A continuous method of manufacturing adhesives is provided. The method includes obtaining an actinic radiation-polymerizable adhesive precursor composition disposed on a major surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes moving the actinic radiation-transparent substrate and irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. Optionally, the method also includes irradiating a third portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate prior to moving the substrate. The first irradiation dosage and the third irradiation dosage are often not the same, thereby forming an integral adhesive having a variable thickness in an axis normal to the actinic radiation-transparent substrate.

A liquid discharge apparatus includes a liquid discharge unit and a contact detection unit. The liquid discharge unit has a liquid discharge port from which a liquid is discharged toward an object. The liquid discharge unit is movable along at least one of a first axis and a second axis intersecting the first axis and movable along a third axis intersecting the first axis and the second axis. The third axis is parallel to a direction in which the liquid is discharged from the liquid discharge port toward the object. The contact detection unit detects contact of the liquid discharge unit with the object. The contact detection unit is detachably attached to the liquid discharge unit.

Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.

An apparatus and method for coating an electrode slurry are disclosed herein. In some embodiments, the apparatus includes a coater configured to coat an electrode slurry on a metal foil, a measuring unit is configured to measure a remaining oil level on a surface of the metal foil before the coater coating the electrode slurry, and a controller configured to control the coater to coat the electrode slurry based on a measurement value of the remaining oil level of the surface of the metal foil.

A painting method and a painting apparatus for a band material that prevent a printing defect during a long-time operation by preventing agglomeration and adhesion of a thixotropic paint in a paint pan is disclosed. The liquid paint is discharged to the paint pan as a jet flow from a level lower than a liquid surface of a paint basin toward a bottom of the paint pan, thereby creating a bottom flow along the bottom of the paint pan and an upward vortex from the bottom along a side wall of the paint pan. The liquid paint overflows in an amount corresponding to a supplied amount to the paint pan from a front upper edge of the paint pan in a flowing direction of the bottom flow, thereby flowing the liquid paint continuously in the paint pan toward the front upper edge.

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 method and apparatus for coating an electrode is disclosed herein. In some embodiments, an apparatus for coating an electrode slurry includes a coating die configured to coat an electrode slurry on one surface of a current collector, a thickness measuring sensor spaced apart from the current collector by a predetermined interval and configured to measure a thickness of the coated electrode slurry in real time after coating by the coating die; and a controller which controls a coated amount of the electrode slurry in real time according to the measured thickness.

Beverage containers and methods of coating are provided. The beverage containers include a metal substrate that is at least partially coated with a coating prepared from a composition that includes a binder system, a cross linker, and a catalyst.

A coating apparatus includes: a container configured to accumulate a coating liquid; a rotatable coating bar arranged at an opening part so that the coating bar has a clearance between the coating bar and a downstream side end of an upstream side cover and a clearance between the coating bar and an upstream side end of a downstream side cover and a rotation axis direction of the coating bar is directed in a longitudinal direction of the container; a plurality of rotatable supports intermittently arranged along the rotation axis direction of the coating bar; and an in-liquid cover extending in the longitudinal direction of the container.

A method for manufacturing an aluminum alloy sheet may include melting aluminum alloy composition containing silicon (Si), iron (Fe), copper (Cu) and manganese (Mn) in weight % on the basis of remainder of aluminum (Al) to make cast alloy having a constant initial thickness; rolling the cast alloy to allow the initial thickness to be reduced, whereby the cast alloy is elongated to aluminum alloy sheet; and performing heat treatment on the aluminum alloy sheet.
