A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

The use of redsipersible polymer powders containing no organic emulsifier for a binder in the production of carpeting is surprisingly superior to use of the same polymers in the form of an aqueous dispersion. Tuft removal force in particular, is improved. The compositions contain no thickener, or a reduced level of thickener.

The invention comprises a method of making synthetic turf. The method comprises applying an ethylene-vinyl acetate copolymer adhesive to a first primary surface of a tufted primary backing to form a coating thereon and wherein the primary backing is tufted with a plurality of synthetic filaments to form a face pile extending outwardly from a second primary surface of the synthetic turf opposite the first primary surface and heating the ethylene-vinyl acetate copolymer adhesive to a temperature above its melting point so that the ethylene-vinyl acetate copolymer adhesive melts and at least partially flows into the primary backing. The method also comprises heating a linear low-density polyethylene film to a temperature below the softening point of the film and pressing the heated linear low-density polyethylene film into contact with the polymer coated first primary surface of the tufted primary backing. The method further comprises allowing the ethylene-vinyl acetate copolymer adhesive and the linear low-density polyethylene film to cool, whereby the linear low-density polyethylene film is adhered to the tufted primary backing.

A ballistic fiber composition may include a fabric that may be comprised of polyamide fibers, an adhesive polymer coating the fabric, and a carbonaceous material and a ceramic filler embedded in the adhesive polymer coating. A method of producing a ballistic protective article may include mixing a carbonaceous material and a ceramic filler into an adhesive to create a mixture, and then coating a polyamide fabric with the mixture. A ballistic protective article may include an aromatic polyamide fabric that is coated with an elastomeric adhesive polymer coating, with calcium carbonate and a carbonaceous material embedded in the elastomeric adhesive polymer coating. The carbonaceous material may include at least one material selected from graphene, carbon nanofiber, and carbon nanotubes.

A method for forming an antimicrobial coating on a substrate is provided. The method comprises dissipating and entrapping (embedding) sulfonated copolymer particles in void spaces or interstices of fibers of a fabric forming an outer layer of a substrate. The sulfonated copolymer is selected from the group of perfluorosulfonic acid polymers such as sulfonated tetrafluoroethylene, polystyrene sulfonates, sulfonated block copolymers, polysulfones such as polyether sulfone, polyketones such as polyether ketone, sulfonated poly(arylene ether), and mixtures thereof. The fibers comprise a thermoplastic polymer having a melting point of less than 120° C., or 45-110° C., or 45-80° C. The sulfonated copolymer forms an antimicrobial coating layer for killing at least 90% microbes in the air within 30 minutes of contact with the coating.
