Coated abrasives suitable for very fine abrading applications can be obtained by depositing a layer of a formulation comprising abrasive grits, fillers, grinding aid, additives and a binder resin on a substrate, treating the formulation to increase the viscosity and render it plastic but non-flowing, embossing a suitable pattern on the surface of the layer, and then curing the binder component of the formulation.
Il est possible de produire des abrasifs sur supports, appropriés pour être utilisés dans des applications de très fine abrasion, en déposant sur un substrat une couche d'une formulation comprenant des particules abrasives, des charges de remplissage, des agents de meulage, des additifs et une résine liante, en traitant la formulation de façon à accroître sa viscosité et la rendre plastique, mais non coulante, bosseler une structure appropriée sur la surface de la couche, et durcir le liant de la formulation.
