Title:
AQUEOUS COOLANT FOR THE DI FORMING OF LAMINATED METAL SHEETS AND PROCESS FOR THE DI FORMING OF LAMINATED METAL SHEETS
Document Type and Number:
WIPO Patent Application WO/2009/145338
Kind Code:
A1
Abstract:
An aqueous coolant for the DI forming of laminated metal sheets, which contains (a) at least one base selected from among alkanolamines and alkali metal hydroxides, (b) fatty acid, and (c) water, wherein the total content of the base (a) and the fatty acid (b) is 0.02 to 4mass% and straight-chain fatty acids having 6 to 12 carbon atoms account for 80 to 100mass% of the fatty acid (b). The coolant can bring excellent DI formability to laminated metal sheets and do no damage to the films of the laminates metal sheets. Further, the coolant is easy to wash away, so that DI cans having high food safety can be obtained even when the step of washing products of DI forming is simplified.
