Chemical HPMC for Building material

As being dispersant, during polymerization of PVC dispersion polymer system, hydroxypropyl methyl cellulose can form dispersion system together with several PVA of different alcoholysis degrees to disperse monomer to fine particles. It may effectively improve suspending dispersion performance,change the particle configuration and enhance the absorbency of plasticizer.

★ Water retention
YICHENG products prevent extreme absorption of moisture by substrates. Moisture should be kept in the mortar until the plaster is cured. Water retention ability of cellulose ether varies directly with viscosity of mortar solution, which means that the higher viscosity of solution, the better water retention. As long as moisture content goes up, the water retention will decrease. This is caused by dilute cellulose solution along with water content increasing, therefore, it results with viscosity dropping.
