摘要： The present invention relates to a coating system, in particular to a coating system for articles where plastic materials slide against flexible rubber materials. The coating system is a silicone oil based coating having a viscosity of at least 200,000 centistokes, i.e. a high viscosity coating. The coating comprises in a preferred embodiment a silicone oil based block or graft copolymer, or segmented copolymer. Further the invention relates to a process of producing a component of an article coated as described above, comprising adding the coating material to the component material prior to molding and subsequently molding the component from the mixture, or molding the component from the component material and subsequently applying the coating material to the at least one surface of the component, as well as an article coated with a silicone oil based coating as defined above. Such an article is preferably a medical article, such as a container or an injection cylinder and a stopper. The coatings according to the present invention are especially suited to use for permanently coating internal surfaces of containers equipped with stoppers for storage and administration of liquid protein preparations. The coatings providing low friction between the two components, such as a container wall and a rubber stopper, result in high-precision dosing. The described coatings are particularly useful for coating containers for storage and administration of liquid protein solutions, such as insulin formulations.
摘要翻译：本发明涉及一种涂覆系统，特别涉及一种用于制品的涂层系统，其中塑料材料滑动抵靠柔性橡胶材料。该涂层系统是一种硅油基涂层，其粘度至少为20万厘沲，即高粘度涂层。该涂层在优选的实施方案中包括基于硅油的嵌段或接枝共聚物或分段的共聚物。此外，本发明涉及一种制造如上所述涂覆的制品的组分的方法，包括在模制之前将涂料添加到组分材料中，随后从混合物中模制组分，或者将组分从组分材料中模制，随后将涂层材料施加到部件的至少一个表面上，以及涂覆有如上所述的硅油基涂层的制品。这样的制品优选为医疗用品，例如容器，注射筒和塞子。根据本发明的涂层特别适用于永久地涂覆装有用于储存和施用液体蛋白制剂的塞子的容器的内表面。在两个部件之间提供低摩擦的涂层，例如容器壁和橡胶塞，导致高精度计量。所描述的涂层对于包衣容器特别有用，用于储存和施用液体蛋白质溶液，例如胰岛素制剂。
