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.
