Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.

HPMC WATER HOLDING ADDITIVE + FEATURES

1.Stability
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, wall plaster mortar, 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.

3. Dispersibility
In the production of synthetic resin, HPMC Hydroxypropyl MethylCellulose plays the role of protective colloidal agents and can effectively prevent polymeric particles from agglomerating.

4. Adhesion
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. 

5. Thickening Property
In interface agents, HPMC Hydroxypropyl MethylCellulose mainly functions as the thickening agent and can increase the the tensile strength and flexural strength.

6. Constructability
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, and prevent falling of tiles due to excessive water loss.
