HPMC is a type of non-ionic cellulose ether, white powder appearance, odorless and tasteless, soluble in water and most polar organic solvents. Its water solution has a surface activity, high transparency, stable performance. HPMC has a thermal gel properties, after heating, the product solution formed the gel precipitation, dissolving after cooling. Different specifications products have different gel temperature. Solubility changes with viscosity's difference. The lower viscosity, the higher solubility, different specifications HPMC have difference in properties, dissolving HPMC in water won't be affected by PH value.
HPMC For Construction
HPMC for construction is a non-ionic cellulose ether obtained by alkalization, etherification, neutralization and washing of cellulose.HPMC powder has good properties of thickening, dispersing, emulsifying and film-forming, and it is the first choice for the production of high-quality building material additives.
The use of hydroxypropyl methyl cellulose in construction
In construction, putty powder is used in very large quantities. About 90% of HPMC in construction is used as putty powder additives, and the rest is cement mortar and glue, used as thickening and water retention agents.
The amount of HPMC chemicals CAS9004-65-3 added to construction materials is very low, only 0.1%-1%, but it plays an irreplaceable role, which can significantly improve the water retention, fluidity and lubricity of construction materials. Building materials with added HPMC cellulose are easier to mix and use, improving the efficiency of construction workers, extending open time, improving bond strength, and forming a smooth and delicate surface coating.
- Construction HPMC powders are used in cementitious mortars and grouts to improve ease of use, adhesion and water retention.
- Hydroxypropyl methyl cellulose is also used in self-leveling compounds, tile adhesives and grouts to improve flow and workability.
-Construction HPMC is commonly used as a binder and thickener in coatings and paints.
- HPMC binders are also used in gypsum-based materials such as wallboard and ceiling tiles to improve workability and reduce water absorption.

HPMC It's a kind of chemical materials, white or slight off-white granular powder, ororless. HPMC is a natural polymer materials as a raw materials, through a series of chemical processing and prepared non-ionic cellulose.
What is HPMC for gypsum
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained from cellulose after alkalinization, etherification, neutralization and washing.
HPMC for gypsum has good thickening, dispersing, emulsifying and film-forming properties, and is the first choice for producing high quality building material additives.
Properties of HPMC for gypsum
To meet the needs of environmental protection, our product has the characteristics of high water retention, good dispersibility, good fineness, good processability and easy dissolution. It is widely used in building substrates, with good water retention and improved workability. It can also prolong the opening time and improve the anti-sagging property.

HPMC for wall putty is used to apply tiles on concrete or brick walls. It consists of cement, sand, limestone, our HPMC and various additives prepared for mixing with water prior to use. HPMC plays an important role in improving water retention, workability and sag resistance. In particular, HPMC for wall putty helps to improve adhesion strength and open time. As a functional decorative material widely used nowadays, tile has different shapes and sizes, unit weights and densities, and how to paste this durable material is a constant concern. the presence of HPMC for wall putty ensures to some extent the reliability of bonding works, and the appropriate cellulose ether ensures the smooth construction of different types of ceramic tiles on different bases The appropriate cellulose ether can ensure the smooth construction of different types of ceramic tiles on different foundations. We have a wide range of HPMC products available for various tile bonding applications to ensure the development of strength and achieve excellent bonding strength.
Wall putty is a waterproof white cement-based putty ideal for use on concrete/mortar walls (interior and exterior) and ceilings. It fills the fine pores of mortar/concrete walls and ceilings and proves to be the white, smooth and dry surface necessary for painting.
Thickening: Our HPMC products thicken putty powders to enhance their suspending ability, resistance to sagging, and to maintain a homogeneous solution.
Water Retention: Our product keeps the putty powder in a moist state, allowing the auxiliary calcium ash to react in the presence of water.
