Abstract: A method for coating surfaces by treatment with a substantially paraffin-free aqueous formulation, comprising (A) at least one copolymer having a melt flow rate (MFR) in the range from 1 to 50 g/10 min, which comprises, incorporated in the form of polymerized units, (a) from 65 to 84.5% by weight of ethylene, (b) from 25.5 to 35% by weight of at least one ethylenically unsaturated carboxylic acid, and which is at least partly neutralized with alkali metal, (B) at least one nonionic or anionic surfactant, (C) at least one antifoam, (D) if appropriate, at least one organic amine, (E) if appropriate, at least one organic solvent.
Abstract: The invention relates to an adhesive or sealant comprising at least (A) 10% to 90% by weight of a compound selected from the group consisting of polyurethanes, polyureas, polyacrylates and polysulphides and at least (B) 1% to 50% by weight of a cyclohexanepolycarboxylic acid derivative, the adhesive or sealant containing no C4 to C8 alkyl terephthalate. The composition features a low glass transition temperature and also a low dirt pick-up tendency, without detriment to the further performance properties. An additional advantage of the proposed adhesives and sealants lies in their well-balanced mechanical properties. A process for preparing them, and their use for material bonds between parts to be joined, are disclosed.
