Construction‑grade Hydroxypropyl Methylcellulose, also widely known as HPMC or Hypromellose, is a high‑performance cellulose specially engineered for dry‑mix building material formulations. Produced from premium refined cotton through etherification reaction, this white‑to‑off‑white fine powder serves as a multi‑functional building additive for cement‑based and gypsum‑based construction systems.
Featuring cold‑water dispersibility and adjustable gel‑point ranging from 60℃‑90℃, our HPMC delivers reliable batch consistency for large‑scale mortar plant production. Available viscosity range covers 40000‑200000cps tested by 2% Brookfield aqueous solution. Custom‑tailored grades are supported to satisfy diverse formula scenarios.
Superior water retention capacity. It locks internal moisture within mortar mixes, prevents rapid moisture evaporation under high‑temperature, dry or windy construction environments. Sufficient hydration of cement and gypsum components can be guaranteed, effectively reducing wall cracking, hollowing and peeling risks.
Remarkable anti‑sagging and anti‑slump performance. Reinforces internal structural cohesion of mortar mixtures. Mortar will not slide or fall off when applied on vertical walls and overhead surfaces. Perfectly fit for hand trowel operation as well as automatic mechanical spray plastering.
Optimize mortar spreadability and workability. Lower construction resistance during mixing and application. Workers can spread mortar more effortlessly, achieving smooth, uniform and delicate wall finishing surface.
Prolong practical open time. Creates sufficient adjustment window for tile laying, surface smoothing and on‑site trimming operations, improving construction efficiency on site.
Excellent formulation compatibility. Can be uniformly blended with cement, gypsum, hydrated lime and other common building raw materials. No undesirable agglomeration or phase separation occurs during mixing procedures.
Convenient cold‑water dispersion property. Easy feeding for both automated batching lines in mortar factories and manual mixing at construction sites, simplifying overall production workflows.
Our construction‑grade cellulose HPMC is extensively applied in manufacturing various dry‑mix building products:
Interior and exterior wall putty, decorative wall finishing mortars
Ceramic tile adhesive, tile grout and joint filling compounds
Gypsum plaster, gypsum levelling mortar and gypsum repair products
Masonry mortar, cement rendering and plastering mortar
External wall thermal insulation mortar and protective coating mortar
Machine spray plaster, special decorative dry‑mix building materials
