Abstract
The disclosure relates to temporary corrosion resistant coatings and films upon metal substrates, e.g., metal tools and dies. The temporary coatings and films will not adversely chemically alter the surface of the underlying substrate. The coatings/films comprise a mixture of at least one of an acrylic, water, an oil, silica, at least one silicate, surfactants and optionally one or more buffering materials and waxes.
Claims22
A composition comprising a combination comprising at least one synethetic oil and at least one biodegradable oil selected from the group consisting of castor oil, canola oil, sunflower oil, linseed oil, corn oil and soybean oil;
- at least one silicate, and at least one wax selected from the group consisting of paraffinic, microcrystalline and amber.
A composition comprising soybean oil, at least one silicate, at least one wax and silica.
A composition for use in reducing corrosion of a metallic surface obtained by combining at least one non-toxic oil, at least one synthetic oil, silica;
- and at least one wax selected from the group consisting of paraffinic, microcrystalline and amber.
A coating composition for use in reducing corrosion of a metallic surface, said composition comprising:
- a carrier medium capable of forming a coating upon a metallic surface;
- a corrosion inhibiting amount of a corrosion inhibitor wherein said inhibitor comprises at least one of silica and silicate;
- at least one surfactant;
- at least one wax selected from the group consisting of paraffinic, microcrystalline and amber;
- and wherein the carrier medium comprises at least one non-toxic oil and at least one synthetic oil.
A composition comprising at least one synthetic oil and biodegradable oil selected from the group consisting of castor oil, canola oil, sunflower oil, linseed oil, corn oil and soybean oil;
- at least one silicate, at least one wax and at least one propellant selected from the group consisting of carbon dioxide, butane, propanes and acetone;
- and combinations thereof.
