A process for applying a coating material onto a substrate as a non-uniform discontinuous pattern of coating material, the method including the present disclosure describes a method of applying a coating material onto a substrate, including providing a first distribution manifold having a cavity and a multiplicity of first dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction; dispensing a first coating material from the dispensing outlets while maintaining the relative motion and translating the multiplicity of dispensing outlets in a second direction non-parallel to the first direction, and varying a rate of dispensing of the first coating material in a predetermined fashion to form a discontinuous pattern of the first coating material on a major surface of the substrate. Useful non-uniformly patterned coated articles can be prepared using the process.

A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.

According to certain embodiments, a method of producing a pattern on a substrate comprises securing a flexible polymeric substrate, printing a layer of ink as a negative pattern on the substrate, and placing the flexible polymeric substrate in a vacuum chamber. The method further includes uniformly applying, while the flexible polymeric is under a vacuum in the vacuum chamber, a layer of material over both the layer of ink and the substrate via physical vapor deposition and then removing the flexible polymeric substrate from the vacuum chamber. The method further includes removing the ink and material applied over the ink by immersing the flexible polymeric substrate in a solvent such that it results in a desired pattern of the material on the flexible polymeric substrate.

A slot die shim for use with a slot die, the slot die shim including a first channel configured to receive a first coating, a second channel configured to receive a second coating, and a third channel configured to receive a third coating. The slot die shim simultaneously dispenses the first coating through the first channel, the second coating through the second channel, and the third coating through the third channel onto a substrate. The coatings can be applied at different flow rates and include different test reagents. A vacuum force is applied to the first, second, and third coatings to control a width and a thickness of each of the coatings and a gap or distance between the coatings. The first, second, and third coatings are placed near one another or directly in contact with one another to minimize the area required for the coatings.

A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes a latex copolymer and a metal drier or crosslinking agent. The latex copolymer is a reaction product of monomers that include (a) one or more styrene-mimicking monomers containing one or more cyclic groups and one or more ethylenically-unsaturated groups, at least a portion of such styrene-mimicking monomers being polycyclic monomers containing ring unsaturation, and (b) one or more other ethylenically-unsaturated monomers. Preferably, the coating composition is substantially free of each of BPA, PVC, other halogenated monomers, and optionally styrene. The method may also include curing the sprayed coating composition, thereby providing the coating on the interior surface of the food or beverage container.

A dry electrode manufacturing process is employed for low cost battery through a dry mixing and formation process. A thermal activation renders the dry fabricated electrode comparable to conventional slurry casted electrodes. The dry electrode mixture results from a combination of a plurality of types of constituent particles, including at least an active charge material and a binder, and typically a conductive material such as carbon. The process heats the deposited mixture to a moderate temperature for activating the binder for adhering the mixture to the substrate, and compresses the deposited mixture to a thickness for achieving an electrical sufficiency of the compressed, deposited mixture as a charge material in a lithium-ion battery. In order to increase the bonding between the current collector and charge materials, an adhesive interlayer is applied through dry printing.
