  • Patent number: 11078358
    Abstract: The present disclosure provides a curable composition. The curable composition includes a liquid epoxy resin component a curative component, and a curable resin filler component. At least a portion of curable resin filler is dispersed in the liquid epoxy resin and solid at about 25° C. According to various examples, the curable composition can produce a film having good tackiness and improved handling characteristics. Additionally, according to some examples, a cured product of the curable composition can have a Wet Glass Transition Temperature and a Dry Glass Transition Temperature that are substantially the same.
