Abstract
A silicone septum having a surface coating. The coated silicone septum may be incorporated in an intravenous catheter assembly. The coating reduces static charge among a plurality of vibrating silicone septa during manufacture of the intravenous catheter assembly. The surface coating includes a coating agent selected from a bicarbonate salt and a siloxane polyalkyleneoxide copolymer. The bicarbonate salt may be an alkali metal bicarbonate. The siloxane polyalkyleneoxide copolymer may include copolymer groups selected from ethyleneoxide, octamethylcyclotetrasiloxane, and mixtures thereof. The silicon septum may be coated by contacting an exterior surface of the silicone septum with a coating solution of a solvent and the coating agent for at least 5 minutes. The coating agent has a concentration in the solvent greater than 1 wt. %. Excess coating solution is removed from the exterior surface of the silicone septum. The exterior surface is dried to remove the solvent, forming the surface coating.
