Hydroxypropyl Methyl Cellulose are non-ionic cellulose ether widely used in construction materials. Could be dissolved in hot or cold water and form a transparent solution with the particular visxosity.
Notmally, Hydroxypropyl Methyl Cellulose could be widely used in dry mortar fields, Tile adhensive, EIFS, Joint filler, self-leveling mortar. plaster, skim coat, paint and coatings, etc.To improve the adhension strength, water retention, anti-slipping and workability, etc. Hydroxypropyl Methyl Cellulose could provide a better stability in high temperature environment.
characteristic of HPMC
The product is soluble in water and organic solvents, exhibiting thickening, water binding, thermal gelation, surface activity, film formation, surface activity, enzyme resistance, pH-stability, non-ionic, and non-caloric characteristics.
3. What are the dissolution methods of hydroxypropyl methylcellulose (HPMC)?——Answer: Hot water dissolution method: Since HPMC does not dissolve in hot water, HPMC can be uniformly dispersed in hot water at the initial stage, and then quickly dissolve during cooling. Two typical methods are describe
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
