Cellulose ether has a wide range of uses in the building materials industry.Can be used as retarder, water retention agent, thickener and binder.
The most important roles of cellulose ether (especially HPMC and HEMC) in cement-based adhesives are water retention and thickening.In addition, due to its interaction with the cement system, it also plays an auxiliary role in entraining air, delayed coagulation and improving tensile bond strength.

Characteristics of ceramic tile adhesive
1. improve the plasticity and water retention of pressed ceramic tile mortar, improve the adhesive force of ceramic tiles, and prevent pulverization.
2. it is easy to mix, operate and spread without sticking the knife.
3. good anti hanging effect; Good initial adhesion.
4. long opening time, good wettability and long adjustable time.
