate, and mixtures thereof and a solvent selected from the group consisting of mineral oil, a paraffin wax and mixtures thereof, and a biocide; and from about 60 to about 90 percent of total biocidal wax composition of a wax matrix composition consisting of petrolatum, at least two chlorinated waxes, and a microcrystalline wax. The biocidal wax is prepared by shock-cooling a hot solution of a polymer through its cloud point, admixing a biocide with the gel, and admixing the above wax matrix composition with the gel.
