| Résumé : |
Water-based binders which make it possible to formulate low-solvent lacquers for wood are attracting more and more attention in the light of changing legislation, especially in Austria and Switzerland, and growing environmental awareness on the part of end users. Here, water-based acrylic dispersions are becoming increasingly important, being predestined for making low-solvent products. This article first compares the properties of conventional acrylic copolymer dispersions with those of dispersion blends and multi-stage polymers. Their minimum film forming temperature (MFT) and glass transition temperature (Tg) are investigated, as well as properties such as blocking resistance, pendulum hardness, elongation at break and mar resistance in waterborne clear lacquers. Also compared are the penetration resistance and depth of penetration of a dispersion and a conventional nitrocellulose lacquer, using the Fischerscope 100. |
