Two polysulfide-epoxy compound cable repair kits were investigated. The processability of the two part resin components was investigated over the ambient temperature range of -65 to 100 F, exothermic temperatures resulting from the reaction between the components were measured and protection of spliced MIL-C-13777 cable against damage by mechanical abuse twist and impact over an ambient temperature range of -65 to 125 F was determined. Under the conditions of this investigation, precondition-mix-pour at 70 and 100 F and precondition at 70-90 F -mix and pour at 0 and 25 F, both polysulfide-epoxy resin splice repair systems were effective in protecting latex rubber, extruded rubber, polyethylene and nylonpolyethylene insulated multiconductor cable repairs against mechanical abuse over the temperature range of -65 to 125 F. The potted splices exhibited electrical properties equal to or better than the basic cable and the compounds were effective in maintaining an adequate seal against moisture penetration and in maintaining excellent dielectric integrity under the mechanical abuse tests.
