Abstract: Coating compositions are disclosed which use a polyoxetane polymer having CH.sub.2 --O---CH.sub.2 --R.sub.f side chains where R.sub.f is a highly fluorinated alkyl or polyether. The coating compositions use polyisocyanates to create isocyanate terminated polymers from the poly(oxetanes) and from various polyols from alkylene oxides or polyester polyols. These can be reacted together to form block copolymer structures or can be linked together when the coating is crosslinked. A preferred method is to use blocked isocyanate groups. Another preferred embodiment is to use the composition as a abrasion resistant coating for glass run channels.

The adhesive is formulated from a latex which includes at least one conjugated diene and a macromonomer containing at least two ethylene oxide repeat units.

Abstract: A sill cover article for automobiles and other vehicles which has a first, relatively rigid sill cover portion and a second, relatively flexible lower door sealing portion that is manufactured as a single component and can be attached to a vehicle in a single mounting operation. The sill cover article is preferably manufactured of two materials of different durometer which are coextruded to form a single component. The sill cover article or a portion thereof may be provided with various coatings and/or additives to provide the article with desired properties. For example, the lower door sealing portion may be provided with an ice-release agent to prevent ice from forming on a surface thereof. The sill cover article of the present invention provides a reduction in assembly time, inventory requirements and overall manufacturing costs of a vehicle.

One of the work stations is an assembly station engaged with the rotatable work table for receiving work pieces from their individual work piece supports. The assembly station further includes a removing subassembly for removing the work pieces from the work piece supports for further assembly.

Abstract: A moisture-permeable acoustic lamina which is usable as a wall covering has a foraminous woven fabric layer adhered to a fabric backing by a discontinuous thermoplastic polymer layer. The woven fabric preferably has an embossed undulate outer surface to enhance the acoustic properties of the lamina and to impart an aesthetic textural appearance. The individual yarns of the woven fabric are preferably substantially uniformly coated with a polyvinyl chloride plastisol to impart stain and wear-resistance, inhibit the growth of molds, fungi, bacteria and the like, and to enhance the appearance of the exposed face of the lamina. The moisture-permeable lamina structure allows wall covering paste, used to adhere the lamina to a wall, to dry at an acceptable rate, yet does not allow paste to bleed through the foraminous woven fabric layer.

Abstract: A latex useful as a binder for paper, nonwovens, and textiles is prepared by copolymerizing in aqueous emulsion using a redox initiator at 5.degree. C. a mixture of 35 to 60% weight of a conjugated diene monomer and from about 30 to 65% by weight of a vinyl aryl monomer. Additional improvements can be obtained by incorporating in the mixture a small percentage by weight of copolymerizable monomers such as acrylic acid, methacrylic acid, itaconic acid and/or a functional type monomer having an activatable methyl, ethyl, propyl or butyl ester group and a vinyl group.

Abstract: A weatherstrip seal comprises a carrier structure without embedded reinforcement that has an attached weather-sealing structure extending therefrom. The carrier structure has two spaced-apart legs connected by a base, the interior walls of the legs forming a channel therebetween. Finger-like members extending from the walls are adapted to frictionally engage and hold a mounting flange inserted into the channel. The legs decrease in thickness as they proceed outwardly from the base and their walls converge inwardly toward each other, minimizing the material required for fabrication of the carrier and enhancing its ability to withstand forces acting to dislodge the mounting flange from the channel, especially at corners thereof.

Abstract: A latex binder composition which is the reaction product of a conjugated diene monomer and a vinyl-substituted aromatic monomer along with minor amounts of other comonomers including acrylamide or a derivative thereof, methacrylic acid, N-methylolacrylamide, and optional unsaturated carboxylic acids, has an average particle size of less than 1,500 .ANG.. The latex binder which has good stability can be used on nonwoven cellulosic based substrates to impart high wet tensile strength thereto.

The weatherstrip includes a foot of pliable uncured elastomeric material and a seal member of cured elastomeric material formed integral with said uncured foot. The seal member has a retention member which forces the foot within imperfections and variations in the retention flange to provide a weather resistant seal with the retention flange.

The apparatus 10 includes a base frame 11 supporting a driver 12 and a power supply, and a support member 16 for engagement with the molded part M. The driver 12 is engaged with and driven by the power supply M. The support member 16 has a clamping station for receiving and clamping the mold section C engaged with the molded part M. The clamping station 20 also has an open position for receiving the mold section C engaged with the molded part, and a closed position in which the mold section and molded part are clamped within the clamping station. The clamping station 20 further includes a heater 44, to assist with partial heating of the molded part M and mold section C prior to removal of the molded part.

Abstract: The present invention relates to a method of splicing a hollow gasket such that the final welded joint remains highly flexible and does not impair the fluid flow between the two spliced sections. The two gasket sections having identical multiple-chambered cross-sections are held in a splice mold by precision tooling and air drawn through small holes in the splice mold by a vacuum pump. Heat is applied to each end of the gasket sections and the ends are brought into contact with one another. As the ends cool, a welded joint is formed. The integrity of each individual chamber is maintained so that, when spliced, the two gaskets sections become one, with the chambers forming continuous channels. The continuous channels create a higher insulating quality than if the channels were blocked at the welded joints. Further, corners spliced in this manner remain as flexible as the adjoining gasket sections.

Abstract: A two-component urethane adhesive is disclosed which requires no primer or pretreatment of the substrate. The adhesive in cured form has superior paint adhesion and can withstand high temperature bake cycles without substantial losses in adhesion to the substrate. The adhesive differs from prior adhesives in that essentially all of the high molecular weight polyols in the prepolymer component are the reaction product grafting reactions of acrylonitrile onto polypropylene polyols.

Abstract: An anti-fracture, water-resistant, masonry-bondable membrane comprises a lamina having a central layer generally containing at least one ply of a flexible material, e.g., an organic polymer such as polyvinyl chloride, generally in the form of a sheet, and a nonwoven fiber layer physically bonded to each side thereof. The formation of the lamina is generally accomplished by laminating a single, nonwoven layer to a layer or sheet of a flexible material in the presence of heat and pressure to produce a construction wherein the nonwoven fibers are partially embedded in the flexible material. Subsequently, two such constructions are bonded together under heat and pressure to produce essentially a four-ply lamina wherein the layers of flexible material such as a polymer are fused to one another.

Abstract: A reinforced tape strip for securing a membrane roof to a roof deck or a parapet wall of a roof deck. The reinforced tape strip includes a layer of a single ply reinforcement material, at least one adhesive layer of a uniform thickness bonded to the single ply reinforcement material, and a protective layer covering the adhesive layer.

Abstract: Low air permeable, pressurized articles such as play balls, e.g., a tennis ball, have a thin barrier layer formed on the vulcanized rubber core. The barrier layer is chemically bonded to the internal and/or external surface of the core, e.g., by the reaction of a Lewis acid, e.g., sulfur trioxide, with the core rubber. The thin barrier layer permits the tennis ball to be flexible and have good rebound life and yet extends the play life thereof before ball rebound or softness changes to undesired levels.
