摘要: An article is described including an surface and a coating set comprising tie or layer of SiO x C y Si(NH) applied to the surface, barrier , pH protective . The respective coatings layers can be by chemical vapor deposition polysiloxane polysilazane precursor in presence oxygen. Examples such are prefilled thermoplastic syringe pharmaceutical vial with coated interior portion containing preparation other fluid 4 8, alternatively 5 9. prevents oxygen from penetrating into vial, together protect contents vial.
