This construction-grade Hydroxypropyl Methyl Cellulose is industrial white odorless fine powder raw material exclusively developed for all cement and gypsum dry-mix construction formulas, with exclusive CAS registry number 9004‑65‑3. All production batches follow unified factory testing standards covered in our specification document, and each lot is accompanied by a complete COA laboratory test certificate, standard MSDS safety manual and full technical parameter sheet to satisfy overseas import customs clearance and factory formula verification demands. Adopting refined cotton as core production feedstock, the product features tightly controlled substitution degree including Methyl Content 19%-24%, delivering consistent batch stability without large index fluctuation, favored by global dry mortar factories and construction chemical distributors for long-term bulk cooperation.
Appearance: Uniform white or off-white free-flow fine powder, odorless, no foreign impurities
Solubility Characteristic: Rapidly dissolved in cold water, completely insoluble under high temperature environment, free of fish-eye agglomeration during mixing operation
PH Value Range: 4.0-8.0 mild neutral property, no corrosion to cement, gypsum and base wall substrates
Loss On Drying: Strictly controlled below 5.0% to avoid excessive moisture affecting mortar stability
Ignition Residue (Ash): Low ash index, will not form hollowing or cracking after mortar curing
Bulk Density: 0.3-0.5 g/cm³, good flowability for automatic dry-mix production line mixing
Thermal Decomposition Temperature: 190-200℃, stable performance under normal construction temperature
Heavy Metal & Arsenic Content: All heavy metal and arsenic indicators meet building chemical safety thresholds, recorded clearly on batch COA reports
Viscosity Options: Multiple adjustable viscosity grades ranging from medium to high for matching different construction formulas
Standard Package: 25kg kraft bag lined with PE moisture-proof inner film, dustproof and damp-proof for long-distance sea transport
Powerful Moisture Locking Capacity
Can effectively lock internal moisture of mortar layers, slow down water evaporation under high temperature, strong wind and outdoor construction conditions, eliminate wall putty peeling, crack and hollow defects, greatly extend the operable construction period for workers.
Outstanding Anti-Slip & Bonding Performance
Effectively stop heavy ceramic, marble slabs sliding on vertical wall surfaces, significantly upgrade adhesive force between mortar and concrete, brick wall substrates, reduce construction waste and rework cost.
Superior Lubricating & Troweling Performance
Endow mortar with excellent plasticity, lower scraping resistance during wall plastering and skim coat construction, cut manual construction labor cost largely.
Uniform Dispersion Performance
Blend evenly with dry cement powder, disperse rapidly after adding water without local thickening lump, ensure finished mortar texture smooth and homogeneous.
Safe & Low-Risk Storage & Transportation
As stated in MSDS file, the product generates no toxic volatile substances, does not release harmful gas during construction. Only standard ventilation is required to avoid dust accumulation; it is classified as non-dangerous goods, no special hazardous cargo certification needed for sea/land shipping.
Specially customized for all mainstream dry-mix building compounds, no food, pharmaceutical or cosmetic grade application:
Interior & exterior wall skim putty, thin surface coating
Ceramic tile, marble slab vertical bonding mortar
EIFS external thermal insulation base coat and finishing mortar
Gypsum plaster, gypsum joint filler, gypsum self-leveling compound
Masonry brick bonding mortar, exterior wall rendering mortar
Cement-based self-leveling floor mortar
Crack repair mortar, waterproof gap caulking agent
