  • Publication number: 20200270025
    Abstract: A method for providing a passivation layer or pH protective coating on a substrate surface by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising polymerizing gases. The lubricity, passivation, pH protective, hydrophobicity, and/or barrier properties of the passivation layer or pH protective coating are set by setting the ratio of the O2 to the organosilicon precursor in the precursor feed, and/or by setting the electric power used for generating the plasma. In particular, a passivation layer or pH protective coating made by the method is provided. Pharmaceutical packages coated by the method and the use of such packages protecting composition contained in the vessel against mechanical and/or chemical effects of the surface of the package without a passivation layer or pH protective coating material are also provided.

  • Patent number: 9952147
    Abstract: The invention is directed to a non-destructive method of detecting whether a coating or deposit (30, 34) of (a) SiOxCy or SiNxCy and/or (b) of SiOx is present on or near a surface of an article (12), such as a disposable thermoplastic medical article. The method includes impinging infrared light (216) having a wave number in at least a portion of a desired range onto at least a first surface being examined for the presence of the one or more coatings or deposits. At least a portion (224) of the infrared light impinged on the first surface is collected (at 222) and the response output, which may include for example the maximum intensity and/or peak area of the collected infrared light at an infrared spectroscopy peak, is used to indicate the presence of the one or more coatings or deposits.

  • Patent number: 9903782
    Abstract: An apparatus and methods for testing the integrity of a barrier coating on a vessel. An off gas test fixture includes a face seal positioned about an opening of the vessel. A side seal is positioned about a portion of the vessel's wall and separated from the face seal by a space. Additionally, a cover may be secured to the fixture that encompasses an interface portion of the fixture and the vessel. Before and/or during testing, gas in the space between the side and face seals may be evacuated, as well as gas present in an interior area of the vessel. The vessel may be exposed to test gas(es) that is soluble by the plastic material of the vessel before and/or after being secured to the fixture. During testing, test gas(es) desorbed by the vessel may be evacuated, with the molecular flow being measured using a mass extraction unit.

  • Patent number: 9863042
    Abstract: A method for coating a substrate surface such as a syringe part by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising an organosilicon precursor and optionally an oxidizing gas by providing plasma-forming energy adjacent to the substrate, thus forming a coating on the substrate surface by plasma enhanced chemical vapor deposition (PECVD). The plasma-forming energy is applied in a first phase as a first pulse at a first energy level followed by further treatment in a second phase at a second energy level lower than the first energy level. The lubricity, hydrophobicity and/or barrier properties of the coating are set by setting the ratio of the O2 to the organosilicon precursor in the gaseous reactant, and/or by setting the electric power used for generating the plasma.

  • Patent number: 9664626
    Abstract: A reflectometry method and other methods for detecting discontinuities in a chemical vapor deposition (CVD) coating are disclosed. The method includes several steps. A thermoplastic vessel wall (710) is provided having an outside surface, an inside surface, and a CVD coating on at least one of the inside and outside surfaces. The vessel wall and the CVD coating have different indices of refraction. Electromagnetic energy (718) is impinged on multiple positions of the CVD coating under conditions effective to cause energy to reflect from the multiple positions of the CVD coating. The reflected energy is analyzed to determine whether the reflected energy includes at least one artifact of a discontinuity in the CVD coating.

  • Patent number: 9458536
    Abstract: A method is disclosed in which a vapor-deposited coating or layer is directly or indirectly applied to at least a portion of the internal wall of the barrel of a capped pre-assembly comprising a barrel, optionally a dispensing portion, and a cap. The cap is secured to the barrel and at least substantially isolates the distal opening of the dispensing portion from pressure conditions outside the cap. A vapor-deposited coating or layer is applied directly or indirectly to at least a portion of the internal wall of the barrel while the pre-assembly is capped. The coating or layer is applied under conditions effective to maintain communication from the barrel lumen to the exterior via the front opening, optionally further via the dispensing portion lumen if present, at the end of the applying step. The capped pre-assembly can be pressure tested easily and rapidly, for example with a test duration between 1 and 60 seconds, to determine whether it has container closure integrity.
