Patent number: 5691019Abstract: A coated article for foul release for use in aquatic applications does not require a discrete tie-layer to ensure adhesion of a coating to a substrate. An adhesion promoting layer comprising an anticorrosive material and a bonding agent is applied directly to the substrate. A release layer comprising organopolysiloxane is deposited onto the adhesion promoting layer. A method for applying the foul release coating comprises the following steps: applying an adhesion promoting layer, curing the adhesion promoting layer, applying the release layer and curing the release layer.Type: GrantFiled: May 1, 1995Date of Patent: November 25, 1997Assignee: General Electric CompanyInventors: Kenneth Michael Carroll, Owen Maynard Harblin, Slawomir Rubinsztajn

Patent number: 5662978Abstract: There is provided herein a protective cover made from conjugate fiber nonwoven fabric having a basis weight between about 1 and 8 osy laminated with a film. The conjugate fibers may be in a configuration such as sheath/core, side-by-side and islands in the sea and may be formed from polyolefins and polyamides. The preferred fiber embodiments are a side-by-side polypropylene-polyethylene fiber and a sheath/core polyethylene/nylon 6 fiber. The fabric is preferably extrusion coated with a polyethylene film to form the protective cover. The cover is light weight, waterproof and provides sufficient burst and tensile strength so that the cover may be used during transportation of, for example, a boat.Type: GrantFiled: September 1, 1995Date of Patent: September 2, 1997Assignee: Kimberly-Clark Worldwide, Inc.Inventors: J. Page Brown, Ty J. Stokes
