  • Curable epoxy resins
    Patent number: 4307212
    Abstract: Curable epoxy resin compositions which exhibit controllable cure rates are described which utilize catechol derived accelerators in combination with certain curing agents. These accelerators can be employed in single package curable epoxy resin compositions useful in molding and casting applications.
    Type: Grant
    Filed: August 14, 1980
    Date of Patent: December 22, 1981
    Assignee: General Electric Company
    Inventor: Charles J. Stark, Jr.
  • Curable epoxy resin compositions
    Patent number: 4307213
    Abstract: Diesters of catechol and ring substituted catechol exhibit enhanced characteristics as accelerators in the cure of epoxy resins when utilized in combination with a cure initiator, such as an oxygen titanate or zirconate.
    Type: Grant
    Filed: September 5, 1980
    Date of Patent: December 22, 1981
    Assignee: General Electric Company
    Inventor: Charles J. Stark, Jr.
  • Curable epoxy resin composition
    Patent number: 4297457
