Patent number: 7928157Abstract: This invention relates to a tire with a tread of a rubber composition which contains zinc rosinate within and on the surface of said rubber composition. Said zinc rosinate promotes enhanced wet traction for said tire tread by actually replacing a more conventional zinc stearate for a tire tread rubber composition. Said zinc rosinate is a product of a combination of rosin acid and zinc oxide formed in situ within said rubber composition. Said more conventional zinc stearate is a product of a combination of stearic acid and zinc oxide formed in situ within a tread rubber composition.Type: GrantFiled: September 10, 2007Date of Patent: April 19, 2011Assignee: The Goodyear Tire & Rubber CompanyInventors: Paul Harry Sandstrom, Joseph Kevin Hubbell, Thomas Charles Lippello, III

Patent number: 7897070Abstract: A composition for improving the heat reflectivity and the heat resistance of a metal substrate. The coating composition comprises a latex resin including acrylic polymers; silica; and a fire retardant including at least one of a phosphated pentaerythritol ammonium salt, an organo-polyphosphate ammonium salt, an ammonium salt, and a Magnesium salt. The silica reflects and resists heat. Additionally, the silica raises the decomposition temperature of the resin by insulating the resin from heat and reflecting heat away from the resin. This, in turn, increases the ability of the composition to maintain its bond to the substrate at high temperatures. As such, the coating remains on the substrate where it reflects and resists heat, i.e., it does not easily brush or rub off after several hours of exposure to high heat. The silica can be rice hull silica.Type: GrantFiled: May 15, 2007Date of Patent: March 1, 2011Assignee: Envirotrol, Inc.Inventors: James Joseph Knocke, Al Beatty, Thomas R. Sharp
