- the entry be made into a composition comprising less than 100% by weight of water or at least one polar organic solvent or a mixture containing water and at least one polar organic solvent, based on the total mixture. %, for example, at a level of 80, 60, 40, 20 or around 10% by weight only.
- the proportion lacking 100% by weight may comprise, for example, oligomeric or polymeric ingredients or other auxiliaries, fillers and the like, as contained, for example, in coating compositions such as emulsion paints or water-based paints.
- mechanical force action is understood to mean a measure resulting in a movement of the mixture of water and solid powder, which is preferably sufficient to form a complete dispersion within 60 minutes suitable stirring devices, Ultraturrax, dissolver disc or other methods such as ultrasound.
- a "complete dispersion” is understood as meaning a state in which the solid powder is substantially completely wetted in the water and no water is present even after a service life of at least one minute, preferably at least 5 minutes or at least 1 hour settle unwetted particles.
- a core-shell structure is understood to mean a structure in which the composition of the solid particle, starting from the center of the particle, changes towards the edges in such a way that the edge has a different composition than the center , Such changes may be made in the context of the present invention continuously or substantially discontinuously or as a mixture of both phenomena.
- the term "predominant core-shell structure” is understood to mean that the core-shell structure can be detected for at least about 40% of the surface of the solid-state fluid Electron microscopic examination of the Feststoffieil- Chen done.
- a solid powder according to the invention comprises particles having an average particle size of about 0.1 to about 50 ⁇ m, for example about 0.5 to about 30 or about 1 to about 20 ⁇ m. Suitable methods for determining the particle size are known to the person skilled in the art, the laser diffractometry being particularly mentioned here.
- the individual particles of a solid powder of the invention comprise a core consisting of a core material containing at least one water-insoluble fatty acid salt.
- the core itself may consist, for example, of a corresponding water-insoluble fatty acid salt or a mixture of 2 or more fatty acid salts, of which at least one must be water-insoluble, or a mixture of a water-insoluble fatty acid salt and one or more further compounds.
- the core itself already has a core-shell structure.
- the core used is a structure which in turn has as its core an inorganic or organic carrier, for example a filler such as chalk or titanium dioxide, which has on its surface a corresponding water-insoluble fatty acid salt.
- an inorganic or organic carrier for example a filler such as chalk or titanium dioxide
- Such structures have the advantage that in many cases they require a significantly reduced proportion of expensive fatty acid salts with identical effectiveness with respect to the hydrophobing effect and are thus significantly more economical.
- Such core structures are used in particular in systems in which the thermal load does not exceed the melting point of the fatty acid salts or of the fatty acid salt used.
- the core comprises an inorganic or organic carrier material which has a porous, for one or more further ingredients of the core material, for example absorbent structure.
- Suitable materials are e.g. Zeolites or layered compounds such as hydrotalcites and the like.
- the core material of a solid powder according to the invention therefore contains at least one organic or inorganic carrier material.
- Suitable fatty acid salts in the context of the present invention are the salts of the aliphatic carboxylic acids of the formula (I) R 1 CO-OH (I)
- R CO is an aliphatic, linear or branched acyl radical having 6 to 22 carbon atoms and 0 and / or 1, 2 or 3 double bonds.
- Suitable fatty acids are caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidic acid, gadoleic acid, Behenic acid and erucic acid and their technical mixtures, eg in the pressure splitting of natural fats and oils, in the reduction of aldehydes from the Roelen oxo synthesis or the dimerization of unsaturated fatty acids.
