Beschreibung
Zusammenfassung:The present invention provides dry mix compositions for cement-based tile adhesives having both improved open time and slip resistance comprising one or more gel-like crosslinked cellulose ethers containing polyether groups, preferably, a mixed cellulose ether having polyoxypropylene dioxyethylene ether crosslinks. The gel-like water-soluble crosslinked cellulose ethers containing polyether groups of the present invention are formed from low to medium viscosity cellulose ethers and contain polyether groups having from 2 to 15, or, preferably, 13 or fewer oxyalkylene groups, or, preferably, 7 or more oxyalkylene groups. The present invention also provides methods of using the dry mixes in cement-based tile adhesives.
