ていた。However, in the case of reactive adhesives such as epoxy-based adhesives, it is difficult to select a filler, which causes gelation and heart cake during storage of the adhesive. Therefore, very short fibers of asbestos or its powder (hereinafter simply referred to as asbestos) are often used as fillers, and adhesives with good storage stability can be obtained. However, asbestos is designated as a harmful mineral dust under the Industrial Safety and Health Act, and it poses a serious problem in the working environment during manufacturing, leading to the development of solvent-based adhesives that use other harmless fillers instead of asbestos. It was strongly desired.
