An object is to provide a resin composition having excellent performance as a binder such as adhesiveness and, at the same time, retaining solution properties favorably even after a solution is stored for a long period of time. A modified polyolefin resin composition includes a modified polyolefin resin (C), in which the modified polyolefin resin (C) is a resin made by modifying a polymer (A) that is a polymer (a) of a polyolefin resin or a chlorinated polyolefin resin and an α,β-unsaturated carboxylic acid derivative having a structure derived from at least one carboxy group or a chlorinated product (b) thereof with a modification component including an alcohol (B); and a residual ratio of the structure derived from at least one carboxy group in the modified polyolefin resin (C) is 50% or more and 80% or less.

The present application relates to a two-component aqueous sealing primer for wood, comprising: Component A: a film-forming resin composition comprising at least one aqueous emulsion of cationic resin and optionally at least one additional additive; and Component B: a curing agent composition comprising at least one polyisocyanate.

The formed sealing coating can substantially seal the tannin, grease, and other substances in the wood, and has good sandability.

The present disclosure relates to a primer coating material composition, obtainable by combining at least two components (A) and (B) of a coating material system, which are different from one another and present separately from one another, with component (B) being nonaqueous and including at least one polyisocyanate having more than two free isocyanate groups, at least one organic solvent, and, further, at least one Si-containing compound which contains at least one hydrolyzable radical and at least one non-hydrolyzable organic radical, for at least partial application to at least one optionally pretreated surface of a plastics substrate, to a method for producing a corresponding coating on such a substrate, and to a method for at least partially coating at least one surface of a plastics substrate with a multicoat paint system.

An aerosol primer composition includes a film forming component and a propellant component. The film forming component includes (by weight of the composition): (a) at least one of a polyurethane and alkyd from about 10% to about 20%, (b) cellulosic particles from about 2% to about 5%, and (c) an aqueous solvent system from about 20% to about 40%. The propellant component includes dimethyl ether. The aerosol primer composition can be stored within a spray assembly and the propellant component can be configured to pressurize the film forming component for dispensing from the spray assembly as an aerosol. The aerosol primer composition can be used to prime a substrate to be painted or stained.

A method of treating a surface is provided. The method includes disposing a condensation reduction composition on the surface, thereby treating the surface to reduce formation of condensate and/or an amount of condensate thereon. The condensation reduction composition comprises a surface-active agent comprising an alkyl polyglycoside. The condensation reduction composition may further comprise a preservative, a pH control agent, and/or water. A treated surface prepared in accordance with the method is also provided. The method and treated surface prepared therewith are useful in reducing condensate and/or formation of condensate on surfaces, e.g. by reducing the number of condensate drops falling from the surface, increasing the rate of condensate evaporation on the surface, and/or increasing the rate of water absorption into or through the surface, e.g. upon or during exposure of the treated surface to a condensation condition.

Photocurable adhesion-promoting compositions containing organic titanates and/or organic zirconates and partially reacted alkoxysilanes and the use of the photocurable adhesion-promoting compositions to provide adhesion between metal substrates and an overlying radiation-cured sealant are disclosed.

A composite medium for collecting mineral particles in an aqueous slurry has a polymer substrate deposited or penetrated with an inorganic material and further coated with a hydrophobic material. The hydrophobic material can be a hydrophobic silane or a hydrophobic polymer such as polysiloxane. Alternatively, the inorganic material deposited substrate is first reacted with a reactive silane and then coated with a hydrophobic polymer. The polymer substrate can be in the form of a spherical bead, a small cube, a filter or a conveyor.

The present disclosure relates to an aqueous epoxy resin based shop primer comprising: a) a film-forming resin composition comprising: i) an epoxy resin component; and ii) an aqueous carrier; b) an aqueous curing system comprising an epoxy reactive curing agent; wherein the epoxy resin component comprises: an epoxy resin matrix and a rubber modified epoxy resin; and wherein the shop primer is substantially free of zinc. The present disclosure also relates to an article comprising a metal substrate having at least one major surface; and a shop primer layer formed by the above mentioned aqueous epoxy resin-based shop primer directly applied to the major surface.

A laminate that includes a substrate made of a polyolefin-based resin and is excellent in adhesion between the substrate and a metal plating layer is provided in a simple manner without roughening the surface of the substrate. In addition, a molded article, a printed wring board, and an electromagnetic wave shield using the laminate using the same are provided. Used is a laminate configured such that on a substrate (A) made of a polyolefin-based resin (a), a primer layer (B) containing a polyolefin-based resin (b) that is organic solvent soluble or water dispersible, a metal particle layer (C), and a metal plating layer (D) are sequentially laminated.

The present application relates to an optical film, a method for preparing an optical film, and a method for manufacturing an organic light emitting electronic device.
