Some variations provide a method of forming a transparent icephobic coating, comprising: obtaining a hardenable precursor comprising a first component and a plurality of inclusions containing a second component, wherein one of the first component or the second component is a low-surface-energy polymer, and the other is a hygroscopic material; applying mechanical shear and/or sonication to the hardenable precursor; disposing the hardenable precursor onto a substrate; and curing the hardenable precursor to form a transparent icephobic coating. The coating contains a hardened continuous matrix containing regions of the first component separated from regions of the second component on an average length scale of phase inhomogeneity from 10 nanometers to 10 microns, such as less than 1 micron, or less than 100 nanometers. The transparent icephobic coating may be characterized by a light transmittance of at least 50% at wavelengths from 400 nm to 800 nm, through a 100-micron coating.

Disclosed is a method for treating a grained material. A nonlimiting example of the method includes the operations of providing a workpiece having grains, exasperating a surface of the workpiece to open the grains, applying at least one coat of a base paint to the exasperated surface, applying at least one layer of clear coat on the base paint, applying at least one of a glaze and a paint on the clear coat, and surface treating to reveal grains of the workpiece. Disclosed also are items of furniture and sheet materials treated by the aforementioned process.

A solvent borne coating composition comprising: from 15-40 wt. % of a polyester resin, from 5-15 wt. % of a guanamine formaldehyde resin having no polyester groups, from 22-72 wt. % solvents with a boiling point of 50-98° C. and a curing catalyst. The composition is advantageously used of the application of multiple coloured layers on a metal or metal alloy foil. After the application of the composition, the metal or metal alloy foil can be further processed.

A method of sealing surface imperfections on a sanded surface of a repair to a vehicle body is provided that includes an uncured layer of a formulation being applied to sanded cured body filler on the vehicle body. The formulation includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The uncured layer is exposed to actinic radiation to induce cure of the uncured layer to form a sealing coating. The resulting seal coating has able to seal surface imperfections. A surface imperfection sealing formulation is also provided that includes a polyester resin and a multifunctional crosslinking agent. A solvent is provided. A photoinitiator renders the formulation curable upon exposure to ultraviolet light exposure. A particulate filler is also present in an amount to result in a formulation with an uncured viscosity of between 2600 and 3000 centipoises.

A high-solid-content coating composition includes: (A) a hydroxy group-containing acrylic resin having an acid value in a range of 0 mgKOH/g to 30 mgKOH/g; (B) a hydroxy group-containing acrylic resin having an acid value in a range of 60 mgKOH/g to 120 mgKOH/g; and (C) a polyisocyanate compound, in which a solid content at the time of coating is 50 mass % or more.

Disclosed herein is a method for forming a multilayer coating film by sequentially coating an intermediate coating material composition, a base coating material composition and a clear coating material composition on a metal for a motor vehicle body or resin material and then thermally curing the compositions, where the clear coating material composition is obtained by mixing a main agent (A) and a curing agent (B).

One variation of a method for directly casting a thin layer onto a substrate includes: combining a prepolymer, a solvent, and a curing agent to define a viscous material; advancing a substrate from a roll across a surface continuously at a first speed; depositing the viscous material at a viscosity through a deposition head onto the substrate, the viscous material flowing laterally across the substrate to form a thin layer of substantially uniform thickness over the substrate over a period of time while the substrate advances along the surface; and, at a distance from the deposition head depositing the viscous material onto the substrate corresponding to a duration of time for the viscous material to flow laterally across the substrate, heating the viscous material to evaporate solvent and to induce reaction between the curing agent and the prepolymer to cure the viscous material to form a layer.

In some embodiments, a polymer film includes a base composition of poly(ethylene-vinyl acetate) and a surface composition comprising hydroxy groups. In some embodiments, a polymer film includes a base layer of a first composition of poly(ethylene-vinyl acetate), a surface layer at a surface of the base layer, and a coating layer of a second composition of a copolymer of glycerol and sebacic acid. The surface layer includes surface hydroxy groups converted from acetate groups of the poly(ethylene-vinyl acetate). The second composition is attached to the surface layer by ester bonds between carboxyl groups of the copolymer and the hydroxy groups. A single-use bioreactor bag includes a polymer film including a base composition of poly(ethylene-vinyl acetate) and a surface composition comprising hydroxy groups. A method of modifying a poly(ethylene-vinyl acetate) film includes converting acetate groups at a first surface of the poly(ethylene-vinyl acetate) film to hydroxy groups.

A sanitary article, which has a support body and an outer coating which is applied to the support body at least in certain portions and forms the outer side of the sanitary article, the support body being of a first composite material of a filled polymeric binder matrix containing at least one filler in the form of hollow glass beads and the outer coating being of a second composite material of a polymeric binder matrix, which is filled with at least one filler and does not contain any hollow glass beads.

A liquid polymeric coating composition that upon application to a substrate, such as a coil substrate, preferably does not exhibit the edge build and edge blistering that commonly occurs with conventional liquid polymeric coating compositions. In some embodiments, the liquid polymeric coating composition is modified by tailoring the surface tension, the openness of the coating composition as indicated by the modulus of elasticity, or a combination thereof to reduce edge build and edge blistering. The modified liquid polymeric composition may be applied to a surface of the substrate and cured to form a film coating that reduces or alleviates commonly encountered edge defects in conventional liquid polymeric coating compositions, such as edge build and edge blistering, which may avoid the need for edge trimming of the coated substrate. The coated coil substrate is well suited for forming food or beverage containers or portions thereof.
