Abstract
A useful composition for protecting metal equipment from corrosion and/or other damage comprises 1) gilsonite, which is a mined asphalt; and/or some other natural-origin or naturally-derived resin, 2) a naturally-derived solvent such as d-limonene and/or other terpenes, and 3) a naturally-derived non-drying plasticizer such as fatty acid triglycerides. 4) Optionally, additives for controlling rheology, viscosity, lubricity, corrosion rates etc. can be added to obtain specific properties which may be desirable. The invention also relates to a method of preventing corrosion or other damage to metal equipment by applying the above-mentioned coating to the equipment by spraying, rolling and/or brushing.
