When a thermally activated blowing agent is utilized, the resulting foam is remarkably uniform in cell structure and has improved strength and modulus. Hollow inorganic microspheres are employed to reduce the density of the thermoset produced from the two part system.Type: GrantFiled: October 10, 2001Date of Patent: September 17, 2002Assignee: Henkel CorporationInventor: Vettithara C.

Patent number: 6444718Abstract: Aqueous urea and/or aqueous urea condensate and/or aqueous urea composition may be utilized to fight grass, forest, building, and other flammable organic material by applying it to these flammable organic materials. The aqueous urea and/or aqueous urea condensate and/or aqueous composition may also be incorporated into flammable materials such as solid and foam plastic and natural materials. Aqueous urea composition are produced by adding and mixing carbon auxiliaries, such as phosphorus containing compounds, metal containing compounds that will accelerate carbonization, heat reflector, surfactant and fillers to the aqueous urea.Type: GrantFiled: September 1, 2000Date of Patent: September 3, 2002Inventor: David H. Blount

Patent number: 6423251Abstract: Aqueous urea condensate-boron oxyacid salts composition may be utilized to fight grass, forest, building, and other flammable organic material by applying it to these flammable organic materials. The solid or aqueous urea condensate-boron oxyacid salts composition may also be incorporated into flammable materials such as solid and foam plastic and natural materials. Urea condensate-boron oxyacid salts composition may also contain carbonization auxiliaries, such as phosphorus containing compounds, metal containing compounds that will accelerate carbonization, heat reflector, surfactant and fillers. The urea condensate-boron oxyacid salts composition is produced by mixing, heating and/or reacting urea, boron oxyacids and alkali metal hydroxide or alkaline earth metal hydroxide or oxide or the boron oxyacids maybe first reacted with the alkali metal hydroxide or the alkaline earth metal oxide or hydroxide.Type: GrantFiled: January 5, 2001Date of Patent: July 23, 2002Inventor: David H. Blount

Patent number: 6423758Abstract: A foam composition and method of making the same. The foam of the present invention comprises a mixture of glutarate ester plasticizer, adipate ester plasticizer, alcohol carboxylic acid ester, cell stabilizer, barium/zinc activator stabilizer, potassium/zinc activator stabilizer or zinc stabilizer, azodicarbonamide blowing agent, low-fogging vinyl dispersion resin, vinyl blending resin, and black acrylic pigment dispersion. The foam is made by the process of mixing the ingredients until a homogenous liquid mixture is present, de-airing the homogeneous liquid mixture, casting the liquid mixture on a non-fogging release-coated surface, expanding the cast liquid mixture by exposing it to an elevated temperature for a prescribed duration of time, and then either cooling the expanded mixture and winding it into rolls, or coating the stabilized composition with pressure sensitive adhesive, cooling it, and then winding it into rolls.Type: GrantFiled: June 25, 2001Date of Patent: July 23, 2002Assignee: Gaska Tape, Inc.Inventor: Lawrence A. Cascino
