Alkoxylated hydrophobes that include a poly(alkylene oxide) chain of at least 5 oxyalkylene units having a terminal secondary hydroxyl group or a terminal Chydrocarbyl group are effective internal mold release agents for epoxy resin moldings. The alkoxylated hydrophobe, when mixed with an epoxy resin, forms a mixture that is highly stable when heated to 80 to 100&#xb0; C. and held at that temperature for a period of as much as 22 days.

Epoxy resin compositions containing an internal mold release agent

A two-component curable epoxy resin system including a dye solution. 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 triethylene diamine in specific amounts as a catalyst. The system has beneficial curing characteristics with desired color that make it useful for producing fiber-reinforced composites in a resin transfer molding process.

Epoxy resin system for making carbon fiber composites

A two-component curable epoxy resin system having an epoxy component containing a unique combination of two or more epoxy resins with at least one of the epoxy resins being an epoxy novolac type resin. The composite made from such resin system exhibits high glass transition temperature.
