Disclosed are compositions of fillers coated with adhesion promoting material alone, or also coated with an additive, processes for producing the coated fillers, the fillers obtained from those processes, and methods of using the coated fillers. The filler particle(s) are surface-treated with a component which assists in the adhesion/adherence of an additive to the filler particles, resulting in the desired additive-coated fillers. The filler, adhesion promoting material and additive can be mixed in slurry and dried, and the resulting filler particles are directly useful in many applications, such as paper coatings, plastic compositions (both foamed and non-foamed), inks, paints, cosmetics, textiles and the like, wherever such fillers now find application. Preferably, the additive is a colorant.

The present invention relates to an aqueous suspension of mineral pigment materials having high solids content, which contain dispersing agents and/or grinding agents based on renewable sources, and methods for preparing such a suspension and its use.

A dry liquid, comprising at least one additive having a molar mass greater than 20 g/mol, a melting temperature less than 500 C., and a boiling point, measured at 101325 Pa, greater than 100 C. and at least one calcium carbonate as a carrier material, wherein the calcium carbonate is precipitated calcium carbonate. The dry liquid is suitable in particular for introducing at least one preferably fluid additive into a chemical composition.

Disclosed are compositions of fillers coated with adhesion promoting material alone, or also coated with an additive, processes for producing the coated fillers, the fillers obtained from those processes, and methods of using the coated fillers. The filler particle(s) are surface-treated with a component which assists in the adhesion/adherance of an additive to the filler particles, resulting in the desired additive-coated fillers. The filler, adhesion promoting material and additive can be mixed in slurry and dried, and the resulting filler particles are directly useful in many applications, such as paper coatings, plastic compositions (both foamed and non-foamed), inks, paints, cosmetics, textiles and the like, wherever such fillers now find application. Preferably, the additive is a colorant.

A process for the preparation of a mineral filler product is disclosed, the process comprising a step of dry grinding a calcium carbonate-containing material in a mixture obtained by contacting the calcium carbonate-containing material with at least one grinding agent selected from specific styrene-maleic anhydride co-polymers and/or specific derivatives of styrene-maleic anhydride co-polymers.

The present invention relates to a process for the production of a mineral filler product comprising a step of dry grinding a calcium carbonate-containing material in the presence of an agent being a polyol. The mineral filler product according to the present invention was found to have a reduced moisture pickup as compared to prior art products.

The present invention relates to a process for the manufacturing of a calcium carbonate-comprising material, a calcium carbonate-comprising material obtained by a process as well as the use of the calcium carbonate-comprising material for paper filler and paper coating applications, cigarette paper applications, for plastics applications or in paints, coatings, adhesives, replacement of titanium dioxide, preferably in paints, sealants, food, feed, pharma, concrete, cement, cosmetic, water treatment and/or agriculture applications.

The present invention relates to a process for manufacturing a decorative wood-based board, to a decorative wood-based board, to the use of at least one dry or liquid coating composition comprising at least one inorganic particulate filler material and at least one binder for in-line coating of decorative wood-based boards, and to the use of at least one dry or liquid coating composition comprising at least one inorganic particulate filler material and at least one binder for improving the mechanical properties of a decorative wood-based board. Furthermore, it relates to the use of a decorative wood-based board in flooring applications, furniture, walls, roof panels, display cabinets, storage units, loudspeakers and shop-fittings.

The present invention relates to an installation for the purification of minerals, pigments and/or fillers and/or the preparation of precipitated earth alkali carbonate and/or mineralization of water and to the use of such an installation for the purification of minerals, pigments and/or fillers and/or mineralization of water and/or the preparation of precipitated earth alkali carbonate.

The present invention relates to a process for preparing an aqueous suspension comprising precipitated calcium carbonate. The invention further relates to an aqueous suspension comprising precipitated calcium carbonate as well as a partially dewatered or essentially completely dried precipitated calcium carbonate obtainable by the process and the use of the aqueous suspension comprising precipitated calcium carbonate and/or the partially dewatered or essentially completely dried precipitated calcium carbonate in paper making, paper coating, plastic, agricultural, adhesives, sealants and/or paint applications.
