  • Method of treating a surface, surface-modified abrasive particles, and resin-bond abrasive articles
    Patent number: 11697753
    Abstract: An adhesion promoter comprises a reaction product of: a) a polyepoxide; b) an aminosilane represented by the formula HNR1R2. R1 and R2 independently represent —Z—SiL3. Each Z independently represents a divalent linking group having from 1 to 12 carbon atoms, and each L independently represents a hydrolyzable group; and c) an isocyanatosilane represented by the formula O?C?N—Z—SiL3, wherein Z and L are as previously defined. The adhesion promoter may be used to treat a surface of a substrate such as an abrasive particle, which may be included in a resin-bond abrasive article.
    Type: Grant

    Date of Patent: July 11, 2023
    Assignee: 3M Innovative Properties Company
    Inventors: Hae-Seung H. Lee, Melissa C. Schillo-Armstrong, Babu N. Gaddam
  • Adhesion promoters for curable compositions
    Patent number: 11168237
    Abstract: Adhesion promoters, Curable compositions containing the adhesion promoters, cured compositions that are formed from the curable compositions, and articles containing the cured compositions are provided. The adhesion promoter has at least one epoxide group and a plurality of hydrolyzable silyl groups. The curable compositions include an adhesion promoter, an epoxy resin, and a curing agent for the epoxy resin that has at least two amino groups that are primary and/or secondary amino groups.

  • METHOD OF TREATING A SURFACE, SURFACE-MODIFIED ABRASIVE PARTICLES, AND RESIN-BOND ABRASIVE ARTICLES
    Publication number: 20210246345
    Abstract: An adhesion promoter comprises a reaction product of: a) a polyepoxide; b) an aminosilane represented by the formula HNR1R2. R1 and R2 independently represent —Z-SiL3. Each Z independently represents a divalent linking group having from 1 to 12 carbon atoms, and each L independently represents a hydrolyzable group; and c) an isocyanatosilane represented by the formula O=C?N—Z-SiL3, wherein Z and L are as previously defined. The adhesion promoter may be used to treat a surface of a substrate such as an abrasive particle, which may be included in a resin-bond abrasive article.
