METAL PRODUCT SURFACE-TREATED WITH ALKALI-SOLUBLE LUBRICATING FILM EXHIBITING EXCELLENT FORMABILITY AND EXCELLENT FILM REMOVAL PROPERTY BEING STABLE FOR A LONG TIME AND INDEPENDENT OF TEMPERATURE FOR DRYING FILM |
摘要 |
<p>In order to provide an alkali-soluble-film surface-lubricated metal product excellent in moldability and long-term stable film-removability independent of the film drying temperature, an alkali-soluble lubricating film mainly comprising an alkali-soluble polyurethane aqueous composition containing a polyether polyol as a skeleton and also containing a carboxyl group within the molecule, and a lubricating function-imparting agent in an amount of 1 to 30 mass% based on the alkali-soluble polyurethane aqueous composition is coated on both surfaces or one surface of a metal to have a film thickness of 0.5 to 10 mu m, thereby constituting an alkali-soluble-film surface-lubricated metal product excellent in moldability and long-term stable film-removability independent of the film drying temperature, wherein the elastic modulus of the film after coating is from 0.5 to 20 GPa at 25 DEG C.</p> |
