I’ve toured enough paint plants and mortar lines to know what wins the day: predictable rheology, clean mixing, and coatings that don’t sag on a humid Thursday. That’s exactly where YoungCel’s construction-grade MHEC—made in ShiJiaZhuang, HeBei, at No.1 Shifu East Road, Gaocheng District—has been sneaking into specs. In fact, many customers say it feels like a safe switch from HPMC when they want longer open time without sticky roller drag.
| Chemistry | Methyl Hydroxyethyl Cellulose (MHEC), CAS 9032-42-2 |
| Appearance / Color | White to cream, free-flowing powder |
| Viscosity (2% aq, 20°C, Brookfield) | ≈ 45,000–65,000 mPa·s (real-world use may vary) |
| pH (1% solution) | 6.0–8.5 |
| Moisture | ≤ 5% |
| Ash content | ≤ 3% |
| Gel temperature | ≈ 60–75°C |
| Recommended dosage | 0.2–0.6% on total paint/mortar mass |
Base cellulose is purified, then etherified with methyl chloride and ethylene oxide under controlled alkalinity. After neutralization, washing, drying, and milling, lots are sieved for particle consistency. Honestly, the boring part is the most important: QC.
A mid-size coatings maker told me their roller spatter fell by roughly 20% after switching to Factory Sale Construction Grade MHEC Technical Grade for Paint Cellulose Ether MHEC. Not a lab miracle—just fewer callbacks.
Latex interior matte, PVC ≈ 62%. Swapped legacy HPMC for Factory Sale Construction Grade MHEC Technical Grade for Paint Cellulose Ether MHEC at 0.35% dosage.
| Vendor | Purity/Consistency | Lead Time | Certifications |
|---|---|---|---|
| YoungCel (China) | High; tight moisture window | Around 2–3 weeks | ISO 9001; REACH-ready SDS |
| Generic import | Variable batch-to-batch | 3–6 weeks | Mixed/partial |
| Local blender | Good, depends on feedstock | 1–2 weeks | Varies |
If you need a cellulose ether that behaves on the mill and behaves on the wall, Factory Sale Construction Grade MHEC Technical Grade for Paint Cellulose Ether MHEC is, I guess, the practical pick.
