Abstract:
A sealant for sealing around one or more electrical conductors or conduits extending into a housing through an opening in a pad, comprising:a foam sealing material which expands in an unset state and which is flexible in a final set state, the foam being suitable for being positioned in the pad opening and sealing around a perimeter of the pad opening and around the conductors or conduits extending through the pad opening into the housing; a contact insecticide dispersed in the flexible foam sealing material for killing insects attempting to enter the housing, wherein the insecticide is selected from the group consisting of acephate, carbaryl, pyrenone, aldicarb and azinphos-methyl; and a fire retardant dispersed in the flexible foam sealing material to reduce the possibility of an electrical fault igniting the sealant and to minimize the amount of sealant which will burn if ignited.
