Abstract
Water-based stamping lubricants are comprised of: (1) water; (2) a polyester that is water-soluble or readily emulsifiable made by reacting one or more dicarboxylic acids and a polyalkylene glycol; (3) one or more ethoxylated alkylalcohols; (4) the salt of a phosphate ester of an ethoxylated alkyl alcohol; (5) an alkanolamine.
Claims22
An aqueous-based stamping lubricant composition comprising:
