Our construction grade HPMC is a non‑ionic water‑soluble cellulose specially developed as multi‑functional additive for all kinds of dry‑mix building mortars. Produced from refined cotton linter through complete alkalization, washing, drying and milling process, this hypromellose powder features stable viscosity, ultra‑high water retention, excellent anti‑sag performance, long open time and fast cold‑water dissolution. Widely recognized as core raw material for modern construction chemical manufacturing, our HPMC can perfectly replace imported brands including Walocel, Tylose and Methocel with consistent batch‑to‑batch quality and competitive factory‑direct price.
Superior Water Retention Capacity
Effectively lock free water inside mortar system, prevent rapid water loss under high temperature and dry air environment. Fully guarantee sufficient hydration reaction of cement and gypsum, greatly improve final bonding strength, avoid hollowing, cracking and powder falling of wall putty, tile adhesive and plaster.
Outstanding Anti‑Sag & Slip Resistance
Great thickening and suspending property enables thick‑layer construction without sagging or tile slipping. Ideal for vertical wall plaster, thick skim coat and large‑size ceramic tile bonding.
Extended Open Time & Improved Workability
Remarkably prolong the operable time of mixed mortar. Workers enjoy smoother troweling, easier spreading and less drag during construction, significantly boost construction efficiency and reduce material waste.
Stable Viscosity & Consistent Batch Quality
Strict viscosity control range from 20,000cps to 200,000cps, no big fluctuation between production batches. Low ash content, low insoluble substance, no impurities to block spray equipment for machine rendering.
Fast Cold Water Dissolution
Special surface treatment technology supports quick dissolution in normal cold water without agglomeration, no lumps during mixing, convenient for automatic batching production line of dry mix factory.
Wide Compatibility with All Building Raw Materials
Good compatibility with cement, gypsum, lime, quartz sand, redispersible polymer powder (RDP), other common mortar additives, no adverse chemical reaction in formula system.
