EF-909
EF-909 is a specially formulated epoxy resin which cures and expands at elevated temperature. It has good storage stability and produces superior bonds on composite materials to construct sandwich structure with light weight and high strength. EPF-909 could be co-cored with Prepreg or be pre-formed as core material, that depending on application and design. The Sandwich composite will not expand again at succeeding processes as compared to PU foam.
