Application
MC and HPMC are widely used as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids, etc in construction materials, paints, paper making industry, printing, synthetic resins, ceramics, textiles, agriculture, etc.
Construction
1.Cement-based painting mortar
●The product can improve the homogeneity of the mortar, which permits an easier painting of the mortar. Thus the working efficiency is improved and the resistance to sagging is enhanced.
2.Putty
●The excellent water retention prolongs the workable time of putty, improves working efficiency, avoids occurrence of crusting phenomena and imparts high mechanical strength to putty during coagulating period.
3.Heat-preservation mortar system’s binding mortar and coating mortar
●The product can improve the homogeneity of the mortar, which permits an easier painting of the mortar. Thus the working efficiency is improved and the resistance to sagging is enhanced.
4.Interface treatment binder
●The product improves the surface coating, enhances the adhesiveness and increases the binding strength of mortar.
●The excellent permeability improves the homogeneity of the interface.
●The high water retention rate prolongs the open time and improves the tile-pasting efficiency.
5.Gypsum-based mortar and gypsum products
●The product can improve the homogeneity of the mortar, which permits an easier painting, higher working efficiency and resistance to sagging.

Painting industry
In water-based paints, the product is of good shelf stability to keep homogeneous viscosity and the even dispersion of pigments. Meanwhile, it is nearly independent upon Ph value
Synthetic resins:
During the manufacturing of synthetic resins, such as PVC, polyvinylidene chloride, etc, suspension polymerization is most frequently used, where it must be stable hydrophobic monomer
3.Ceramics
As a kind of binder for the molded refinery ceramic products, the relatively-high concentration solution of the product can be adsorbed on the surface of the ceramic grains, which can minimize
