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.

Filtration media having germicidal for use in filtering particles and deactivating, removing and/or destroying microorganisms from a feed liquid passing through the media. The filtration media includes an effective amount of at least one germicidal agent associated to monomers polmerized and chemically grafted and covalently bonded to the surface of the media. The germicidal filter media is prepared by contacting the media with a grafting solution comprising one or more monomers, a catalyst, a surface agent, a curign agent, at least one graft initiator, and at least on germicide and subsequently curing the media at an elevated temperature to chemically graft the polmerizable monomers onto a surface of the media and associate at least one germicide thereto. Filter media suitable for use in the present invention include ceramic spheroids, hollow glass spheres, polmeric type meida, thermoset coated glass spheres, and crystalline microporous materials, such as zeolites. The germicidal filter media is effective for deactivating, destroying and/or removing from a feed liquid, such as water, escherichia coli, salmonella choleraesuis, staphylococcus, aspergsillus, klebisiella, listeria, clostridium, rotavirus, cysts and other microorganisms. Moreover, the filter media can be used repeatedly without a significant decrease in its germicidal effectiveness.

A solution for forming a graft substrate containing a graft initiator, a catalyst for activating the graft initiator, a polymerizable silicon softener, and at least one additional prepolymer, each of the softener and the prepolymer which includes a functional group for reaction with an activated site on the substrate for grafting thereto and water. The treated fiber exhibits excellent crockfastness, color fastness, and abrasion resistance, strength, and has a soft hand.

Surface modified solid polyethylene and high density polyethylene products, together with compositions and methods for producing these products, are provided. Polymer coatings comprising vinyl, urethane, and/or epoxy are covalently grafted to polyethylene substrates. The grafted coatings optionally colorants, flame retardants, and the like, that impart desired improved properties to polyethylene substrates. Grafted substrates include, for example, boards, sheets, tubing, pipes and the like. The treated products are more fire resistant than untreated polyethylene and unlike untreated polyethylene, are also capable of retaining post-manufacturing paint, markings, or adhesives, as desired.

Coating composition for high density polyethylene tubing

A composition and method that provides a chemically grafted coating onto a substrate. The composition comprises an acrylate and a grafting initiator. The acrylate may be a waterborne urethane acrylate. The composition may also comprise resistance agents, adhesion agents, UV curing photoinitiators, defoaming agent, and/or deglossing agents. The substrate may be any wood or plastic, but works well with heat shrinkable polyolefin tubing. The composition may also be quick curing such that the coating from the composition may be cured under a D bulb and an H bulb at a rate of 100-160 feet/minute. The coating on the substrate resists delamination and wear. The coating may have indicia printed on the coating, the indicia being composed from ink or other printable materials.

Chemical grafting onto a substrate and coating composition

This invention relates to the coating of steel parts with organic polymeric materials for resistance to corrosion, abrasion, impact, salt solutions of high and low pH (both in liquid as well as vapor state) and corrosive atmospheric gases under the environment of high relative humidity and ambient conditions of temperature and pressure. To obtain secure and permanent adhesion of the coating on the steel article a polymeric coating is formulated so as to achieve chemical grafting to the steel face. This involves the use of monomers, prepolymers, catalyst and a graft initiator system. The monomers are preferably polyfunctional and when applied onto a metallic substrate, react via graft polymerization with the metal to form a polymerized layer coated onto the surface of the steel substrate. The monomers and prepolymers are so selected that when polymerized onto steel the coating has substantially zero moisture vapor-gas transmission rate and consequently acts as a barrier to moisture, oxygen and other gases from coming in contact with the surface of the steel substrate thereby improving the protective potential of the coating. Fillers may be included in the coating material to enhance physical or wear characteristics. Other components that can be added are slip agents, wetting agents, thixotropic promoters and adhesion promoters. This coating process is particularly advantageous for use with steel parts used in the manufacture of cranes

Polymer grafted cotton

Polymer for printed cotton

A coating formulation for application to surfaces associated with combustion, such as fuel injectors, and surfaces subjected to elevated temperatures, such as fuel supply components, to prevent the deposition at high temperatures of carbon or graphite on such surfaces, such as stainless steel and alloyed steel compositions. The coating formulation forms a thin layer of polymer coating on the surface by chemical grafting involving the use of a graft initiator to create active bonding sites, on the metal surface, for the silicone-based prepolymer to undergo polymerization on the metal surface. The bonding and polymerization are completed in a single application process without using complex equipment. The coating and process helps surfaces associated with combustion and surfaces subjected to elevated temperature reduce carbon or coke formation at temperatures up to 700&deg; F. and thereby improves the durability and performance of those surfaces.
