ABSTRACT:
The viscosities of solventless compositions of epoxy resins containing 1, 2 epoxy groups and having at least two epoxide groups per molecule and effective amounts of catalytic hardener and phenolic accelerator are dramatically reduced to make them useful for vacuum-pressure impregnation and also for pre-impregnated insulating material applications by addition of 3-33% of reactive diluent such as styrene.
