Abstract: Environmentally safe, cost effective, VOC-free compositions and methods for the prevention and treatment of corrosive processes in and on metal such as rust, flash rust and scale in a wide variety of industry sectors is provided. Compositions particularly well-suited for the long term prevention of rust and other corrosive processes may include an organic acid or salt thereof, a natural gum and/or wax and/or extracts or derivatives thereof, a gelling agent, and water.

Abstract: Environmentally safe, cost effective, VOC-free compositions and methods for the prevention and treatment of corrosive processes in and on metal such as rust, flash rust and scale in a wide variety of industry sectors is provided. Compositions particularly well suited for preventing and treating flash rust may include an organic acid or salt thereof, a natural gum and/or wax and/or wax extract, and water. Such compositions do not substantially affect the adhesive quality of coatings subsequently applied to the metal surface and provide excellent solvent and spray resistance.

Abstract: An aqueous non-toxic biorational or environmentally safe composition to reduce or inhibit corrosion, rust and scale on metal surfaces comprising effective amounts of sorbic acid, salts of sorbic acid and/or derivatives thereof and a variety of hydrocarbons, esters, acids, alcohols and/or saponified fatty acids or combinations thereof derived from beeswax, vegetable waxes and/or derivatives thereof.
