The core challenge in gypsum self-leveling formulation is a balancing act: good flow without bleeding, long open time without excessive retardation. HEMC plays a dual role in rheology control and water retention. But HEMC's viscosity and dosage directly affect setting time. Choose wrong, and you either lose flow or delay setting too much. A matching
Cracking in gypsum self-leveling is a shared headache for formulators and applicators. Drying shrinkage, substrate restraint, uneven moisture evaporation — any of these can become a crack origin. Among the many influencing factors, the choice of cellulose ether is often underestimated. HPMC or HEMC? The answer depends on how you weigh water retention against strength.
Gypsum‑based self‑leveling compounds are experiencing unprecedented market growth. By 2025, the overall self‑leveling mortar market in China is expected to exceed 40 billion RMB, with gypsum‑based products accounting for over 40% – up from less than 15% in 2020. Projections suggest this share could reach 50% by 2026. Behind this explosive growth, however, formulators face
Gypsum‑based self‑leveling compounds are widely used for their fast installation and excellent leveling performance. Yet, one persistent problem continues to frustrate contractors and manufacturers alike: surface dust. This loose, powdery layer not only looks bad—it also weakens the bond with subsequent floor coverings like epoxy or tile adhesives, leading to costly delamination. Fortunately, the solution
