摘要:
Die Erfindung beschreibt ein Verfahren zum Beschichten eines Substrats mit wenigstens zwei Schichten, gekennzeichnet durch die folgenden Schritte: a) Aufbringen einer ersten Schicht, enthaltend eine erste anorganische Komponente, auf ein Substrat oder auf eine von wenigstens einer auf einem Substrat aufgebrachten Schicht; b) Behandeln der ersten Schicht mit einem Plasma; c) Aufbringen einer zweiten Schicht, enthaltend eine zweite anorganische Komponente, auf die erste, mit Plasma gemäß b) behandelte Schicht.
摘要:
The present invention relates to a continuous roll-to-roll process for improving the water tolerance of bio-based polymers, in particular cellulose nanofibrils (CNF) films. Furthermore, the invention provides a method, which combines surface modification/functionalization for improving water stability and wet strength, UV/Ozone treatment, corona treatment or plasma activation for purifying and activating the surface and thus increasing the reaction efficiency, and further hydrophobization of the surface of CNF film.
摘要:
A method of handling of a liquid drug formulation, comprising a step of providing a first primary container and coating the inner surface of the first primary container to be exposed to the formulation with a barrier layer to prevent or at least limiting any escape of material from the inner surface of the first primary container, a step of providing a second primary container and coating the inner surface of the second primary container to be exposed to the formulation with a barrier layer to prevent or at least limit any escape of material from the inner surface of the second primary container, wherein the barrier layer coating the inner surface of the second primary container has the same material composition as the barrier layer coating the inner surface of the first primary container, and a step of transition from handling the formulation filled in the first primary container at a first handling phase to handling the formulation filled in the second primary container at a subsequent handling phase so as the formulation exhibits with the second primary container the same kind of interaction as with the first primary container.

The invention relates to a lubricant coating (5) for a medical injection device (1), comprising successively: - a bottom layer (50) in contact with the medical device surface (21) of the container to be lubricated, comprising a mixture of cross-linked and non-cross-linked poly-(dimethylsiloxane), - an intermediate layer (51) consisting essentially of oxidized poly-(dimethylsiloxane) and having a thickness comprised between 10 and 30 nm and, - a top layer (52) consisting essentially of non-cross-linked poly-(dimethylsiloxane) and having a thickness of at most 2 nm. The invention also relates to a medical injection device comprising such a lubricant coating, and a manufacturing process for said coating.
摘要:
The invention relates to the application of a coating to a substrate in which the coating includes a polymer material and the coating is selectively fluorinated and/or cured to improve the liquid repellance of the same. The invention also provides for the selective fluorination and/or curing of selected areas of the coating thus, when completed, providing a coating which has regions of improved liquid repellance with respect to the remaining regions and which remaining regions may be utilised as liquid collection areas.
