Abstract: A coated paper stock having high moisture vapor barrier characteristics and ingredient compatible with recycling and repulping is disclosed comprising a substrate coated on at least one surface with a subcoat. The subcoat comprises a hydrolyzed amphoteric vegetable protein at at least 11 weight percent based on weight of the subcoat. A top coat is coated over said subcoat. The top coat consists essentially of a water-based dispersion of a film forming vinyl addition polymer, conjugated diene polymer or copolymer of either polymer, such as acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, styrene acrylate copolymers, styrene butadiene copolymers, polyvinylidene chloride and polyvinylidene chloride copolymers. The top coat is substantially free of mineral pigments that interfere with the moisture vapor barrier characteristics. The vegetable protein is preferably a hydrolyzed amphoteric soybean protein with an average molecular weight less than 400,000 Daltons.

Abstract: Fluoropolymer particles are subjected to high energy treatment so as to change the chemical functionality of the particle surfaces and thereby change the surface characteristics of the particles. These characteristics improve the usefulness of these particles and can make them highly dispersible, even in water. The surface treated fluoropolymer particles are subject to a chemical crosslinking process, or alternatively, are subject to a high energy treatment process, and may optionally be pretreated with a macromolecular chemical species prior to the foregoing processes. The high energy treatment can be used to both surface treat the fluoropolymer particles and in some embodiments, may also cause chain scission of the fluoropolymers to thereby reduce the molecular weight of the fluoropolymer particles. The surface treated fluoropolymer particles can be used to form fluoropolymer coatings on various substrates.

Abstract: A method of affixing a gasket to a transparent substrate utilizing a fixture having a channel formed therein, into which the gasket is inserted and held in place by, for example, a vacuum. Alternatively, a removable form may be inserted into the channel, and the elastomeric member/gasket is inserted into the removable form. A suitable substrate is precisely positioned on the fixture in a predetermined position relative to the elastomeric member. An adhesion promoting primer may be applied to the substrate, and an adhesive may be applied to the gasket, or to the substrate. The elastomeric member is then bonded to the transparent substrate. Finally, the completed assembly is removed from the fixture.
