Abstract

L'invention concerne l'industrie des abrasifs. Feuille de doucissage constituée d'une feuille support flexible conformable 13 portant une matrice de résine microcellulaire 12 contenant des granules abrasifs qui, dans les conditions d'emploi et en présence d'un courant aqueux, forme une suspension de doucissage; préparation par revêtement d'une feuille support flexible conformable avec une composition constituée d'un liant liquide durcissable, de granules abrasifs de doucissage et d'une quantité de solvant compatible suffisante pour l'étalement en revêtement qui, après durcissement, forme une couche cellulaire libérant les granules abrasifs de doucissage à une vitesse déterminée dans les conditions d'emploi. Application notamment au doucissage des surfaces vitreuses grossierement meulées pour obtenir une finition superficielle permettant un polissage facile.
