HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose used in building materials, which can be dissolved in hot or cold water to form a transparent solution with a specific viscosity.
Normally HPMC is widely used in dry-mixed mortar industry, ceramic tile binder, external insulation system, self-leveling mortar, plastering, putty, paint and so on, it can improve construction performance, water retention performance, bond strength and sagging resistance.
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
