Process to obtain an ultrafine GCC with high light scattering properties and high solid content

The present invention relates to a fiber board product comprising fibers in an amount from 50.0 to 99.0 parts by weight (d/d), at least one particulate calcium carbonate-containing material in an amount from 1.0 to 50.0 parts by weight (d/d), at least one binder in an amount from 0.05 to 25.0 parts by weight (d/d), at least one wax in an amount from 0 to 5.0 parts by weight (d/d), wherein the sum of the fibers and the at least one particulate calcium carbonate-containing material is 100.0 parts by weight (d/d), a process for manufacturing such a fiber board product as well as an use of at least one particulate calcium carbonate-containing material having a weight median particle size dof 0.5 to 150.0 &#x3bc;m as fiber replacement in a fiber board product, preferably in a high-density fiber (HDF) board, medium-density fiber (MDF) board, low-density fiber (LDF) board or particle board.

Fiber board product comprising a calcium carbonate-containing material

The present invention is directed to a liquid coating composition comprising at least one terephthalate ionomer comprising anionic substituents selected from sulfonate, carboxylate and/or phosphate groups, wherein the at least one terephthalate ionomer has an acid value of at least 1 mg KOH/g ionomer, at least one calcium carbonate containing filler, and a buffer.

Mineral oil barrier

The present invention consists of a process of preparation of at least one mineral matter and/or of at least one pigment, including a calcium carbonate made at once partially organophilic and partially hydrophilic, in which the carbonate is blended and/or ground and/or concentrated in an aqueous medium, in the presence of at least one salt of ethylene acrylic acid, one dispersing agent and/or one grinding aid agent, which is introduced before and/or during this treatment stage. Another object of the invention lies in the aqueous dispersions and suspensions of calcium carbonate thus obtained. They may be dried and the dry pigments obtained also constitute an object of the invention. Use of these aqueous dispersions and these dry pigments in the field of plastic, paints and paper constitutes another object of the invention.
