The disclosed technology relates to corrosion- or rust-preventive coating compositions and methods of their use. The compositions comprise a rust preventative composition, optionally including a diluent, and a quaternary ammonium salt.

Using quaternary amine additives to improve water separation

The disclosed technology relates to corrosion or rust preventive coating compositions and methods of their use. The compositions comprise a rust preventative composition, optionally including a diluent, and a quaternary ammonium salt.

A coating composition comprising an oxidized &#x3b1;-olefin having 16 to 40 carbon atoms and one or more carboxylic acid or ester groups; a hydrocarbon-soluble ester-containing polymer having at least one branch of 10 to 36 carbon atoms and having a number average molecular weight of 5000 to 300,000; a carboxylic acid of at least 10 carbon atoms; a salt of an alkylarylsulfonic acid; an oil in an amount sufficient to dissolve said metal salt; and optionally, a volatile diluent, provides good rust protection.

Oxidized alpha-olefins in rust preventive coatings

A coating composition of a first triglyceride having a melting point of at least 35&#xb0; C.; a second triglyceride having a melting point of less than 35&#xb0; C.; a hydrocarbon-soluble ester-containing polymer; a carboxylic diacid or polyacid having at least 10 carbon atoms; and a metal salt of an alkylarylsulfonate in a hydrocarbon oil, provides good rust protection.

Hydrogenated natural oils in rust preventative coatings

The invention relates to corrosion inhibitors, and more specifically corrosion inhibitors for coating compositions. The invention provides for coating compositions that have improved corrosion properties, including reduced flash rust during the application of the coating composition to a metal surface, and even improved corrosion inhibition in the resulting dried coating. The invention also provides for methods of making and using the described the compositions and the corrosion inhibitors thereof.
