Patent number: 6426129Abstract: An adhesive rubber article of the type having a release liner covering its tacky, adhesive surface to prevent the adhesive rubber article from adhering to various substrates or to itself prior to its intended use includes an impression or mark presented on one or more surfaces for facilitating the alignment and application of the adhesive rubber article on one or more substrates. The release liner has been scored, perforated or otherwise cut in a longitudinal direction of the article such that the scoring of the release liner further produces a visual guide on the adhesive rubber article. Thus, upon removal of the release paper, the guide may be used to align and apply the adhesive rubber article to the various substrates. These adhesive rubber articles are particularly useful within the roofing industry for bonding panels of rubber membranes together or for use as flashing.Type: GrantFiled: March 9, 1998Date of Patent: July 30, 2002Assignee: BFS Diversified Products, LLCInventors: Joseph J. Kalwara, Daniel L. Barksdale

Patent number: 6071996Abstract: A walkway pad composition comprises 100 parts by weight of an ethylene-propylene-diene terpolymer; from about 60 to 700 parts by weight of a filler selected from the group consisting of reinforcing and non-reinforcing materials and mixtures thereof, per 100 parts of the terpolymer; from about 40 to 175 parts by weight of a processing material and mixtures thereof, per 100 parts of the terpolymer; and from about 2 to 10 parts by weight of a cure package, per 100 parts of the EPDM terpolymer, the composition being devoid of any additional polymeric components. The 100 percent EPDM walkway pad composition has better low temperature properties and superior weathering resistance, and heat aging resistance compared to other walkway pad compositions which may include other polymeric components such as natural rubber, synthetic polyisoprene, styrene-butadiene rubber (SBR), polybutadiene, and butyl (IR) rubber. Up to about 25 parts by weight of ethylene-propylene copolymers may be substituted for the EPDM terpolymers.Type: GrantFiled: August 8, 1997Date of Patent: June 6, 2000Assignee: Bridgestone/Firestone, Inc.Inventors: James A.
