Coating composition providing gloss and opacity on application, having a pigment volume concentration of from 5% up to the critical pigment volume concentration and characterised in that comprises at least one ground natural calcium carbonate having a volume median diameter of between 0.05 and 0.3 &#x3bc;m, and at least one pigment having a refractive index of greater than or equal to 2.5.

Coating composition comprising submicron calcium carbonate and use thereof

The invention relates to a new atomizing device with improved droplet formation. Smaller droplets are formed with increased micronized volume throughput, wherein high volumes of air are fed to a liquid sprayed from a liquid nozzle (). High volume ratios result in mean free path between droplets being conveyed so as to minimize collisions and to prevent aggregation of the droplet.

Atomizing nozzle device, atomizing process and use

The present invention provides a process for preparing a precipitated calcium carbonate product. The process comprises the steps of preparing slaking quick lime to obtain slaked lime; and subjecting the slaked lime, without agitation, without prior cooling in a heat exchanger, and in the absence of any additives, to carbonation with carbon dioxide gas to produce PCC. The newly prepared product develops better performance thanks to improved resistance during processing.

Process for preparing scalenohedral precipitated calcium carbonate

A mineral composition comprising mineral particles, said mineral particles, when in a densely compacted bed form, having a volume defined median pore diameter from 0.01 to 0.04 micrometre, and having an intruded total specific void volume of 0.1-0.3 cm/g. A specific advantage of this composition is that it as a component in a coating, allows the passage of ink solvent into the base paper while retaining the ink molecules on the surface.

Mineral composition, especially for use in paper fillers and paper or plastic coatings

The present invention provides a process for preparing a precipitated calcium carbonate product. The process comprises the steps of preparing slaking quick time to obtain slaked lime; and subjecting the slaked lime, without agitation, without prior cooling in a heat exchanger, and in the absence of any additives, to carbonation with carbon dioxide as to produce PCC. The newly prepared product develops better performance thanks to improved resistance during processing.

A mineral composition comprising mineral particles, said mineral particles, when in a densely compacted bed form, having a volume defined median pore diameter from 0.01 to 0.04 micrometer, and having an intruded total specific void volume of 0.1-0.3 cm/g. A specific advantage of this composition is that it as a component in a coating, allows the passage of ink solvent into the base paper while retaining the ink molecules on the surface.

The present invention relates to the use of surface modified calcium carbonate as a filler in adhesives, sealants, and/or caulks, wherein the surface modified calcium carbonate is a mineral pigment product formed in situ by the double and/or multiple reaction between a calcium carbonate and the reaction product or products of the said carbonate with gaseous COformed in situ and/or coming from an external supply, and the reaction product or products of the said carbonate with one or more moderately strong to strong HOion donors, and at least one aluminum silicate and/or at least one synthetic silica and/or at least one calcium silicate and/or at least one silicate of a monovalent salt and/or at least one aluminum hydroxide and/or at least one sodium and/or potassium aluminate. It further relates to method of producing adhesives, sealants, and/or caulks comprising surface modified calcium carbonate, as well as to the adhesives, sealants, and/or caulks obtained by this process.
