If the amount of phenol added is large, the alkali resistance will be clearly inferior, and when it is put to practical use as a fixing agent for bolt fixing, the strong alkalinity of concrete will greatly reduce the fixing performance.

Contains 7 to 1.5 equivalents of xylene diamine, so it has high adhesion performance even when cured at low temperatures, and has excellent durability for bolt fixing without significantly decreasing the adhesion strength against alkalinity. agent can be obtained. Furthermore, a fixing agent containing a predetermined amount of phenol has even better fixing strength and faster curing speed. Therefore,
Even during construction in winter, it will not cause curing failure or reduce workability.
