Abstract
Foamable compositions which exhibit reduced surface tack and better handling characteristics are obtained through the use of specific combinations of epoxy resins. One or more solid epoxy resins are utilized together with liquid and/or semi-solid epoxy resins. The compositions, which preferably contain hollow glass microspheres, are capable of providing foams which are useful in the manufacture of reinforced structural members.
