A film-forming composition contains surface-treated nanocrystalline particles dispersed in a cross-linkable resin. A substantially transparent, abrasion- resistant film is formed from the film-forming composition. Processes for preparing the film-forming composition and for preparing a substantially transparent, abrasion resistant film are also included. The surface-treated nanocrystalline particles with one or more siloxane species, such as a siloxane stargraft polymer coating.
L'invention porte sur une composition filmogène contenant des particules nanocristallines traitées en surface et dispersées dans une résine réticulable. A partir de cette composition filmogène, on forme un film résistant à l'abrasion, pratiquement transparent. L'invention porte également sur des procédés de préparation de cette composition filmogène et d'un film résistant à l'abrasion, pratiquement transparent. Pour obtenir des particules nanocristallines traitées en surface, on les traite avec une espèce de siloxane telle qu'un revêtement polymère de siloxane greffé en étoile.
