More Information
Summary:The present invention relates to a composition comprising an aqueous dispersion of spheroidal particles having a mode particle size of from 10 to 30 µm. The spheroidal particles are useful as organic extenders, especially in below-critical pigmented coatings formulations, and provide coatings with improved stain removal properties. La présente invention concerne une composition comprenant une dispersion aqueuse de particules sphéroïdales de dimension particulaire modale de 10 à 30 µm. Les particules sphéroïdales sont utiles comme matières de charge organiques, en particulier dans les formulations de revêtements pigmentées sous-critiques, et offrent des revêtements présentant des caractéristiques améliorées délimination des taches.
