MHEC
Hydroxyethyl methyl cellulose (HEMC) is a non-ionic, water-soluble cellulose ether. It is produced from natural cotton linters or wood pulp cellulose through a dual modification process involving methylation and hydroxyethylation, yielding a white powdered polymeric additive.

Product Specifications
- Form: White/off-white fine powder, free of impurities and hard lumps.
- Odor: Odorless and tasteless, environmentally friendly and non-toxic.
- Solubility: Dissolves rapidly in cold water; does not gel in hot water; the aqueous solution is clear, transparent, and viscous.
- Aqueous solution pH: 6–8, stable pH range, excellent resistance to metal ions and salinity.
- Mold resistance: The hydroxyethyl group imparts long-lasting antibacterial and antifungal properties, with minimal viscosity loss during prolonged storage.
Product Performance
- 1. Exceptional water-retention capability
It locks in system moisture, preventing rapid water loss from mortar or putty; it also prolongs hydration time, thereby reducing powdering, cracking, and delamination on wall surfaces. Its advantages are particularly pronounced when applied in hot, dry conditions. - 2. Thickening and anti-slip
It adjusts the rheology of the slurry, ensuring that tile adhesive does not slip off the wall and thick putty does not sag, thereby enhancing vertical application stability. - 3. Extended Opening Hours
Keep the slurry surface moist, allowing ample time for tile installation and putty application to minimize rework. - 4. Easy-to-apply lubrication
Enhances the smoothness of mortar, making troweling and spraying easier; it resists delamination and bleeding, with significantly improved workability. - 5. Film formation, adhesion, and suspension stability
It dries to form a flexible film, enhancing adhesion; in coatings, it disperses pigments, prevents settling, and inhibits splattering.
Application areas
- 1. Dry-mix building materials
- Tile adhesives and grouts: slip resistance, water retention, and extended tile‑setting adjustment time.
- Interior and exterior wall putty: crack-resistant, non‑powdery, and smooth to apply
- Gypsum products (leveling and joint-filling gypsum): slow-setting, water-retaining, with a fine surface finish.
- Waterproof mortar, plastering mortar, and self-leveling cement: enhance workability and improve long-term strength. - 2. Water-based paint/latex paint
Thickens, prevents sagging, suspends pigments, and enhances film uniformity; brushes on without splattering. - 3. Daily chemicals, pharmaceuticals, and inks
Thickening and stabilizing agent for shampoos, toothpastes, and topical ointments; water-retaining and anti-drying additive for printing inks. - 4. Oil Drilling
Drilling fluid thickening, sand-carrying, and fluid-loss-reducing additive.
