Abstract
A medicinal inhalation device having applied to a surface thereof a composition comprising a multifunctional polyfluoropolyether silane.
Claims14
A method of making a medicinal inhalation device or a component of a medicinal inhalation device comprising a step of:
- applying to at least a portion of a surface of the device or the component, respectively, a composition comprising a multifunctional polyfluoropolyether silane, wherein the polyfluoropolyether segment of the polyfluoropolyether silane is not linked to the functional silane groups via a functionality that includes nitrogen-silicon bond or a sulfur-silicon bond.
A medicinal inhalation device or a component of a medicinal inhalation device comprising a polyfluoropolyether-containing coating bonded to at least a portion of a surface of the device or the component, respectively, said polyfluorpolyether-containing coating comprising a plurality of cross-linked, multifunctional polyfluoropolyether-silane entities and said polyfluorpolyether-containing coating sharing at least one covalent bond with said surface, wherein the polyfluoropolyether segment of the polyfluoropolyether silane entities is not linked to the functional silane groups via a functionality that includes nitrogen-silicon bond or a sulfur-silicon bond.
