## Abstract

The present invention provides metal shaping compositions and processes for using same for shaping metal substrates. Specifically, the metal shaping composition discussed herein are environmentally-friendly, water-containing composition which provide excellent lubricity under metal shaping process conditions while also providing excellent rust protection. The metal shaping compositions discussed herein contain (i) a film-forming lubricant capable of being solubilized into water in dispersible or emulsifiable form and which softens at a temperature of about 80 to about 200° C.; (ii) a film forming polymeric binder capable of being solubilized into water in dispersible or emulsifiable form; (iii) a solid lubricant capable of being solubilized into water in dispersible or emulsifiable form; and (iv) a corrosion inhibitor.

## Claims

### Claim 1

An aqueous composition comprising:
(i) about 5 to 32% by weight of a film-forming lubricant comprising a polyethylene emulsion capable of being solubilized into water in dispersible or emulsifiable form and which softens at a temperature of about 80 to about 200° C. and having an average particle size of 0.001 to 1.5 μm;
(ii) about 5 to 15% by weight of a film forming acrylic-based polymeric binder capable of being solubilized into water in dispersible or emulsifiable form;
(iii) about 10 to 50% by weight of a solid lubricant comprising a metal stearate capable of being solubilized into water in dispersible or emulsifiable form; and
(iv) about 0.5 to about 10% by weight of a corrosion inhibitor; and
(v) the balance water;
wherein said components are at least 90% emulsified when combined in a liquid medium and wherein said composition functions to maintain a thin lubricating film under metal shaping process conditions.
