Excellent water retention performance of GinShiCel® cellulose ether effectively reduces the absorption of water by the cement-based hollow substrate, ensures sufficient hydration time for the gel material, and improves the bonding strength;On the one hand, the worker can be guaranteed to scratch the putty on the wall many times. The modified cellulose ether can significantly increase the water demand of the putty material. Even in a high temperature environment, it can maintain good water retention, which is suitable for construction in summer or hot areas; on the other hand, it can also increase the coating area of ​​the putty, making the recipe more economical.
