  • Epoxy resin system containing polyethylene tetraamines for resin transfer molding processes
    Patent number: 9688807
    Abstract: A two-component curable epoxy resin system is disclosed. The resin system includes an epoxy resin component containing at least 80% by weight of a polyglycidyl ether of a polyphenol. The system also includes a hardener mixture containing mainly polyethylene tetraamines. The system includes one or more of i) alkali metal salts, ii) carboxylic acid-, carboxylic anhydride- or carboxylic acid ester-substituted phenol compounds, iii) an amino as a catalyst. The system has beneficial curing characteristics that make it useful for producing fiber-reinforced composites in a resin transfer molding process.

  • LOW ODOR EPOXY RESIN SYSTEMS BASED ON NADIC ANHYDRIDE-TYPE HARDENERS
    Publication number: 20160280864
    Abstract: Thermosets are formed by mixing an epoxy resin with a hardener composition that includes a norbornene-based anhydride hardener such as methyl nadic anhydride and a core-shell rubber. The presence of the core-shell rubber unexpectedly reduces the strong odor of that is normally produced in thermosets containing these anhydride hardeners.
