Hydroxypropyl methyl cellulose is propylene glycol ether of methyl cellulose, hydroxypropyl and methyl combine with anhydrous glucose ring by ether bond.It is white or pale white cellulose powder or particles. The characteristics of cold water dissolution and hot water insoluble are similar with methyl cellulose. Solubility in organic solvents is superior than water soluble, can be dissolved in anhydrous methanol and ethanol solution, also soluble in chlorinated hydrocarbons and ketones in organic solvents.
Soluble in water, its water solution has a surface activity, the formation of the film after drying, heated and cooled, in turn, from the reversible conversion of sol to gel.

1.Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2.Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3.Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4.Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
1. Thickener, stabilizer, emulsifier, emulsifier, suspending agent.
2. It is used as a synthetic resin dispersing agent, and the coating agent,also used as a thickener.
3. This product is used as a thickener, dispersant, binder, emulsifier and stabilizer in the textile industry. It is also widely used in synthetic resin, petrochemical, ceramics, paper, leather, medicine, food, cosmetics and other industries.
4. Used in synthetic resin, petroleum chemical industry, ceramics, paper, leather, textile, medicine, food, cosmetics and other daily chemicals and as dispersing agent, thickening agent, binders, excipients, capsules, oil resistant coating and packing etc.
