A method of applying a hydrophobic film to a surface, the method comprising the steps of (a) optionally modifying particles to be coated on the surface so as to form functional groups thereon; (b) applying particles having functional groups thereon to the surface to be coated; and (c) treating the applied particles such that the particles are bound together and to the surface by chemical cross-linking of the functional groups on the particles. The method may further include the addition of a non-silicone polymer to the particles prior to step (b) to assist in the formation of the film.
L'invention porte sur un procédé d'application d'un film hydrophobe sur une surface, ce procédé consistant à: (a) modifier éventuellement sur la surface des particules devant être enrobées de façon à former sur cette surface des groupes fonctionnels; (b) appliquer de particules possédant des groupes fonctionnels sur la surface à recouvrir; et (c) traiter les particules appliquées de sorte qu'elles soient liées entre elles et à la surface par réticulation chimique de leurs groupes fonctionnels. Le procédé peut également consister à ajouter aux particules un polymère sans silicone avant l'étape (b) de façon à faciliter la formation du film.
