Abstract
Mineral charge particles of silica or alumina are grafted with a hydrolysis product from a di- or trialkoxysilane whose functional group is compatible with an organic phase into which said grafted particles are ultimately incorporated. The grafted particles are separated from the aqueous hydrolysis medium by spray-drying. The organic phase comprising the grafted mineral particles is used to provide coatings with abrasion resistant properties.
