  • Aromatic cyanate ester silane coupling agents
    Patent number: 6217943
    Abstract: A composition of matter comprises an aromatic cyanate ester silane comprising at least one cyanate ester group and at least one hydrolyzable silyl group. In the presence of a cyanate ester resin the aromatic cyanate ester silane acts as a coupling agent to improve the adhesion of the cyanate ester to a substrate. The curable compositions are useful as reinforced composites, and as adhesive and coating compositions.
    Type: Grant
    Filed: April 5, 1999
    Date of Patent: April 17, 2001
    Assignee: 3M Innovative Properties Company
    Inventors: Joyce B. Hall, Fred B. McCormick, Kim M. Vogel, Hiroyaki Yamaguchi

  • Cyanate ester adhesives for electronic applications
    Patent number: 5143785
    Abstract: The present invention provides an adhesive composition that is useful as an energy-curable, one-part adhesive, suitable for bonding electronic components. The adhesive composition, preferably provided as an adhesive film, comprises the reaction product of an admixture of an effective amount of a curable cyanate ester resin, a thermoplastic polymer, and a curing catalyst. The catalyst may be, for example, thermally or photochemically activated.
