MULTILAYER BODY WHOSE SURFACE IS TREATED TO BE NONADHESIVE AND USE THEREOF

摘要

Disclosed is a multilayer body wherein sealing property intrinsic to a rubber is not deteriorated, and fixation of a rubber layer as well as fall-off of a solid lubricant from a nonadhesive treated layer hardly occur. In addition, wear and deterioration of the rubber layer due to bleeding of a binder, which is liquefied under high temperature conditions, also hardly occur in this multilayer body. Specifically disclosed is a multilayer body wherein a nonadhesive treated layer is arranged on a rubber layer. This multilayer body is characterized in that the nonadhesive treated layer is formed by applying a coating composition for nonadhesive treatment which contains a solid lubricant, a fluorine rubber, a vulcanizing agent and a liquid carrier. The multilayer body is also characterized in that the nonadhesive treated layer has a thickness of less than 5 µm.
