A process for subsequent surface modification of finely structured structures formed from hard inorganic materials, and the structures obtainable by this process as such. The structure has, in at least one spatial direction, a material thickness M of not more than 1000 nm and as an overall structure having, in at least one spatial direction, a measurement which is at least 5 times the material thickness M. The process includes treating the structures with an organic liquid under supercritical conditions.

Disclosed is an at least partly crosslinked coating (K) composed of a near-surface coating zone (K) and a volume coating zone (K), the coating obtained from a composition comprising at least two different crosslinkable components (D) and (D), at least part of component (D) having one or more surface-active structural units, wherein (i) the coating both in zone (K) and in zone (K) is at least partly crosslinked, and (ii) the crosslinking density of the coating in zone (K) is higher than the crosslinking density of the coating in zone (K). Also disclosed are coatings (K) wherein the concentration of component (D) in the near-surface coating zone (K) is higher than in the volume coating zone (K), and the micropenetration hardness and/or the dry scratch resistance of the coating (K) is higher than that of an at least partly crosslinked coating (K') obtained from a composition with no crosslinkable component (D).

Highly scratch-resistant coatings having good weathering and crack resistance

The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound and by reaction of a calcium compound with a silicon dioxide containing component under alkaline conditions, in both cases the reaction being carried out in the presence of a polycondensate containing at least one structural unit consisting of an aromatic or heteroaromatic moiety bearing a polyether side chain and at least one structural unit consisting of an aromatic or heteroaromatic moiety bearing at least one phosphoric acid ester group and/or its salt. The invention concerns a composition of calcium silicate hydrate and the polycondensate, its use as hardening accelerator and for the reduction of the permeability of hardened compositions.

The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound and a process for the preparation of a hardening accelerator composition by reaction of a calcium compound with a silicon dioxide containing component under alkaline conditions, in both cases the reaction of the water-soluble calcium compound with the water-soluble silicate compound being carried out in the presence of an aqueous solution which contains a water-soluble comb polymer suitable as a plasticizer for hydraulic binders. The invention concerns also a composition of calcium silicate hydrate and comb polymer, its use as hardening accelerator and for the reduction of the permeability of hardened compositions.
