This is an “RTV” (Room Temperature Vulcanization) product which is typically used to seal voids where moisture or insects could enter dwellings or structures. It sets up to form a semi-clear pliable filler. It is ideal for sealing around screw holes, drilled access holes for coax and other similar small void areas where a pliable gasket type seal would be prudent. This compound contains acidic compounds and should NOT be used in or on electrical connections or near electrical components or circuit boards.
