  • Foamed polymer semiconductor composition and a method of producing thereof
    Patent number: 3956195
    Abstract: A foamed polymer semiconductor composition, characterized in that it has the following formulation, in weight parts:epoxy resin 100 electrically conductive black or graphite 10-60 polyethylhydridesiloxane 0.1-50 polyethylenepolyamine 10-25 organic solvent 0-50After mixing the above-mentioned components self-foaming of the composition takes place and then its hardening follows. The composition has electric specific resistance in the range of 10 to 10.sup.12 ohm.cm.The present composition will find wide application in civil and hydraulic engineering for plugging up cracks in concrete and reinforced concrete structures.
