Containers and other articles comprising the polymer and methods of making such containers and other articles are also provided. The invention further provides compositions including the polymer (e.g., powder coatings), which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.

System and method for inside of can curing

An improved inside of can curing technology is provided. One implementation uses narrowband, semiconductor produced infrared energy which is focused into the inside of the can to affect a very high-speed curing result and will directly impact the coating covering the inside walls of the can to rapidly cure the coating. De-tempering and annealing of the aluminum can body does not have time to occur, thus leaving a stronger can with the same amount of aluminum or a can of the same strength but with less aluminum. It is also possible to eliminate the natural gas fueled oven that is the current standard and replace it with a completely hydrocarbon-free curing alternative that has superior performance. This high powered radiant, narrowband energy will be digitally controlled to introduce only the needed heat and to not overheat the can.

Spray gun alignment for precision application of container coatings

A spray gun alignment system precisely aligns a spray gun of a container spray machine for precision application of container coatings. The spray gun alignment system generates a spray gun alignment jig including a container holder adapter and a spray gun adapter. The container holder adapter is inserted into a container holder of the spray machine, and the spray gun adapter is fastened to the spray gun. The spray gun alignment jig is configured to position the spray gun in proper alignment with respect to the container holder.

CROSSLINKED COATING COMPOSITIONS FOR PACKAGING ARTICLES SUCH AS FOOD AND BEVERAGE CONTAINERS

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.

Corrosion laminate system

The corrosion laminate system (CLS) comprises cleaning the produced water (PW) storage tank through debris removal, wet blasting the tank, and drying the tank. The nozzle is inserted and sealed, leaving only the fiberglass portion of the nozzle in contact with the interior of the PW storage tank. The product for sealing the PW storage tank is then applied to the entire interior surface of the tank, the product is cured, and the PW storage tank can be used for storage.

COATING COMPOSITION FOR BEVERAGE CONTAINERS

E-VAPING DEVICE CARTRIDGE WITH SUPERABSORBENT POLYMER
20170367403 · 2017-12-28 · ·

A cartridge for an e-vaping device includes a reservoir configured to hold pre-vapor formulation, a vaporizer assembly configured to draw at least some of the pre-vapor formulation from the reservoir and vaporize the drawn pre-vapor formulation to form a vapor, and a superabsorbent polymer configured to absorb free water from pre-vapor formulation held in the reservoir. The superabsorbent polymer includes a cross-linked polyacrylate copolymer that is substantially inert to the pre-vapor formulation. The superabsorbent polymer may be included in a layer on one or more surfaces in the cartridge. The layer may include the superabsorbent polymer and a binder. The superabsorbent polymer may be included with the pre-vapor formulation in a formulation mixture. The superabsorbent polymer may be included in an interior of at least one element comprising the cartridge. The superabsorbent polymer may be included in a separate compartment in the reservoir.

Decorative Defect Re-Basecoating System for Cans and other Cylindrical Containers
20230182159 · 2023-06-15 ·

A quick, practical and economical method, machine and system for re-basecoating cans which have necks, flanges but also have basecoat and or decoration defects. The cans may pass by a corona /plasma treatment which removes lubricant. A main starwheel will carry the cans to a can body coating application device (such as a high durometer resilient roller), then to a can neck coating application device (similar but shaped for the neck/flange of the can). The main starwheel will carry the cans through an induction tunnel in which cans have an electrical current induced, thereby curing the cans before the cans are removed by an outfeed device and placed onto an outfeed conveyor. Hold down chucks hold the cans from the top (in addition to vacuum chucks holding the cans from the bottom) and cover the top of the cans so that the new coating material does not enter.

Method for making water-dispersible and water-dispersed polymers

Water-dispersible or water-dispersed polymers are made by reacting (i) an unsaturated monomer containing one or more cyclic carbonate groups, or (ii) an unsaturated or saturated oligomer or polymer containing a plurality of cyclic carbonate groups, with a tertiary amine in the presence of an acid, or with an acid in the presence of a tertiary amine, or in the presence of an acid and a tertiary amine, to provide a water-dispersible or water-dispersed monomer, oligomer or polymer. When step a) provides a monomer or oligomer, the monomer or oligomer is reacted with one or more monomers in the presence of an initiator to provide a water-dispersible or water-dispersed polymer. When step a) provides a polymer, the polymer is optionally used to support emulsion polymerization of one or more unsaturated monomers in the presence of an initiator to provide a water-dispersible or water-dispersed further polymer.
