Our WalocelŪ MKX product line comprises methyl hydroxy ethyl cellulose grades with a medium to high degree of etherification, which provide building materials with high water retention even at high wet mortar temperatures of 3040°C. This ensures that the building materials are workable in a warm climate or when immediately using freshly burnt gypsum or heat-dried sand.
The water retention capability of WalocelŪ MKX is virtually constant between 20 and 40°C. More detailed information is given in our brochures on gypsum or cement based plaster.
WalocelŪ MKX is mainly used in mineral based building material systems and provides the following benefits:
- rapid thickening and build-up of water retention capability
- high water retention even at high wet mortar temperatures
- good pump ability for machine-applied systems
- high standing strength of plaster systems
- easy workability (levelling, distribution) and creaminess
- high standing strength, slip resistance (anti-sag properties) and open time of tile adhesives
- high ultimate strength ratings
WalocelŪ MKX products are produced as fine or very fine powders. By matching the grain size (particle size) to the requirements of the individual building material system, the consistency and water retention can be precision-adjusted in respect of the time-related build-up of these features. The products are available in viscosity between 6000 and 60000 mPa·s an.
