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