Title:
TREATMENT LIQUID FOR IMPROVING FORMABILITY OF ALUMINUM ALLOY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/040096
Kind Code:
A1
Abstract:
Disclosed is a treatment liquid for improving formability of aluminum alloy materials which forms a coating film when applied onto the surface of an aluminum alloy material and dried thereon. The coating film covering the aluminum alloy material exhibits excellent lubricating effects when the coated aluminum alloy material is subjected to a forming process. Specifically disclosed is a treatment liquid for improving formability of aluminum alloy materials, which contains a water-soluble urethane resin, a water-soluble polyester resin, a water-soluble acrylic resin, a water-soluble epoxy resin, and one or more of resins obtained by modifying those organic resins. The treatment liquid may further contain, in addition to the above-mentioned resins, a silane coupling agent, a colloidal silica, a lubricant, a metal alkoxide, a heat resistance-imparting agent and the like.
