HPMC powder for self-leveling compounds
,construction industry HPMC powder
,self-leveling HPMC powder
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose manufactured from refined cotton through a series of processing steps. It is widely used in self-leveling compounds, tile adhesives, cement mortars, gypsum-based products, and wall putties because of its excellent water retention, thickening ability, improved workability, and anti-segregation performance.
For self-leveling applications, specially developed low-viscosity HPMC grades offer excellent flowability while providing adequate water retention. This helps reduce bleeding, material segregation, and shrinkage cracking, contributing to a smoother and more uniform finished surface.

HPMC helps slow down rapid water loss during the hydration process, supporting more complete cement hydration and contributing to improved final mechanical strength.
Low-viscosity HPMC grades help maintain excellent fluidity while avoiding a significant increase in slurry viscosity.
The cellulose network structure helps reduce particle settlement and bleeding, resulting in a smoother and more homogeneous finished surface.
By controlling water evaporation, HPMC helps reduce plastic shrinkage and minimize the risk of crack formation.
