AQUEOUS PRIMARY DISPERSION, SUBSTANTIALLY OR COMPLETELY DEVOID OF VOLATILE ORGANIC SUBSTANCES, METHOD FOR THE PRODUCTION THEREOF AND USE OF THE SAME

摘要

The invention relates to an aqueous primary dispersion, substantially or completely devoid of volatile organic substances, containing dispersed and/or emulsified solid and/or liquid polymer particles and/or dispersed solid core-shell particles with a particle diameter ≤ 500 nm. Said dispersion is obtained by the radical micro- or mini-emulsion polymerisation of at least one olefinically unsaturated monomer, in the presence of at least one hydrophobic additive and at least one oligomeric polyester with a number average molecular weight of between 150 and 1,500 dalton, a hydroxyl value of between 100 and 1,000 mg KOH/g and an acid value 20 mg KOH/g. The invention also relates to a method for the production of said dispersion and to the use thereof as a coating substance, adhesive and sealant or for producing a coating substance, adhesive or sealant.
