Abstract:
A useful composition for forming protective coatings for metallic equipment, said coating composition comprising:1) a natural-origin solvent, in the range of 25-95% by weight of the final formulation, said natural-origin solvent being a solvent derived from citrus fruit or pine tree processing, possessing approximately 95% by weight d- and/or d-l limonene, and 2) a natural-origin or naturally-derived resin as the major hardening component, comprising from about 5% to about 50% by weight of the final formulation, said resin being gilsonite, and 3) a naturally-derived plasticizer/softening agent such that the plasticizer to naturally-derived resinous material ratio is in the range of the range of 1 part plasticizer to 20 parts naturally-derived resinous material, to about 1 part plasticizer to 1 part naturally-derived resinous material, and the plasticizer is non-drying, said naturally-derived plasticizer/softening agents being a mixture of substantially non-drying fatty acid triglycerides, obtained from one of the natural-product processing industries, said triglyceride being an alkyl ester, wherein the fatty acids attached to glycerine are those that are produced by the plant or animal making the triglycerides.
