Patent number: 6991851Abstract: A dry-strippable coating composition can be incorporated into a composite article and comprises a dried water-borne polyurethane dispersion including a release additive comprising a releasing co-solvent or other selected release material. When water is removed from the polyurethane dispersion of the composite article and when the article comprises a thermoformable substrate, the article can be thermoformed to provide a shaped article. Dry-stripping the coating composition from the substrate provides a thermoformed substrate and a thermoformed protective layer. The dry-strippable coatings provide temporary protection for the surface of various products and components during manufacture, assembly, shipping, installation, painting, and refinishing operations.Type: GrantFiled: April 2, 2003Date of Patent: January 31, 2006Assignee: 3M Innovative Properties CompanyInventors: Larry R. Krepski, Kevin M. Lewandowski, Daniel E. Mickus, Susan K. Rowen, Stephen A. Johnson

Patent number: 6139594Abstract: An abrasive article is provided that includes a tie coat which improves adhesion between an abrasive layer and a backing in the abrasive article. The tie coat is preferably formed from a tie coat precursor comprising a sulfopoly(ester-urethane) component comprising in its backbone at least one non-terminal arylene or alkylene group comprising a pendant sulfonic acid group or salt thereof having the formula: ##STR1## wherein R is a trivalent aliphatic or aromatic group and M is a cation, said aliphatic or aromatic group being bonded directly to ester groups and wherein the polymer is terminated by at least one hydrolyzable silyl group. Preferably, the abrasive article is a structured abrasive article. Also provided is a method for making an abrasive article.Type: GrantFiled: April 13, 1998Date of Patent: October 31, 2000Assignee: 3M Innovative Properties CompanyInventors: Don H. Kincaid, Scott R. Culler, Larry R. Krepski, Daniel E. Mickus
