Construction Grade HPMC, also known as Hypromellose (Hydroxypropyl Methylcellulose), is a high‑performance building additive manufactured from premium refined cotton raw material. This fine white‑to‑off‑white powder is specially formulated for various cement‑containing and gypsum‑based dry‑mix systems. It optimizes multiple practical properties of mortar and brings stable performance support for on‑site building operations.
Our HPMC features good cold‑water solubility, with pH value ranging 5‑8 for 1% aqueous solution. Strict production control keeps batch performance steady for continuous factory output. Viscosity covers 40000‑200000 mPa·s (2% Brookfield), and customized viscosity grades are available to satisfy different dry‑mix formula requirements.
‑ Excellent moisture holding capacity. It retains internal moisture inside mortar mixes, slowing water loss under high‑temperature, dry or windy construction surroundings. Sufficient hydration of cement and gypsum can be achieved, effectively lowering mortar shrinkage risk.
‑ Promote bonding strength of mortar. Enhance internal cohesion of mortar mass. When applied on vertical walls and overhead surfaces, mortar stays well without sagging or sliding off. It fits both hand‑applied work and mechanical spray plastering processes.
‑ Improve mortar workability. Reduce mixing resistance and make smoothing operation easier. Workers can obtain even, neat surface finishes with less effort during construction.
‑ Extend operable working period. Reserve enough adjustment time for tile laying, surface trimming and partial repair work, lifting overall construction efficiency.
‑ Wide formula compatibility. Can mix uniformly with cement, gypsum, slaked lime and other common building raw materials. No unwanted lumping or material separation occurs within normal mixing procedures.
‑ Easy dispersion in cold water. Suitable for automatic batching lines in dry‑mix mortar factories as well as simple manual mixing on construction sites.
