Construction‑grade HPMC, also called Hypromellose (Hydroxypropyl Methylcellulose), is a functional dry‑mix mortar ingredient produced from premium refined cotton. This fine white‑to‑off‑white powder is purpose‑built for cement‑mixed and gypsum‑based construction formulas. It modifies multiple physical properties of mortar, delivering stable working performance for different construction scenarios.
Our HPMC supports viscosity from 100000‑200000 mPa·s (2% Brookfield), with custom viscosity options available to match diverse formula requirements. The 1% aqueous solution shows pH value between 5.0‑8.0. Rigorous production control keeps batch consistency, suitable for continuous large‑volume production of dry‑mix factories.
‑ Reduce water evaporation rate of mortar. It locks internal moisture inside mortar blends, slowing down quick water loss under hot, dry or windy site environments. Sufficient hydration of cement and gypsum can proceed normally, helping mortar gain ideal curing performance.
‑ Offer outstanding anti‑sag performance. It strengthens mortar internal network structure. When applied to vertical walls and overhead surfaces, mortar will not slide or drip. Compatible with manual trowel work as well as mechanical spray plastering workflows.
‑ Upgrade mortar workability. It reduces mixing resistance, makes smearing and spreading much easier. Construction crews can obtain even, smooth mortar surface with less labor input.
‑ Extend mortar open time. Provide sufficient operating interval for tile laying, surface trimming and partial repair work, effectively raising overall site construction efficiency.
‑ Excellent formula compatibility. Can blend homogeneously with cement, gypsum, hydrated lime and other common building raw materials. No lump generation or phase separation occurs under standard mixing conditions.
‑ Convenient cold‑water dispersion. Can be adopted in automatic batching workshops of dry‑mix plants, also fits simple manual mixing operations on construction sites.
Our HPMC acts as a vital functional additive for below dry‑mix building products:
Interior & exterior wall putty
Ceramic tile adhesive and tile grout
Gypsum plaster, gypsum levelling mortar and gypsum repair products
Masonry mortar and cement rendering mortar
External wall thermal insulation mortar and protective mortar
Machine spray plaster and other decorative dry‑mix building materials
