International Classification:

A61C 3/03

US Classification:

433118, 132322

Abstract:

A power flosser tip incorporating a tooth-whitening coating. The coating is typically abrasive, and whitens teeth by scraping or wearing down hardened plaque or other tooth discolorations. The coating may also whiten teeth through a chemical reaction. The coating may be flavored in order to enhance user enjoyment. The coating is chemically bonded to the flosser tip, and dissolves when in contact with saliva or water at room temperature and pressure.

Abstract:

A silicone coating material is operative to graft a silicone polymer coating on an ignition wire. The ignition wire includes an insulated conductor with an inner conductive core and an outer insulating jacket layer which has an outer surface. The silicone coating material is applied to the outer surface of the insulating jacket layer and includes a silicone prepolymer, a coupling agent, a catalyst, and a graft initiator. The graft initiator is operative to prepare the outer surface of the insulating jacket to receive by grafting the coating layer including the silicone prepolymer and the coupling agent, and the catalyst is operative to promote grafting by polymerization of the coating layer.

International Classification:

C08G077/00

US Classification:

528/010000

Abstract:

A polymeric coating composition chemically grafts to cellulose or synthetics, and the resulting product serves as a filter in a filtration system which keeps the filtered liquid or gas clean by removing soot, solids, liquids and other contaminants, thus maximizing the life of equipment or engines. The coating is developed using chemical grafting that involves the use of monomers, prepolymers, catalysts, a graft initiator system and/or other ingredients. The resulting coating is used to treat cotton, other cellulose materials, synthetic materials and combinations thereof, and provides for graft-polymerization, thereby forming a polymeric film which is chemically bonded to the cotton fiber, other cellulose fibers, synthetics or combinations thereof with excellent adhesion, thereby imparting all the desired properties to the fiber in terms of increased filtration efficiency.

International Classification:

D02G 300

US Classification:

428318

Abstract:

A flavored toothpaste composition is bonded to the bristles of a disposable toothbrush by a process which involves the chemical grafting and polymerizing of selected monomers and prepolymers to the bristles via a free radical mechanism. This process locks in the flavor until the product can be utilized. When the toothpaste is brought into contact with an aqueous medium, such as saliva in the oral cavity, the toothpaste dissolves thereby releasing the desired flavor to the teeth and oral cavity.

Abstract:

The invention is in a conductive prepolymer composition which when polymerized and cured is used to coat a substrate material such as steel, stainless steel, iron, brass, copper, aluminum, platinum, titanium, silver, gold, Telfon, plastics, glass, or combinations thereof. It comprises: (a) from 25 to 99 parts by weight of a poly(amide-imide) prepolymer; (b) from 1 to 25 parts by weight of a trifunctional ester selected from the group consisting of trifunctional methacrylate ester, trifunctional acrylate ester, and mixtures thereof; (c) from 0. 5 to 15 parts by weight of an organo-reactive silane consisting of an amino group containing alkoxysilane having the formula NH. sub. 2 (CH. sub. 2). sub. n Si(OC. sub. 2 H. sub. 5). sub. 3, where n is an integer from 1 to 20; and (d) a conductive additive. The invention also provides polymer coated substrates having a tenaciously bound polymer layer which is corrosion resistant, has advantageous properties of conductivity and can be soldered.
