Abstract: 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.

Abstract: A solution for forming a graft substrate containing a graft initiator, a catalyst for activating or regenerating the graft initiator, a first component of water dispersable polymer and a second component of a monomer, each of which includes a functional group for reaction with an activated site on the substrate for grafting thereto and water. A method for grafting at least one of the components to a fiber, yarn or fabric substrate is also disclosed wherein increased flame retarding and yarn integrity is achieved while simultaneously allowing control of fabric porosity. This method does not significantly reduce fabric pliability as compared to uncoated fabric. Furthermore, the graft component may be selectively applied polymer to produce a preferred porosity range or a cutting pattern for the fabric substrate. A fabric, a portion of which includes a graft component or components thereon, forms another embodiment of the invention.

Abstract: Coating solution for papermaking fabrics that includes as its primary components polytetrafluoroethylane, urethane copolymer and polyacrylamide. The coating composition is prepared in a solution, coated on the fabric and cured. A fabric thus treated has permanent anti sticking properties against pressure sensitive adhesives, pitch from wood pulp, ink deposition and the like.

Abstract: A papermaking fabric having permanent resistance to adhesion of contaminants, and a method to make such a fabric by treatment of a papermakers fabric with a solution having as its primary components tetrafluoroethylene, urethane copolymer and polyacrylamide. The treatment, prepared in a solution, is coated on the fabric and cured to impart permanent anti-sticking properties to the fabric.

Abstract: A method of grafting a conductive, tenacious, and protective coating on a metallic substrate. The metallic substrate, such as steel, aluminum, iron, platinum, silver, nickel, gold, cobalt, copper, copper alloys, or combinations thereof, is contacted with a composition having: (i) one or more polymerizable monomers having at least two functionalities; (ii) one or more graft initiators containing nickel ion in an amount effective to initiate the graft polymerization of the monomers; and (iii) a reducing agent capable of reducing nickel ion to nickel metal. The composition and substrate are heated for a time and at a temperature effective to graft polymerize the monomers and nickel metal onto the substrate and form a conductive, tenacious, and protective coating bonded to the substrate. The coating can also contain elemental phosphorous. Preferably, the coated substrate has a surface resistivity of less than 0.1 ohm per square.

Abstract: A bowling ball, rather than being engraved with a decoration, is printed with the decoration, relying on graft polymerization chemistry by which the printing fluid, offset to the ball in decoration form, is effectively bonded to the ball which may be rubber or other polymer capable of participating in graft polymerization.

Abstract: Dispersions of titanium dioxide pigments with improved long-term resistance to pigment settling and precipitation are disclosed. The pigment dispersions are formed by chemically grafting vinyl and/or acrylic polymers to nitrocellulose in dispersions of nitrocellulose and titanium dioxide pigments. Nitrocellulose forms a loose association with titanium dioxide in dispersion. The chemical grafting improves the precipitation and settling resistance of nitrocellulose, and thus the precipitation and settling resistance of the associated titanium dioxide.
