LAYERED PARTICLE ELECTROSTATIC DEPOSITION PROCESS FOR MAKING A COATED ABRASIVE ARTICLE
摘要
Disclosed is a method of applying particles to a coated backing. A first layer of particles is created over a second layer of particles on a support surface and the first layer of particles is different in at least one property from the second layer of particles. A coated backing is positioned above the first and second layer of particles. An electrostatic field is applied simultaneously to the first and second layer of particles such that the first layer of particles closer to the coated backing are preferentially attracted to the coated backing first before the second layer of particles.
