The invention relates to aqueous dispersions, characterized in that they comprise (c) at least one aqueous silicon dioxide dispersion with a mean particle diameter of the SiO-particles of 1 to 400 nm and (d) at least one water-soluble hydroxyl-containing organic compound, to a process for their preparation and to their use in adhesive and coating formulations.

Aqueous silicon dioxide dispersions for sealant and adhesive formulations

Aqueous polymer dispersions based on polychloroprene, a process for their preparation and their use in adhesive formulations. The aqueous polymer dispersion is obtained by

Aqueous adhesive dispersions

An aqueous polymer dispersion that includes a) a polyurethane dispersion having an average particle size of 60 to 350 nm and b) an aqueous silicon dioxide dispersion having a particle diameter of the SiOparticles of 20 to 400 nm. The dispersion is prepared by mixing the polyurethane dispersion (a) with the silicon dioxide dispersion (b). The aqueous polymer dispersion can be used in adhesive compositions, which can be used to bond substrates together, especially substrates that are structural components of shoes.

Aqueous polymeric dispersions comprising a mixture of: (a) a component selected from the group consisting of polyvinylacetates, polyvinylacetate copolymers, and combinations thereof; and (b) SiOparticles having an average particle diameter of 1 to 400 nm; their use as adhesives and coatings; processes for preparing such dispersions; and substrates coated and/or adhered therewith.

The invention concerns hydrous compositions based on polychloroprene and hydroxylamine derivatives, processes for their production and their use as adhesives. The polychloroprene dispersions are stabilized by the addition of hydroxyalkylamine after removal of residual monomer.

Aqueous dispersions

Aqueous polymer dispersions based on polychloroprene, and a process for their preparation and use. The aqueous polymer dispersions are produced from a polychloroprene dispersion having an average particle size of from 60 to 220 nm, and an aqueous silicon dioxide dispersion having an SiOparticle diameter of from 1 to 400 nm.

Polychloroprene dispersions containing particles of urea derivatives having a particle size in the range of 10 to 400 nm, which can be used in adhesive compositions. The adhesive compositions can be used to provide substrates containing adhesive layers obtained from the compositions.

Dispersions

Water-containing compositions containing polychloroprene particles, zinc oxide particles having an average particle size of less than 150 nm and water. The compositions can be used as adhesives and/or sealants.

Aqueous compositions based on polychloroprene

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.
