Abstract:
Coating adhesion on wooden members, such as wooden railroad crossties, is improved through use of three surface-treating techniques prior to application of the coating. The first technique involves forming grooves on the surface of the wooden article, the second technique involves exposing the wooden article to heat to reduce the moisture content of the surface of the wooden article, and the third technique involves creating incisions on the surface of the wooden article to further promote adhesion. The techniques may be advantageously used together to further enhance coating adhesion.
Abstract:
Exemplary pressurization and coating systems, methods, and apparatuses are described herein. In certain embodiments, pressurization systems, methods, and apparatuses are used in conjunction with coating systems, methods, and apparatuses to control pressure about a substrate after a coating material is applied to a surface of the substrate. An exemplary system includes a die tool configured to apply a coating material to a substrate passing through the die tool and a pressurization apparatus attached to the die tool and forming a pressurization chamber. The pressurization apparatus is configured to receive the substrate from the die tool and control pressure about the substrate in the pressurization chamber. In certain embodiments, the die tool forms a coating chamber and is configured to apply the coating material on at least one surface of the substrate in the coating chamber.
Abstract:
A tinted coating for a hard-surfaced floor, such as a hardwood floor, includes a base component and at least one colorant. The base component comprises an acrylic polymer and water, and the colorant is selected from the group consisting of a tint, a dye, and a pigment. The tinted coating is either a tinted tiecoat or a tinted spray buff. The tinted coating is used to improve the appearance of the hard-surfaced floor.
Abstract:
In the powder coating of wood substrates, there is the problem that on the one hand they must not become too hot and on the other hand the coating requires a certain temperature for crosslinking. With the known methods and devices, adequate crosslinking is not ensured. The object is to overcome this disadvantage. For this purpose, the freshly sprayed wood substrates (2) are pretreated by means of brief infrared radiation in such a way that the lacquer powder adheres to the wood substrates (2) and that the surfaces of the powder layer are pre-crosslinked. Then, the surfaces of the wood substrates (2) pretreated in this way are subjected to intensive hot air treatment, wherein the average temperature of the wood substrates (2) remains below 100° C.
Abstract:
The present invention describes a system for modifying polymer composite surfaces to achieve 100% adhesion to paints, coatings, adhesives, or inks. The adhesion modification technology overcomes the deficiencies of energy-based treatment technologies common with wood-like polymer composites produced using various types of fillers and reinforcements, and specifically those containing cellulose and lignin.
Abstract:
A method that conceals finish penetrating stains in wood flooring without the need for replacing the boards or stripping and bleaching the stain is provided by applying a whitewash mixture while maintaining visibility of at least a portion of the wood grain, preparing a masking mixture from a selected color pigmented component similar to a non-damaged area of the finish and a carrier, applying a coat of the masking mixture to the effected area while maintaining visibility of the wood grain, and applying a finish/sealer to the effected area.

Abstract:
The present invention discloses a method for manufacturing a flooring, in particular, to a method for manufacturing a multicolor antique wood flooring having an antique look and an embossed effect. It comprises the following steps: processing the raw material of the wood flooring to form an unvarnished flooring having the natural colors of lumber, and then performing water-based coloring with a dark color to the unvarnished flooring; drying; polishing; performing water-based coloring with a light color to the polished flooring; drying; applying a primer; drying; polishing; applying a top coat; and drying. Since coloring is performed for times in sequence in the manufacturing process, and the shades of the colors differ, and polishing are also performed for times, the places having different hardness in the wood grain present unevenness, and thus the wood flooring manufactured in this method has the advantages of having an embossed effect, many colors, different shades, irregular variations, and a strong sense of layers, as well as a prominent antique look and etc. and meanwhile, the level of the flooring is improved, which can cover the defects of low-quality flooring, and it is simple in processing, because the process of soaking coloring to the lumber in the manufacturing of conventional flooring is omitted.
Abstract:
Method for the thermal treatment of powder paints applied to substrates for the preparation of a coating on the substrates using IR radiation, wherein the powder paint which is applied to the substrate is radiated with middle- and/or long-wave IR radiation and the powder paint contains additives with the characteristic of absorbing middle- and/or long-wave IR radiation. Optionally, the powder paint which is thermally treated with middle- and/or long-wave IR radiation is subjected to a further treatment with electron or UV radiation.
Abstract:
An improved apparatus is provided for curing powdered coatings on the face of porous wood products, such as medium density fiberboard (MDF), wherein a pair of inclined infrared catalytic heaters are used to apply heat directly onto the side edges of the board. In addition, catalytic heaters that are normally used to heat and cure the face surface of the board are moved father back to reduce their effectiveness and to limit out-gassing of entrapped air from the inner low density core of the board. This arrangement also allows the coating to cure at the side edges of the board at approximately the same rate as the face of the board, promoting a more uniform curing of the powder coating.
