CAS No.: 9004‑65‑3
Our construction‑grade HPMC is a non‑ionic water‑soluble multi‑functional additive tailored for diverse dry‑mix building mortar systems. Manufactured from high‑purity refined cotton linter via alkalization, chemical modification, washing, drying and fine grinding procedures, this hypromellose powder delivers steady viscosity performance, outstanding water‑holding capacity, reliable anti‑sag property, extended working time and rapid cold‑water dissolving performance. As an indispensable raw material in modern building chemical production, our HPMC offers stable batch‑to‑batch performance as a cost‑effective alternative to well‑known imported brands, supported by direct factory pricing.
Powerful Water Retention Performance
Locks moisture inside mortar mixtures and prevents fast water evaporation under high‑temperature and dry working conditions. Sufficient hydration of cement and gypsum is guaranteed, lifting final bonding strength. It effectively reduces common defects such as hollowing, cracking and surface powder‑off for wall putty, tile adhesive and gypsum‑based mortar.
Reliable Anti‑Sag and Anti‑Slip Property
Possesses excellent thickening and suspension capacity. It supports thick‑layer application without slipping or sagging, well‑suited for vertical wall plastering, heavy skim coat construction and large‑size ceramic tile installation.
Extended Working Time & Better Construction Workability
Significantly prolongs the usable operating period of mixed mortar. It brings smoother troweling and easier spreading for site workers, lowers construction resistance, improves working efficiency and cuts material waste.
Stable Viscosity & Reproducible Batch Performance
Available viscosity ranges cover 20000cps‑200000cps with tight production control. Low ash content and minimal insoluble particles avoid nozzle clogging during machine spray application. Every batch keeps stable performance for continuous factory production.
Fast Cold‑Water Solubility
Special surface‑treated powder disperses quickly in regular cold water without agglomeration or lump formation. Perfectly fits automatic batching lines for dry‑mix material manufacturers.
Broad Raw‑material Compatibility
Fits well with cement, gypsum, hydrated lime, quartz sand, redispersible polymer powder and other common mortar ingredients. No adverse chemical reactions occur within standard building formula systems.
