The invention relates to aqueous formulations comprising silane-modified polymeric binders having a siloxane content and inorganic nanoparticles, a process for the preparation thereof and the use thereof for the preparation of aqueous coating compositions.

Silane-modified binder dispersions

The present invention relates to unblocked nano-particle-modified polyisocyanates having increased stability in the NCO content.

Stable polyisocyanates comprising nanoparticles

A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.

Method for separating an organic phase from an electrolyte-containing aqueous and organic phase

The invention relates to aqueous formulations comprising organic binders having a siloxane content and inorganic nanoparticles, a process for the preparation thereof and the use thereof for the preparation of aqueous coating compositions.

Siloxane-containing binder dispersions

Processes for preparing siloxane-modified polyisocyanates, the processes comprising: providing a polyisocyanate reactant; and reacting the polyisocyanate reactant with a hydroxyl-containing siloxane having a number-average molecular weight of 200 to 3000 g/mol and an average OH functionality of greater than or equal to 1.8, and corresponding to the general formula (I): wherein X represents an aliphatic, unbranched or branched Cto Cradical optionally containing ether groups; R represents a hydroxyl-functional radical; Rrepresents a hydrogen or an optionally heteroatom-containing Cto Chydrocarbon radical; and n is 1 to 40; siloxane-modified polyisocyanates prepared thereby, and uses therefor.

Polysiloxane-modified polyisocyanates, processes for preparing the same, and polyurethanes containing the same

The present invention relates to innovative, nanoparticle-modified polyisocyanates, a process for their preparation and to their use in coating compositions and adhesives. The process comprises the steps of 1) reacting A) polyisocyanates with B) alkoxysilanes, and subsequently 2) incorporating by dispersion inorganic particles, optionally surface modified, having an average particle size of less than 200 nm as determined by means of dynamic light scattering in dispersion, where the alkoxysilanes are according to formula (I)Q-Z&#x2014;SiXY&#x2003;&#x2003;(I)in which Q is an isocyanate-reactive group, X is a hydrolysable group, Y is identical or different alkyl groups, Z is a C-Calkylene group and a is an integer from 1 to 3.

Nanoparticle-modified polyisocyanates

Use of silica sols containing sulfonic acid groups and/or mercapto groups as microparticles in paper production, in particular for paper retention.

Paper production with modified silica gels as microparticles

A thermoplastic molding composition that features improved thermal stability and a relatively low maximum rate of decomposition in the event of fire is disclosed. The composition contains an aromatic polycarbonate and/or polyester carbonate, and a modified layered compound, the modification with organic polymer by means of a solvent-free melt process. Optional additional components include an impact modifier, a thermoplastic (co)copolymer, and a phosphorus compound.

Polycarbonate molding compositions

The present invention relates to innovative nanoparticles, to a process for preparing nanoparticles by recrystallization, and to the use thereof.

Process for preparing dispersible nanoparticles

Solvent-containing compositions based on polychloroprene, and solvent-containing zinc oxide dispersions which are stable in storage, that can be used in adhesive and sealant compositions. The compositions can be prepared by mixing the polychloroprene composition and zinc oxide dispersion and optionally adding conventional adhesive auxiliaries and/or additives and optionally adding an additional solvent.
