Overvarnished aluminum cans which are not usable because of label graphic errors or other reasons are conditioned for reuse by first treating the existing overvarnish to accept an opaque new layer of overvarnish. The opening of the can is engaged with a plug having a pin communicating with a pressurized gas supporting the can on a wheel to supply gas pressure according to the rotational position of the pin. The overvarnished can is pressurized to allow printing an opaque new layer of overvarnish on to the can over the existing overvarnish. The treated can is visually inspected and the internal coating resprayed, and the opaque overvarnish and the internal coating are cured in a final curing oven, the can being then ready for printing of new graphics or sold as a brite, silver or blank can where other graphics can be applied.

A vessel has a lumen defined at least in part by a wall. The wall has an interior surface facing the lumen, an outer surface, and a plasma-enhanced chemical vapor deposition (PECVD) coating set supported by the wall. The PECVD coating set comprises a water barrier coating or layer having a water contact angle from 80 to 180 degrees, applied using a precursor comprising at least one of a saturated or unsaturated fluorocarbon precursor having from 1 to 6 carbon atoms and a saturated or unsaturated hydrocarbon having from 1 to 6 carbon atoms. Optionally, the coating set includes an SiOx gas barrier coating or layer from 2 to 1000 nm thick, in which x is from 1.5 to 2.9 as measured by x-ray photoelectron spectroscopy (XPS), and optionally other related coatings.

The present disclosure provides a curable resin composition including a thermoset resin, a toughener component containing a multistage polymer and a thermoplastic toughener and a phenylindane diamine hardener. The curable resin composition may be used in various applications, such as a coating for industrial, automotive and electronic applications, and especially those subjected to high temperature service conditions.

A device for coating a cylinder includes a coating head capable of being inserted into the cylinder, a plurality of coating guns which are provided on the coating head and are configured to discharge a coating material in a direction intersecting a longitudinal direction of the coating head, and a rotating cover which, when the coating material is discharged from one of a first coating gun and a second coating gun among the plurality of coating guns, is configured to cover the other of the first coating gun and the second coating gun, in which the plurality of coating guns are connected to coating material supply devices of different systems, respectively.

The disclosure relates to a substrate coating apparatus that comprises a source of a washcoat; a washcoat showerhead for discharging the washcoat towards an upper surface of a substrate; a conduit fluidly connecting the source of the washcoat to the washcoat showerhead for supplying washcoat to the washcoat showerhead; a headset for engaging the substrate to locate the upper surface of the substrate below the washcoat showerhead; and a vacuum generator for drawing the washcoat discharged from the washcoat showerhead through the substrate. The headset comprises a partition comprising a plurality of holes, the partition being located in between the washcoat showerhead and the upper surface of the substrate when the substrate is engaged in the headset so as to maintain a first gap between a lower face of the partition and the upper surface of the substrate.

The device is for curing a coating substance inside a pipe. The device has a flexible shaft inside a duct, an air inlet channel within the duct, a body configured to be attached to the duct, a heat sink in connection with the body and defining a plurality of cooling channels which are in fluid connection with the air inlet channel. The device further has a plurality of light emitting devices configured to be cooled by the heat sink. The device further has an air outlet channel in fluid connection with the cooling channels of the heat sink. The air outlet channel exits the body from the same side of the body as the air inlet channel enters the body.

A method of coating a high-pressure fluid vessel comprises filling a high-pressure fluid vessel with a coating solution, draining the coating solution, and drying a remainder of the coating solution in the high-pressure fluid vessel. The coating solution may include a thermoplastic elastomer that is hard with a low glass transition temperature and a high melting temperature. Drying the remainder of the coating solution may form a food grade coating within the high-pressure fluid vessel.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A method for treating a substrate with a volatile liquid, crop-preservative formulation includes transporting a predetermined quantity of the formulation from a reservoir to an injection device and applying the predetermined quantity to the substrate. The substrate may thereafter be in proximity to a crop to be treated by the vapor from the formulation. The substrate is most conveniently a portion of a container in which the crop is stored or shipped.
