Construction Grade HPMC, also known as Hypromellose (Hydroxypropyl Methylcellulose), is a multi‑functional building additive manufactured from premium refined cotton. This white to off‑white fine powder is widely applied in cement‑based and gypsum‑based dry‑mix materials, bringing comprehensive performance improvement for various construction formulas.
Our HPMC features cold‑water solubility and adjustable gel‑point from 60℃‑90℃. Strict batch‑to‑batch control guarantees stable quality for large‑scale factory production. Available viscosity range covers 100000‑200000cps (2% Brookfield), customized viscosity grades are acceptable to match diverse project requirements.
‑ Excellent water‑locking performance. It slows down water evaporation under high‑temperature, dry or windy working conditions. Sufficient hydration reaction of cement and gypsum can be achieved, effectively lower risks of wall cracking, hollowing and peeling after curing.
‑ Good anti‑slump property. Enhance inner cohesion of mortar mixtures. Mortar will not sag or fall off when applied on vertical walls and ceilings. It works well for manual trowel operation as well as automatic machine spray plastering.
‑ Upgrade mortar workability. Reduce mixing and spreading resistance during construction. Operators can finish surface smoothing more effortlessly and obtain uniform, delicate wall finishing.
‑ Prolong practical working time. Offer sufficient adjustment period for tile laying, surface trimming and on‑site modification, greatly improving overall construction efficiency.
‑ Wide formula compatibility. Can blend evenly with cement, gypsum, hydrated lime and other common building raw materials. No unwanted agglomeration or layering occurs in mixing process.
‑ Simple cold‑water dispersion. Convenient for automatic batching in mortar plants and manual mixing at construction sites, simplify your whole production workflow.
Our construction HPMC serves as key raw material for multiple dry‑mix building products:
Interior and exterior wall putty
Ceramic tile adhesive, tile grout and joint filler
Gypsum plaster, gypsum repair and levelling mortar
Masonry mortar, cement rendering plaster
External wall thermal insulation mortar and protective mortar
Machine spray plaster and other decorative construction mortars
