Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

A method is provided for manufacturing a paper layer having a printed pattern for use in panels that at least include a substrate and a top layer. The top layer includes the paper layer. The method may involve providing the paper layer with an inkjet receiver coating by transporting the paper layer relative to a coater in a coating direction. The coated paper layer may be provided with at least a portion of the printed pattern using a digital inkjet printer that includes a housing containing print heads. Providing the printed pattern may involve using water based pigment containing inks. The printed pattern may include a wood motif having wood nerves extending generally in a nerve direction substantially corresponding to the coating direction. Providing the printed pattern may involve a relative motion between the digital inkjet printer and the paper layer during a printing operation in a printing direction substantially corresponding or substantially opposite to the coating direction. The paper layer may be maintained flat inside the housing, or the minimum radius over which the paper layer is bent inside the housing may be larger than 25 centimeters. The paper layer may be fed from a roll, printed upon, and rolled back up again.

The present disclosure relates to a method of coating a non-conductive substrate, said method comprising the steps of: a) applying a coating composition to the substrate, wherein the coating composition comprises: i) at least one unsaturated compound, ii) a thermal initiator comprising an organic peroxide, iii) a photoinitiator, and iv) at least one pigment, wherein the coating composition is free of accelerator, is capable of decreasing the activation energy of the thermal initiator, and is free of Co compounds, b) exposing the coating composition to UV light effective to start polymerization of the unsaturated compound, and c) exposing the coating composition to microwave heating effective to decompose the thermal initiator, wherein step c) is performed either simultaneously with step b) or sequentially after step b).

A method to manufacture, on one or more production or manufacturing lines, an integrated roofing product, such as a roofing panel or roofing plank. A blank panel of engineered wood is cut or sawn into a plurality of raw planks or raw panels, each with an outer face, an inner face, a top edge, and a bottom edge. Each raw plank or panel is then processed by cutting or routing a profile into the top edge, the bottom edge, or both; affixing a gasket seal to the profile in the top edge or the bottom edge, or both; coating at least some or all of the outer face with a silicone-based or silicone-containing coating; applying a mix of granules and/or sand to the silicone-based coating while wet; and curing the coated plank or panel. A plurality of panels or planks can then be installed on a roofing structure.

A curable resin composition may include a component having two or more active methylene groups and/or active methine groups, a component having at least two α,β-unsaturated carbonyl groups, and a triphenylphosphine catalyst that promotes a Michael reaction between the other two components. The composition can be used to coat metal substrates and can exhibit particularly good performance characteristics when applied to unprimed, bare metal surfaces.

The present invention relates to silica aerogels with a high to very high loading (55-90% w/w) of encapsulated biocidal and/or biorepellant compounds and very low thermal conductivity and to methods of making and using such aerogels in anti-fouling compositions, which are especially suitable for coatings (marine paints, coatings, sealants, lacquers, wood protection or similar controlled leaching systems) that are naturally exposed to humid conditions and/or water, including sea water, and thus prone to fouling.

Disclosed is a surface covering including: a wood-based substrate; a surface coating layer, the surface coating layer being obtained by the irradiation of a radiation-curable coating agent with UV light having a wavelength included from 120 nm to 230 nm; and a filler coating layer, the filler coating layer being located between the wood-based substrate and the surface coating layer. Also disclosed is a method for the manufacture of such a surface covering.
