Construction‑Grade HPMC, also known as Hypromellose (Hydroxypropyl Methyl Cellulose), serves as a key functional raw material widely used in modern dry‑mix building manufacturing. Produced from high‑purity refined cotton via mature manufacturing workflow, our HPMC powder maintains steady performance across different production batches. It improves the overall working performance of cement‑based and gypsum‑based building materials, supporting both large‑scale mortar factory mass‑production and field construction projects.
We supply viscosity options covering 40000cps‑200000cps under 2% Brookfield aqueous solution test condition. We are able to adjust specifications to satisfy special formula requirements from different manufacturers.
Boost mortar cohesion performance: Greatly enhance the internal binding force of mortar mixes. Prevent slipping and dropping when applied to vertical walls and ceilings, compatible with hand trowel construction as well as mechanical spray plastering operation.
Efficient moisture locking capacity: Retain water inside mortar mixes effectively. Avoid overly fast surface drying under high‑temperature construction surroundings, guarantee sufficient hydration reaction for cement and gypsum materials, lower occurrence of peeling and surface flaw.
Optimize on‑site operability: Deliver smoother spreading and troweling experience for construction workers. Cut construction resistance and help acquire flat, fine wall finishing surface after curing.
Extend usable working window: Offer longer adjusting time for tile laying and surface finishing work, convenient for on‑site modification and layout adjustment.
Wide material compatibility: Mix harmoniously with cement, gypsum, hydrated lime and various common building raw materials. No abnormal agglomeration or layer separation during mixing process.
Good cold‑water dispersing feature: Easy to disperse and dissolve in normal‑temperature water, reduce lump formation during material mixing.
This building‑grade HPMC is widely utilized for multiple finished dry‑mix building products:
Interior & exterior wall putty, wall finishing compounds
Ceramic tile adhesive, tile joint filler and grout materials
Gypsum plaster, gypsum repair mortar and gypsum leveling products
Cement rendering mortar and masonry bonding mortar
External thermal insulation protective mortar for building outer wall
Cement‑based floor leveling mortar and decorative construction mortar
