Résumé :	Dispersion or emulsion paints are formulated with a variety of chemically different types of binders, which in most cases can be classified as acrylic esters copolymers or vinyl ester copolymers. A suitable binder is necessary to give a high quality paint. Experiments on masonry paints in the PVC range of 35 to 55% show that after many years of outdoor exposure no significant difference between straight acrylic and acrylic/styrene copolymers can be found. More important is the optimisation of the pigment volume concentration and the pigment/extender combination than the type of the binder.
Note de contenu :	- Various acrylic copolymer dispersions with similar particle size - Paint formulations - Water is the main source of damage a coating - Neutralisation of binders with NaOH gives better WA and WVTR results - Outdoor weathering results - Colour changes due to outdoor exposure - Yellowing of acrylic based paints is not better than acrylic/styrene - Chalking due to out door exposure - TABLES : 1. Polymer dispersions (Tg = glass transition temperature) - 2. Paint formulations (solid contents of the paints : 58%) - 3. Results of laboratory tests made with paints of PVC 40% - 4. Results of laboratory tests made with paints of PVC 50% - 5. Results of laboratory tests made with paints of PVC 60% - 6. Dirt pick-up and polymer degradation/chalking of the paint - FIGURES : 1. Colour change of masonry paint at PVC 50% by outdoor exposure - 2. L-value of masonry paints at PVC 50% as function of outdoor exposure - 3. b-value of masonry paints at PVC 50% as function of outdoor exposure
