Technical overview of AkzoNobel's Bermocoll cellulose ether products for tile adhesive, mortar and grout applications.
The Bermocoll product family, developed by AkzoNobel, is a high‑performance cellulose ether used in construction materials such as tile adhesives, mortars and grout. It improves water retention, workability, stability and bond strength of cement‑ and gypsum‑based systems.
The leaflet describes the main types (EHEC, MEHEC, CCA, BCM/CCM/ML), their viscosity ranges, particle sizes, solubility conditions and performance data, and provides formulation recommendations for various building applications. This manual is written in Chinese.
| Viscosity (1 % solution, 20 °C) – M 10 | 1000 mPa·s |
|---|---|
| Viscosity (1 % solution, 20 °C) – M 800 X | 11000 mPa·s |
| Water retention after 7 days at 100 °C | ≈94 %–95 % |
| Solubility pH condition (FQ grade) | pH ≤ 7 (cold water) |
When stored at 100 °C for 7 days, Bermocoll retains about 94 %–95 % of its water‑holding capacity.
FQ‑grade Bermocoll can be dispersed in cold water at pH ≤ 7.
