Construction Grade HPMC, also known as Hypromellose (Hydroxypropyl Methylcellulose), is a multi‑purpose building additive derived from high‑grade refined cotton. This white‑to‑off‑white fine powder is specially developed for cement and gypsum‑based dry‑mix formulations. It brings multiple performance upgrades to mortar systems and addresses many common issues during building construction.
Our HPMC features favorable cold‑water dissolving performance, with thermal gelation temperature ranging from 60℃‑90℃. Strict batch‑by‑batch quality control keeps performance consistent for large‑scale factory output. Viscosity ranges from 100000‑200000cps under 2% Brookfield test condition, and customized viscosity grades are available to satisfy diverse production requirements.
‑ Excellent moisture retention capability. It locks moisture within mortar blends and prevents fast water loss under hot, dry or windy construction surroundings. Sufficient hydration of cement and gypsum can be realized, helping to obtain stable curing results.
‑ Reinforce mortar internal bonding force. Effectively resist sagging and slipping when mortar is applied on vertical walls and overhead surfaces. Compatible with hand trowel work as well as mechanical spray plastering operations.
‑ Improve the spread property of mortar. Lower mixing and smearing resistance, allowing operators to achieve flat, uniform and neat surface finishing effect.
‑ Extend available working window. Provide adequate adjustment time for tile laying, surface smoothing and on‑site trimming, raising overall construction working efficiency.
‑ Good compatibility with various raw materials. Can be evenly blended with cement, gypsum, slaked lime and other common building ingredients without undesirable lump formation or liquid‑solid separation.
‑ Convenient cold‑water dispersion characteristic. Suitable for automated batching lines in mortar plants as well as manual mixing on construction sites, simplifying your whole production workflow.
Our HPMC additive serves as an essential raw material for a wide range of dry‑mix building products:
Interior and exterior wall putty
Ceramic tile adhesive, tile grout and gap filling compounds
Gypsum plaster, gypsum levelling mortar and gypsum repair products
Masonry mortar and cement rendering coats
External wall thermal insulation mortar and protective mortar
Machine spray plaster and special decorative dry‑mix building materials
