  • Abrasive product coated with agglomerated particles formed in situ and method of making the same
    Patent number: 9586308
    Abstract: The present invention relates to a coated abrasive article containing abrasive agglomerates based on target cores that provide an extended surface. Target cores are defined as geometric shapes, e.g., spherical, rectangular, tetrahedral, conical, cylindrical, pyramidal or combinations and mixtures thereof. The preferred cores are porous structures with their own abrasive capacity as a grinding aid element. They are bonded on substrates, e.g., textile fabrics, plastic films, saturated or no treated papers, vulcanized fibers, non-wovens and mixtures thereof to produce extended surfaces on which are deposited the working abrasive particles, e.g., aluminum oxide, silicon carbide, zirconia alumina, ceramic aluminum oxide and mixtures thereof, through an electrostatic field to improve performance capabilities. The electrostatic field promotes orientation of the deposited grains around the cores with exposed sharp edges over the extended area, causing as a secondary effect the compacting of the abrasive grains.
