Patent number: 6294597Abstract: A curable polymeric composition which is a liquid at 20° C. and which comprises 25 to 60% by weight of a resin component which comprises an epoxy, 5 to 25% by weight of a curing agent which comprises two components, a first component which is a cycloaliphatic amine or an aromatic amine, and a second component which is a polyamide amine, and 20 to 65% by weight of an inert inorganic filler. The curable composition can be used in a method of protecting a substrate such as a pipe or a pipe joint from corrosion or mechanical damage. In the method, the curable composition is first applied to the substrate, a polymeric covering layer is applied over the curable composition with an innermost layer of a heat-activatable sealant in intimate contact with the curable composition, and the curable composition is then cured. During the curing process, the heat-activatable sealant, e.g. a hot melt adhesive, remains in contact with the curable composition and interacts therewith.Type: GrantFiled: August 4, 1997Date of Patent: September 25, 2001Inventors: James Rinde, George Pieslak, Leon C. Glover

Patent number: 6015600Abstract: An article (2) in which at least part of a surface (8) of a polymeric element has an embossed pattern (6). The article may be either heat-recoverable or non-heat-recoverable. If the article is heat-recoverable, when heated the article recovers and the embossed surface becomes substantially smooth. The change in surface texture can be used to indicate that sufficient heat has been applied to the article to achieve adequate recovery and/or to adequately melt an attached adhesive layer (10). In another embodiment, the article (2) is in the form of a patch (14) which can be used to secure the opposing longitudinal edges of heat-recoverable article which is in the form of a wraparound sheet.Type: GrantFiled: August 26, 1997Date of Patent: January 18, 2000Inventors: Walter J. Greuel, Jr., George Pieslak, Efrain Renteria, Stanley Simpson, Jan L. Vansant, Barnie A. Wallace, Jr.

Patent number: 4997685Abstract: The invention relates to a method for applying a protective coating to a substrate, such as metallic pipe, which comprises applying onto the substrate a liquid curable polymeric composition capable of curing to a substantial extent within about 24 hours at less than about 80.degree. C., then applying one or more polymeric layers, the innermost of which is capable of interacting with said curable composition, and permitting the composition to cure. In certain embodiments the polymeric layer is applied as a polymeric article, in other embodiments a multiple layer polymeric covering is applied over the curable composition.Type: GrantFiled: August 25, 1989Date of Patent: March 5, 1991Assignee: Raychem CorporationInventors: George Pieslak, Tony G.

Patent number: 4533419Abstract: A patch closure system for joining heat recoverable sheet material, especially for covering a substrate where the joined material is to be recovered around the substrate, comprises a layer of adhesive on one surface, a part of which is a pressure-sensitive adhesive and the remainder of which is a heat-activatable adhesive. The pressure-sensitive adhesive layer is of such an area and is placed such that, when the patch is placed over the overlap between the edges of the heat recoverable sheet material, the patch will continue to cover the overlap when the sheet material is recovered, even if the heat-activatable adhesive layer has not been used to attach the patch to the sheet material.Type: GrantFiled: September 15, 1984Date of Patent: August 6, 1985Assignee: Raychem CorporationInventors: George Pieslak, Barnie A.

Patent number: 4455204Abstract: An adhesive composition comprises an adhesive component and a hydrazine derivative. The adhesive composition has improved resistance to cathodic disbonding when used to adhere a protective coating, such as a polymeric layer, to the surface of a metal substrate. Cathodic disbonding is observed when an electric current is impressed through the substrate to reduce corrosion by inhibiting loss of metal ions from the substrate.Type: GrantFiled: May 21, 1982Date of Patent: June 19, 1984Assignee: Raychem CorporationInventors: George Pieslak, Elena C. Fritchle

Patent number: 4287034Abstract: A protective coating adhered to the surface of a metal substrate such as a pipe using an adhesive composition containing an adhesive component and a polyhydroxy compound protects the substrate from corrosion. The adhesive has improved resistance to cathodic disbonding which generally weakens the adhesive bond between the protective coating and the substrate when a current is impressed through the substrate causing it to function as a cathode. The electric current inhibits loss of metal ions from the substrate to the environment thus reducing corrosion of the substrate.Type: GrantFiled: November 9, 1979Date of Patent: September 1, 1981Assignee: Raychem CorporationInventors: George Pieslak, Kathleen A. Erbes-Mrsny, Elena C. Fritchle
