Abstract: The invention relates to a copolymer which contains at least one polysiloxane group and the skeletal structure of which is an addition compound of at least one amine and at least one epoxide. The invention further relates to the use of said products as additives in coating agents, plastics, or homogeneous dispersions, e.g. as a dispersing agent for organic and inorganic pigments and fillers in oil-based compositions, or as a surface modifying agent.

Abstract: The invention relates to a method for producing particulate composite materials. According to the method, solid inorganic or organic particle agglomerates or particle aggregates that are provided in a dry state, particularly in powder form, are first reduced in size in the gas phase or in a gaseous carrier medium in the presence of organic matrix particles by applying energy. The obtained comminuted particles are dispersed into the organic matrix particles, especially embedded thereinto and/or attached thereto. The composite materials produced in said manner can be used in many different ways and are suitable in particular for use in a large variety of plastic materials, coating materials, paints, and lacquers, especially coating powders, to modify properties during use in the corresponding products and similar.

Abstract: The invention relates to the use of copolymers which as well as other monomers contain in copolymerized form 10% to 90% by weight of monomers containing heterocyclic basic groups, and which do not contain vinylpyrrolidone as a monomer component, as additives in paints for improving the adhesion of the solid paint film to a substrate. The invention also relates to cured and uncured polymer compositions comprising copolymers which as well as other monomers contain in copolymerized form 10% to 90% by weight of monomers containing heterocyclic basic groups, and which do not contain vinylpyrrolidone as a monomer component, as adhesion improver additions.

Abstract: The invention relates to addition compounds which are obtainable by reacting a) one or more polyisocyanates containing uretdione groups with b) one or more compounds of the formula (I) Y—(XH)n??(I) with the proviso that at least 50% of the free isocyanate groups of component a) are reacted with the compounds of the formula (I) to give an intermediate which contains uretdione groups, and subsequently the intermediate is reacted with c) one or more compounds of the general formula (II) Z—NHRm??(II) with the proviso that all free NCO groups optionally still present and at least 20% of uretdione groups originally used are reacted with Z—(NHR)m. The invention further relates to the use of the addition compounds as dispersants and dispersion stabilizers, and to a process for preparing them.

Abstract: The invention relates to powder coating leveling agents comprising (a) at least one polypropylene oxide-containing polyether having a weight-average molecular weight of more than 1000 g/mol and a polypropylene oxide fraction of more than 75% by weight, and optionally (b) at least one poly(meth)acrylate. The invention further relates to the preparation of such leveling agents and to their use in powder coating materials, and also to powder coating materials comprising the leveling agents.
