Abstract

This invention relates to a method of treating an elastomeric seal for a pressurised dispenser device that dispenses a medicament in a carrier fluid, the method including the steps of: providing said elastomeric seal; and surface modifying the elastomeric seal by fluorinating the surface of same using a plasma which is formed using at least one fluorine containing precursor, wherein the fluorination converts hydrocarbon moieties on the surface of said seal into fluorocarbon moieties.
