Building panels with a homogenous decorative surface having a wear layer comprising fibers, binders and wear resistant particles.

A method, a panel and equipment to form a digital print by applying dry ink (15), preferably including particles of pigment coated wood fibers (61), on a surface (2), bonding a part of the particles with a liquid blank ink drops (57) and removing the non-bonded particles from the surface (2).

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colourants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colourants (7) and removing non-bonded dry ink (15) from the surface (2).

Various examples are provided for polymer reinforced composite plywood and laminates. In one example, among others, polymer reinforced composite plywood includes a multilayer polymeric film bonded to a first ply of wood veneer and a second ply of wood veneer. A second multilayer polymeric film can be bonded to the second ply of wood veneer and to a third ply of wood veneer. In another example, polymer reinforced composite plywood includes a monolayer polymeric film bonded to a first ply of wood veneer and to a second ply of wood veneer. A second monolayer polymeric film can be bonded to the second ply of wood veneer and to a third ply of wood veneer. In another example, low pressure laminate includes a polymeric film layer bonded to a base layer that forms a protective lamination layer over the base layer.

Pigment based particles in powder form intended to be used as colourants in a digital print formed by applying dry colourants on a surface, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. A panel with a surface including a digitally formed print of macro colourants including a particle body and colour pigments attached to the surface of the particle body is also described. The colourants are arranged in patterns with pigments on an upper and lower surface of the particle body.

An engineered wood panel assembly includes a first layer including a first set of billets that abut against each other along a lengthwise edge of the billets. Each billet includes one or more joints connecting adjacent sheets within the billet, and the joints are oriented perpendicular to the lengthwise edge. Each of the sheets in the first layer includes at least one ply comprising wood grain oriented in a first direction. A second layer including a second set of billets of sheets is layered on top of the first layer. Each billet in the second set includes one or more additional joints that are oriented perpendicular to a lengthwise edge of the second set of billets. The additional joints in the second layer are offset from the joints in the first layer, and each of the sheets in the second layer includes at least one ply having wood grain oriented in a second direction. Additionally, a third layer including a third set of billets of sheets may be layered on top of the second layer.

Provided are adhesive materials for fire resistant applications, methods of using these adhesive materials on lignocellulosic and other like substrates, and composite materials including lignocellulosic substrates and these adhesive materials. In addition to being fire-resistant, the composites formed from the substrates and adhesive materials may be also durable to moisture. The adhesive materials may include at least one proteinaceous-containing material and at least one magnesium oxychloride material. Other materials may be present as well, in some embodiments. For example, an adhesive material may include a solvent or a vinyl polymer. In some embodiments, water may be used as a solvent and the adhesive material may be referred to as an aqueous adhesive material. Some examples of suitable vinyl polymers include but are not limited to polyvinyl alcohol (PVOH), polyvinyl acetate (PVAc) and vinyl acetate/ethylene (VAE).
