FORMULATIONS FOR COATED DIAMOND ABRASIVE SLURRIES |
摘要 |
<p>The present invention is directed to an abrasive article and methods of making the abrasive article. An abrasive coating on the abrasive article comprises at least 20% by weight of a superabrasive particle. The abrasive coating is derived from an abrasive slurry. The abrasive slurry may comprise and a dispersant having an AV wherein AV = 1000*[(Amine Value)/(Mw)]. The dispersant comprises a polymer having a molecular weight (Mw) of greater than 500g/mol and an AV of greater than 4.5, a polymer having a molecular weight (Mw) of greater than 10,000g/mol and an AV of greater than 1.0, or a polymer having a molecular weight (Mw) of greater than 100,000g/mol and an AV of greater than 0.</p> |
