Construction Grade HPMC (Hypromellose, Hydroxypropyl Methylcellulose) is a vital cellulose‑based functional additive tailor‑made for dry‑mix building materials. Manufactured from premium refined cotton raw material, this white to off‑white fine powder delivers stable batch‑to‑batch performance for mortar production. Characterized by cold‑water solubility and adjustable gel temperature, it effectively optimizes multiple construction‑related properties of cement‑based and gypsum‑based mixes.
We supply wide viscosity range from 40000cps‑200000cps under 2% Brookfield aqueous solution test. Custom grades can be provided to match your unique formula requirements for different end‑use products.
Outstanding water retention capability. It locks moisture inside mortar mixes, prevents too‑fast water loss under high‑temperature or windy construction environments. Sufficient hydration of cement and gypsum can be realized, lowering risks of cracking, peeling and hollowing on wall surfaces.
Excellent anti‑sagging property. Strengthen internal cohesion of mortar, avoid slipping and dropping when applied on vertical walls and ceilings. Fully compatible for manual trowel work as well as mechanical machine spray plastering.
Greatly improve mortar workability. Reduce construction resistance during spreading and trowelling, bring smoother operating experience for workers, help achieve fine and uniform finished surface.
Reasonably extend open time. Offer extra adjusting period for tile installation and surface finishing work, convenient for on‑site trimming and layout adjustment.
Good material compatibility. Homogeneously blend with cement, gypsum, hydrated lime and other common building raw materials. No clumping or phase separation happens during mixing process.
Easy dispersion in cold water. Simplify feeding operation both in mortar factory production line and field on‑site mixing.
Our construction‑grade HPMC is widely adopted for manufacturing kinds of dry‑mix building products:
Interior & exterior wall putty and wall finishing compounds
Ceramic tile adhesive, tile grout and joint filler
Gypsum plaster, gypsum repair mortar and gypsum levelling products
Masonry mortar, cement rendering mortar
External wall thermal insulation protective mortar
Machine‑sprayed plaster and decorative construction mortar
