  • 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
