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.

The present invention relates to a polymeric coating composition for application onto glass substrates for anti-reflective properties. The coating is provided via chemical grafting that involves the use of monomers and/or prepolymers, catalyst, and graft initiator and when applied onto the surface of the glass substrate forms a polymeric film chemically bonded to the glass with excellent adhesion. This coating can reduce the reflectance of the coated glass surface to as close to zero as possible, thus maximizing transmittance and providing resistance to abrasion, water/chemical attack, and UV degradation.

Crosslinkable aqueous-based coating compositions are described which are covalently bonded to a wooden surface to which they are applied. The compositions contain a crosslinkable polymer, a mono and/or polyethylenically unsaturated monomer which can be graft polymerized onto cellulose molecules present in said wooden surface, a water soluble peroxy free radical polymerization catalyst, a source of cations capable of creating free radical sites in said cellulose molecules and, optionally, a crosslinking agent for said crosslinkable polymer. The coating may be air dried under ambient conditions to provide a crosslinked coating which is chemically bonded to the underlying wooden surface.

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

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.
