Disclosed herein are methods and items for flocking festive goods or holiday decorations, such as trees and wreaths, that reduce the loss of flocking material. The method can include applying a first glue emulsion onto an item, applying one or more layers of flocking material onto the glue emulsion, and applying one of: a second glue emulsion, an acrylic, or acrylic-like substance, over the one or more layers of flocking material. A decorative item can include one or more layers of flocking material, and a layer of: a glue emulsion, an acrylic, and/or acrylic-like substance applied on the one or more layers of flocking material.

The disclosure provides methods and compositions for coating substrates. A method of coating a substrate may include applying a formulation having a metal cation to a surface of the substrate to form a treated substrate, adding a solution having a biopolymer to the treated substrate, and allowing the biopolymer and the metal cation to react to form a coated substrate. The formulation may be applied to the substrate before the solution is added. A composition may include a reaction product of a biopolymer and a metal cation. The reaction product may be disposed on a coated substrate and the coated substrate may comprise a fibrous material.

A fan blade and a fabricating method thereof are provided. The fan blade includes a rough coating layer on a surface thereof. The rough coating layer includes a plurality of recessed regions. A maximum depth of recess of the recessed regions is between 50 μm to 130 μm.

A method for producing an abrasion-resistant wood-based panel with a top side and a bottom side. At least one decorative layer, in particular as a printed decoration, is provided on the top side. The method includes applying at least one first resin layer to the at least one decorative layer on the top side of the wood-based panel, uniformly scattering abrasion-resistant particles onto the first resin layer on the top side of the wood-based panel. The first resin layer on the top side of the wood-based panel provided with the abrasion-resistant particles is not dried after application. The method also includes applying at least one second resin layer to the first, moist resin layer provided with the abrasion-resistant particles on the top side of the wood-based panel, and then drying the assembly of first resin layer and second resin layer on the top side of the wood-based panel in at least one drying apparatus.

The present invention provides a multilayer coating film-forming method that is capable of forming a multilayer coating film with excellent finished appearance and excellent luster. The aqueous base paint (X) is applied by using a rotary-atomization bell-shaped coater under coating conditions of a shaping air pressure of 0.15 to 0.25 MPa and a paint discharge amount of 100 to 300 cm3/min. The viscosity 60 seconds after the application of the aqueous base paint (X), measured at a temperature of 23° C. and a shear rate of 0.1 sec-1, is 90 to 160 Pa.Math.s, the solids content 60 seconds after the application is 20 to 40 mass %, and the film thickness 60 seconds after the application is 17 to 35 μm. The effect pigment dispersion (Y) contains a flake-aluminum pigment (A) with an average thickness of 1 nm or more and less than 70 nm, a flake-aluminum pigment (B) with an average thickness of 70 nm to 250 nm, a hydroxy-containing acrylic resin (C), a rheology control agent (D), a surface-adjusting agent (E), and water, the effect pigment dispersion (Y) having a solids content of 2 to 9 mass %. The effect coating film after curing has a film thickness of 0.5 to 2.0 μm.
