Abstract

Traitement de perles de verre qui permet de controler leur mouillabilité. Les perles sont revetues d'un mélange de substances comprenant une substance qui, si elle était seule, rendrait les billes hydrophobes tout en conservant leur caractère oléophile et une seconde substance qui, si elle était utilisée seule, rendrait les billes hydrophobes et oléophobes. Les perles traitées conviennent comme charge dans les polymères et en particulier, conviennent comme agent réfléchissant dans les peintures (par ex. peintures pour marques routières).
