A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 2 m N/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 m N/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.

In a method of coating a particulate material, a particulate material is fed into a mixing chamber. The particulate material is agitated within the mixing chamber and conveyed to a mixing chamber outlet. A coating is directed into the mixing chamber and the flow of the coating is controlled based on the volumetric flow rate of the particulate material into the mixing chamber. The coating includes at least one compound selected from herbicides, insecticides, nutrients, wetting agents, surfactants, fungicides, biologicals, inoculants, and mixtures thereof.

The present invention relates to a panel, in particular a wall, ceiling or floor panel, comprising a carrier layer made of a plastic material and a priming coat, wherein the priming coat comprises thereon an imprinted decorative pattern. Furthermore, the present invention relates to a method for manufacturing such a panel and a usage of a specific primer in such a panel.

A device (1) for introducing a plugging compound (20) into a borehole (21), the device having a sleeve (2) with a cavity (3) for receiving the plugging compound (20). On one side, the sleeve (2) has a discharge opening (5), corresponding to the cavity (3), for discharging the plugging compound (20), and a support section (7), projecting laterally from the sleeve, for providing a support option for the sleeve (2) during introduction of the plugging compound (20). On the opposite side of the sleeve (2), an upper opening (4) is provided, through which a piston (16) together with a feed plate (18) protrudes into the cavity (3). The piston (16) is movable relative to the sleeve (2) in such a way that the feed plate (18) can be displaced in the cavity (3), for example to allow the plugging compound (20) to be received and dispensed.

The present application relates to a process for treating a lignocellulosic material with at least one polyorganosiloxane compound, the polyorganosiloxane compound comprising a polyorganosiloxane backbone and at least one ammonium group residue of formula (I):

##STR00001## wherein R.sup.2, R.sup.3, R.sup.4 independently from each other signify linear, cyclic or branched, saturated or unsaturated, substituted or unsubstituted C.sub.1 to C.sub.45 hydrocarbon residues optionally including one or more hetero atoms of O, S, N, signifies the binding site linking to the polyorganosiloxane backbone.

A composition for sealing/coating the edges of wood-fibre boards is provided. The composition includes at least one compound of general formula R.sup.1.sub.aSiX.sub.(4-a) (I), and/or their hydrolysis products. X is H, OH or a hydrolyzable group selected from alkoxy-, aryloxy-, and acyloxy-, R.sup.1 is an organic radical selected from the group including alkyl, aryl, and cycloalkyl, and R.sup.1 has at least one functional group Q.sub.1 selected from a hydroxy, amino, monoalkylamino, carboxy, mercapto, alkoxy, aldehyde, acrylic, acryloxy, methacrylic, methacryloxy, cyano, isocyano and epoxy group, and a=0, 1, 2, 3, The composition also includes at least one compound of general formula R.sup.2.sub.bSiX.sub.(4-b) (II), and/or their hydrolysis products.
