AQUEOUS LUBRICANT AND SURFACE CONDITIONER FOR FORMAQUEOUS LUBRICANT AND SURFACE CONDITIONER FOR FORMED METAL SURFACES ED METAL SURFACES

摘要

A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying sai d metal surfaces at a lower temperature. The conditioner includes (i) a water-soluble organic material selected from amine oxides and quaterna ry ammonium salts, ethoxylated castor oil derivatives, a nd imidazoline moiety-containing phosphonates and preferably also includes (ii) at least one of fluozirconate, fluohafnate, or fluotita nate ion, and (iii) phosphate and/or nitrate ions. Good resistance to damaging the fri ction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.
