A silicone dispersion, having improved toughness and thixotropic characteristics, cures to an elastomer upon exposure to the air. The dispersion is particularly useful for spraying onto exposed electrical conductors to prevent their shorting out from contact with animals and birds. The dispersion contains a hydroxyl endblocked polydimethyl-siloxane, aluminum trihydrate, moisture activated crosslinking agent and catalyst. In order to obtain thixotropy, it also contains a phenyl or 3,3,3-trifluoro-propyl-containing hydroxyl endblocked polydiorganosiloxane and untreated fumed silica. The method of making the dispersion is also specified.
