Abstract: The invention relates to a soluble acrylate copolymer which can be obtained by copolymerization of more than 3 to 30% by weight, based on the total weight of all the monomers, of a monomer with at least 2 polymerizable, olefinically unsaturated double bonds, monomers which carry functional groups and other monomers with a polymerizable double bond, the acid number of the acrylate resin being 15 to 200. The invention furthermore relates to processes for the preparation of the acrylate copolymers and coatings based thereon and based on polyepoxides.

Abstract: The invention relates to a water-dilutable binder for cationic electrocoating finishes. For the preparation of the binders po0 (A) a di-epoxide compound with an epoxide equivalent weight below 2,000 is reacted with(B) a phenol- or thiol-containing compound which reacts monofunctionally with epoxide groups, and with(C) primary and/or secondary amines or their salts and/or the salt of a tertiary amine, a sulfide/acid mixture or phosphine/acid mixture or a mixture of these compounds, as well as, if desired, with(D) a polyfunctional alcohol, a polycarboxylic acid, a polysulfide or a polyphenol.The components A and B are used in a molar ratio of from 10:1 to 1:1, preferably from 4: to 1.5:1 and the reaction of the component A with the component B is carried out at 100.degree. to 190.degree. C., if desired in the presence of a catalyst.

Abstract: The invention relates to a device for filling transportable vessels with flowable materials in free fall, with a filler socket arranged on the top wall of the vessel, a first clamping ring which can be fastened removably to the filler socket, a second clamping ring which can be attached on the topside of the first clamping ring, and a flexible filler hose fastened at its respective ends to the first clamping ring and to the second clamping ring, the flexible filler hose being folded back inwards on itself in the region of the first clamping ring and having a weighting ring in its reversal region.

Abstract: The invention relates to water-dispersible binders which are intended for cationic electropaints and are based on reaction products which are formed from modified epoxy resins and primary and/or secondary amines and which can, if desired, also contain crosslinking agents, pigments, flow-control agents and other customary auxiliaries. They contain as reaction products those which have been prepared by reacting(A) low molecular weight epoxy resins which contain epoxy compound aromatic groups and have an epoxide equivalent weight of less than 375 with(B) aliphatic and/or alicyclic polyfunctional alcohols having hydroxyl groups or carboxylic acids having carboxylic groups and both having a molecular weight of less than 350 and addition of the hydroxyl groups and carboxylic groups to the epoxy groups of (A) in such a way that the reaction products of (A) and (B) contain 10-45% of aromatic groups, calculated as the phenylene group, and have terminal epoxy groups.

Abstract: The invention relates to water-dilutable binders for cationic electrocoating finishes, the said binders containing latent primary amino groups. In order to prepare the binders, an epoxy resin is reacted with a polyamine, which in addition to a sterically hindered primary amino group also contains at least one primary amino group blocked by reaction with a ketone or aldehyde, and, if appropriate, further primary or secondary amines.

Abstract: The invention relates to a process and an apparatus for applying two or more colors of paint by applying a first paint to at least part of a substrate, followed by a second and, if desired, further different-colored paints to different parts of the substrate and hardening the applied coats of paint by baking, which comprises applying the second and if desired the further different-colored paints without interim baking of the first paint to the preselected different parts of the substrate using electrostatic atomization at stationary atomizer edges involving transport of the paint particles in an electric field and, after the first and subsequent paints have been applied, hardening all coats of paint together by baking.

Abstract: The heat-hardenable binder mixture based on organic resins comprises an organic resin having primary and/or secondary and, if appropriate, also additional tertiary amino groups and a cross-linking agent based on an organic compound containing at least 2 carbalkoxymethyl groups. The binder mixture can additionally contain pigments, fillers, cross-linking catalysts, corrosion inhibitors and further finish auxiliaries. The binder mixture is used in a process for preparing coatings by applying a coating agent in the form of a film to a substrate and subsequently hardening the film by baking.
