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.
