STABLE CURABLE EPOXY RESIN COMPOSITIONS AND USES THEREOF

摘要

The invention belongs to the field of epoxy resin curable compositions, more particularly intend for the impregnation of fibers applicable to the manufacturing of composite structures and as adhesives thereof. The objects of the present invention are achieved by a curable or polymerizable epoxy resin characterized in that the hardener part comprises a combination of: (i) at least a liquid carrier, (ii) dicyandiamide and (iii) an amine functional catalyst the amount of the hardener over the epoxy resin being 8 to 20 part by weight, the operating window of the composition being between 12 hours to 30 days at room temperature.
