Abstract

Preparing a dispersion of hydroxy-functional binder containing (non)ionic, hydrophilic and/or neutralisable acidic or basic groups, used as binders for aqueous two-component coatings or aqueous dispersions containing standard lacquer additives, comprises: (a) mixing the hydroxy-functional binder, optionally present in an organic solvent phase with at least some of the standard lacquer additives in a non-aqueous phase; (b) partially neutralising acidic or basic groups at least before, during or after mixing with the additive; (c) homogenising and converting the resulting mixture into an aqueous phase; and (d) degrading any excess additive remaining. The use of these dispersions as binders or for the preparation of binders for aqueous two-component coatings is also claimed. Preferably the additives include light protection agents, processing aids, thixotropic agents, thickeners, anti-foaming agents, wetting agents, skin formation prevention agents, anti-oxidants, anti-flocking agents, matting agents, adhesion promoting agents, structure additives, gloss improving additives, catalysts and solvents. Acidic and basic groups are neutralised by adding neutralising agent after the binder/additive mixture has been homogenised and then the at least partially neutralised binder mixture is re-homogenised. Homogenisation is carried out at elevated temperature. At least one pigment and/or filler are added at the same time as the additives.
