The invention relates to aqueous primary dispersions, containing dispersed and/or emulsified solid and/or fluid polymer particles and/or dispersed solid core-shell particles with a particle diameter <= 500 nm, which may be produced by radical micro- or mini-emulsion polymerisation of at least one olefinic unsaturated monomer (A), in the presence of at least one polyhydroxy functionalised cyclic and/or acyclic alkane, comprising 9 - 16 C atoms per molecule. The invention further relates to the use thereof in automobile production and repair painting, furniture painting and industrial painting, including coil coating, container coating and coating of electrotechnical components.
La présente invention concerne des dispersions primaires aqueuses, contenant des particules polymères en dispersion et/ou en émulsion, solides et/ou liquides, et/ou des particules noyau-couches solides, en dispersion, d'un diamètre particulaire <= 500 nm, pouvant être produites par polymérisation radicalaire, en microémulsion ou en miniémulsion, d'au moins un monomère oléfiniquement insaturé (A), en présence d'au moins un alcane polyhydroxyfonctionnel, cyclique et/ou acyclique, ayant de 9 à 16 atomes de carbone par molécule. La présente invention concerne également l'utilisation de ces dispersions primaires pour la peinture d'origine et la peinture de retouche sur une automobile, le vernissage de meubles et l'enduction industrielle, telle que l'enduction en continu de bandes, l'enduction de conteneurs, ainsi que le revêtement de composants électrotechniques.
