As a vital non‑ionic cellulose, Construction‑Grade HPMC (Hypromellose / Hydroxypropyl Methyl Cellulose) is specially engineered as functional additive for dry‑mix building chemical formulations. Derived from refined cotton raw material under strict production process, our HPMC powder delivers consistent viscosity batch after batch. It addresses frequent construction issues including fast water loss, mortar sagging, short open time and wall surface cracking. Widely adopted by dry‑mix mortar factories, building material manufacturers and construction project suppliers globally.
We supply multi‑viscosity grades ranging from 40000cps up to 200000cps (2% Brookfield solution). Custom viscosity specifications can be adjusted to match your unique mortar formula requirements.
Superior water‑locking performance: Slow down surface water evaporation, allow sufficient hydration reaction for cement and gypsum materials. Minimize early‑stage cracking and powder‑dropping risk of putty and plaster layers.
Anti‑sagging property for vertical work: Boost mortar cohesion, prevent slipping when applying on walls and ceilings, fit both hand trowel and mechanical spraying construction.
Optimized open time: Prolong working time of tile adhesive, giving more adjustment window for tile laying operation.
Enhanced workability: Make mortar smoother during spreading and trowelling, lower construction labor difficulty.
Excellent material compatibility: Mix perfectly with cement, gypsum, hydrated lime and other inorganic building raw materials without bad precipitation or segregation.
Good cold‑water dispersibility: Less lump formation during stirring, easy dissolution in mixing procedure.
Our building HPMC serves as indispensable raw material for multiple building chemical finished goods:
Interior & exterior wall skim coat and wall putty: Improve surface forming quality, reduce hollowing and crack defects.
Floor & wall tile adhesive, tile joint grout: Raise bonding strength, extend usable open‑time.
Gypsum‑based products: gypsum plaster, joint filler, gypsum self‑levelling compound, regulate setting behaviour.
Dry‑mix plastering mortar, cement rendering mortar for on‑site building projects.
External Thermal Insulation Composite System (ETICS) mortar for building thermal insulation works.
Cement‑based self‑levelling underlayment, avoid material bleeding and stratification.
