In one embodiment is provided a method of making an abrasive backing having a smooth surface comprising the steps of providing a paper having a first paper surface and a second paper surface; applying a first synthetic polymeric layer comprising a first synthetic polymeric composition to the first paper surface; and applying a second synthetic polymeric layer comprising a second synthetic polymeric composition to the first synthetic polymeric layer. The method is used to prepare fine abrasive backings having a smooth exterior surface for preparation of fine abrasive papers.
L'invention concerne, dans un mode de réalisation, un procédé de fabrication d'un support abrasif à surface lisse, qui consiste à fournir un papier ayant une première et une seconde surfaces de papier; à appliquer à la première surface de papier une première couche polymère synthétique comprenant une première composition polymère synthétique; et à appliquer à la première couche polymère synthétique une seconde couche polymère synthétique comprenant une seconde composition polymère synthétique. Ledit procédé permet de préparer des supports abrasifs présentant une surface extérieure lisse pour la préparation de papiers abrasifs fins.
