  • Compositions useful for non-cellulose fiber sizing, coating or binding compositions, and composites incorporating same
    Patent number: 8791195
    Abstract: Disclosed is a toughened film forming agent for use in a fiber sizing, a finish coating or a binder composition, where the toughened film forming agent includes a film forming polymer and a toughening agent both dispersed in water. The toughening agent may be core shell polymers, rubber, thermoplastic materials, nanomaterials, nanofibers, including any combination or subset thereof. The film forming polymer may be epoxy resins, polyurethane resins, epoxy-polyurethane resins, polyester resins, epoxy-polyester resins, polyvinylacetate resins, polypropylene resins, including any combination or subset thereof.
    Type: Grant
    Filed: February 26, 2010
    Date of Patent: July 29, 2014
