HPMC Hydroxypropyl MethylCellulose has thermal gelation properties, so after heating the aqueous solution will precipitate and form gels, and dissolve again after cooling. Products of different specifications have different gelling temperatures. Its solubility varies with the viscosity, and the lower the viscosity is, the greater the solubility will be. There are some differences in the properties of Hydroxypropyl MethylCellulose of different specifications. The dissolution of HPMC / MHPC Hydroxypropyl MethylCellulose in water is not affected by the pH value.

In the water-based paints, HPMC Hydroxypropyl Methyl Cellulose has excellent storage stability, maintains uniform viscosity, makes pigments uniformly dispersed, and basically won’t be affected by the pH value.
2. Water-holding Property
In wall putty/ wall skim coat, the main roles of celluloses are water retention, adhesion, lubrication and so on. HPMC Hydroxypropyl Methyl Cellulose has high water-holding performance, surface opticity and improves uniformity. This helps to avoid crusting and off-powder phenomena, improve resistance to shrinkage, cracking and vertical flow, and to improve the work efficiency since the painting job is comfortable and saves effort.
In the production of synthetic resin, HPMC Hydroxypropyl Methy lCellulose plays the role of protective colloidal agents and can effectively prevent polymeric particles from agglomerating.
4. Adhesion in tile glue / bond
In such materials as the adhesive mortar and surface mortar in the thermal mortar system, celluloses mainly plays a role of bonding, water retention and increasing strength. It also helps to improve construction, water-retaining property and resistance to hanging.
In the bonding of tiles, tile adhesives , HPMC can function as water-retaining agent and adhesives, and can greatly improve construction performance of adhesives, allow longer opening hours and greater cohesion
