The present invention has to do with an efficient system for coating and curing engineered wood products (EWP) in general, and the edges of EWPs in particular. An efficient system for coating and curing coatings is provided.

A method of treating a surface of wood products to inhibit the uptake of moisture into the wood by providing an aqueous formulation comprising polyethylene-vinyl acetate in water, 2-99 percent polyethylene-vinyl acetate by weight. The aqueous formulation is applied to the surface of wood products, wherein the wood products remain outdoors or in a damp environment having 60% or greater relative humidity. The aqueous formulation is allowed to dry and form a micro-film on the surface of the wood products. The moisture content in the wood products is maintained at 16 percent or less. A pesticide effect on the surface of the wood products is produced, inhibiting infestation of the wood products by insects.

A process for manufacturing a coated panel. The process can comprise providing a panel having at least an upper surface, a lower surface, and edges joining the upper surface and the lower surface. The panel can be arranged so that the lower surface is facing upwards, and first particles can be dispersed on the lower surface of the panel. The process can comprise turning the panel so that the upper surface is facing upwards, and applying first particles and second particles on the upper surface of the panel. A dcor can be applied in the form of a printed pattern to the upper surface. The process can further comprise curing and/or melting the first particles to form a sealed upper surface whereby the surface forms a coating providing at least one property of abrasion resistance and scratch resistance on the surface.

Disclosed is a method for printing a wood material board, in particular a wood fiber material board, by means of a digital printing process. The method includes the steps of (a) printing at least one side of a wood material board by means of digital printing technology, forming a decorative layer; (b) applying a protective layer containing at least one resin, at least one radiation-curable varnish and/or at least one polyurethane to the decorative layer of the wood material board; and (c) pre-drying and/or pre-gelling the protective layer applied to the decorative layer of the wood material board.

Disclosed are methods of protecting porous substrates and/or increasing the peel-resistance of coatings and stains for porous substrates. The methods may include providing a stain or coating comprising a microencapsulated self-healing material; and applying the stain or coating to a porous substrate. Damage to the stain or coating may release the self-healing material at a site of damage, such as a crack or scratch in the stain or coating. The self-healing material may be a polymeric precursor, .an unsaturated polyester resin or alkyd, a fatty acid-based natural oil or derivative thereof, or a cross-linkable silane or siloxane monomer or resin. The microencapsulated self-healing material may include a microcapsule having a shell wall that includes a thermosetting polymer or a thermoplastic polymer; the thermosetting polymer may include urea-formaldehyde, melamine formaldehyde, polyurethane, polyurea, or polyacrylate; and the thermoplastic polymer comprises poly(methyl methacrylate), poly(lactic acid), or poly(glycolic acid).
