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.

Provided is a vehicle interior material comprising coating layers formed on both surfaces of a veneer layer; a back layer on the coating layer of one surface of the veneer layer; and a front layer on the coating layer of the other surface of the veneer layer. Provided is a method of manufacturing a vehicle interior material comprising steps of: providing a veneer layer; forming coating layers on both surfaces of the veneer layer by applying and drying water-dispersible polyurethane dispersion or water-dispersible acrylic polyurethane dispersion on the both surfaces; pre-forming a real wood film layer prepared by forming the coating layers on the both surfaces of the veneer layer; forming a back layer on the coating layer of one surface of the veneer layer by primary insert molding; and forming a front layer on the coating layer of the other surface of the veneer layer by secondary insert molding.

An essentially 100% solids, single-component, UV curable, low-viscosity, penetrating sealant composition for wood substrates and other porous substrates is prepared from an acrylate-methacrylate mixture, a functionalized resin, an unsaturated fatty acid triglyceride oil, and a photoinitiator. The sealant composition may further contain a metal catalyst, an amine synergist, fillers, pigments, dyes, flow and leveling additives, air release chemicals, UV absorbers, hindered amine light stabilizers, fungicides, insect repellents, and/or mold inhibitors. The sealant composition exhibits fast cure times along with resistance to degradation.

A method of manufacturing a core for a composite material sandwich panel, the method comprising the steps of: providing a sheet of balsawood with opposite major surfaces, with vessels and axial parenchyma cells of the balsawood extending between the opposite major surfaces in a thickness direction of the sheet; coating a layer of a curable resin composition onto respective opposite major surfaces of the sheet of balsawood; and curing the curable resin composition, wherein the resin composition is applied and cured so that the coating layer of cured resin composition unevenly fills or only partly fills outermost ends of at least some of the vessels in the balsawood and thereby provides, at least in the vicinity of at least some of the vessels, a non-planar outer surface of the coating layer of the cured resin composition over the opposite major surfaces.
