することが必要であった。DETAILED DESCRIPTION OF THE INVENTION Various two-component urethane adhesives, in which one component is mainly composed of an inanate compound and the other component is mainly composed of a polyol, are already commercially available. Due to poor adhesion, it has conventionally been necessary to apply a primer for adhesion of such materials.
一方二液ウレタン接着剤は、二液混合後徐徐に増粘し、
硬化時間を短かくすると可使時間が極端に短かくなり塗
布機のメンテナンス等作業性が悪くなり、二液混合波可
使時間を３０分程度にすると硬化に数時間かかシ作業性
が悪いという欠点があった。On the other hand, two-component urethane adhesives gradually thicken after mixing the two components,
If the curing time is shortened, the pot life will be extremely short and workability such as maintenance of the coating machine will be poor.If the pot life time of the two-component mixed wave is set to about 30 minutes, it will take several hours to cure and the workability will be poor. There was a drawback.
