Product Overview
Construction‑grade HPMC is a high‑performance functional additive for dry‑mix mortars, manufactured from premium refined cotton raw material. It is supplied as fine white‑to‑off‑white powder, specially developed for cement‑mixed and gypsum‑based building formulations.
It improves multiple physical performances of mortar and maintains stable workability under diverse on‑site construction conditions.
Our HPMC series covers viscosity grades from 100 000‑200 000 mPa·s (2% Brookfield test). Custom viscosity specifications are available to satisfy diverse formulation requirements. The pH value of its 1% aqueous solution ranges 5.0‑8.0. Strict production management ensures reliable batch‑to‑batch consistency, well adapted for large‑scale continuous production of dry‑mix material factories.
Functional Advantages
‑ Reduce mortar water evaporation rate. It locks internal moisture inside mortar mixes and slows excessive water loss under hot, dry or windy construction conditions. It guarantees full, normal hydration of cement and gypsum to achieve ideal mortar curing results.
‑ Deliver remarkable anti‑sag property. It strengthens the internal network structure of mortar. Mortar will not slip or drip when applied to vertical walls and overhead substrates. It works well for both hand trowel application and mechanical spray‑plastering processes.
‑ Optimize mortar workability. It reduces mixing resistance for easier smearing and spreading. Operators can obtain uniform, smooth mortar finishes with less labor effort.
‑ Extend mortar open time. It offers sufficient operating time for tile laying, surface finishing and partial repair work, effectively boosting overall construction efficiency.
‑ Great formula compatibility. It mixes homogeneously with cement, gypsum, hydrated lime and other conventional building raw materials. No caking or phase separation happens under standard mixing conditions.
‑ Fine cold‑water dispersibility. Suitable for automatic batching systems in dry‑mix production plants, as well as simple manual mixing on construction sites.
Main Application Areas
Our HPMC acts as an essential functional additive for the following dry‑mix building products:
‑ Interior and exterior wall putty ‑ Ceramic tile adhesives and tile grouts
‑ Gypsum plaster, gypsum levelling mortar and gypsum repair compounds
‑ Masonry mortar and cement rendering mortar
‑ External wall thermal‑insulation mortar & protective mortar
‑ Machine‑sprayed plaster and other decorative dry‑mix building materials

Q1: What is the main function of this HPMC in dry‑mix mortar? A: It mainly provides water retention, anti‑sag property and improves workability. It slows water evaporation, ensures full hydration of cement and gypsum, prevents mortar slipping on vertical walls, and makes construction spreading easier.
Q2: What is the recommended dosage for building mortar? A: Typical addition dosage ranges from 0.1%‑0.5% based on total weight of dry‑mix materials. Exact dosage depends on your formula, mortar type and local climate conditions. Small‑scale formula testing before mass production is suggested.
Q3: What viscosity grade should I choose? A: Lower viscosity grades suit machine spray plaster; higher viscosity grades are for wall putty, tile adhesive and anti‑sag demanding formulas. We support custom viscosity from 40000‑200000 cps. You may tell us your end‑product for grade suggestion.
Q4: Can it mix well with cement, gypsum and lime? A: Yes. It shows good compatibility with common building raw materials. No caking or phase separation will occur under standard mixing procedures.
Q5: Does it dissolve in cold water? A: It features good cold‑water dispersibility. It can be used for factory automatic batching lines as well as simple manual mixing at construction sites.
Q6: What is your storage requirement? A: Store in cool and dry warehouse, keep away from direct sunlight and moisture. Seal bags after partial use to avoid moisture absorption.
Q7: What is your delivery lead time? A: Normally 7‑15 working days upon receiving deposit. Lead time depends on order quantity and stock status.
