Abstract: A process for producing dip-coated articles in which a heated moulding with an electrolyte adsorbing surface is dipped into an aqueous latex preparation, the latex of which is stabilised substantially by emulsifiers with anionic sulphonate groups and is heat-sensitised by a silicon-organic tenside having non-ionic polyether groups and a cloud temperature in the range from 30 to 40 DEG C.
