Where :R=-H , -CH3 , or -CH2CHOHCH3；X=degree of polymerization .
Hydroxypropyl methylcellulose(HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. They are an odorless, odorless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. It has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid. Hydroxypropyl methylcellulose, methyl cellulose can be used in construction materials, coatings industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemical and other industries.

1. Cement-based painting mortar
Hydroxypropyl methylcellulosecan 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.
The excellent water retention of Hydroxypropyl methylcellulose 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
Hydroxypropyl methylcellulose 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
THydroxypropyl methylcellulose 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
Hydroxypropyl methylcellulose can improve the homogeneity of the mortar,which permits an easier painting,higher working efficiency and resistance to sagging.
