化物の硬度が低くなり充分な硬度が得られない。The amount of the polyol type xylene formaldehyde resin in the component (A) is in the range of 10 to 90 equivalent%, preferably 50 to 80 equivalent%. The amount of the polyol type xylene formaldehyde resin is 90 in the component (A).
When the amount exceeds the equivalent%, the hardness of the cured product increases, but the flexibility decreases, and the pot life decreases. On the other hand, if it is less than 10 equivalent%, the hardness of the cured product will be low and sufficient hardness cannot be obtained.
