Coated abrasives is a three component system consisting of abrasive grains adhering to the semi-flex backing like paper, cloth, fibre, plastic film etc with the help of resin or glue bond. CUMI specialize in manufacturing of a complete line of closed sized abrasive grains in various shapes, sizes and densities, etc. to perfectly fit any coated abrasive application and working condition.
CUMISHARP Grains for coated abrasives are angular, sharp edged with high capillarity for instant adhesion to resin or glue bonds and electrostatic characteristics carefully monitored to provide consistent and reliable grain projection. The High hardness and toughness of the CUMI Sharp grains combined with the multi-fracturing property, self-sharpening characteristics and cooler cutting characteristics of the grains makes it an ideal raw material for the manufacturing of coated abrasives for any application.
