GYPSUM COMPOSITIONS CONTAINING CROSSLINKED CELLULOSE ETHERS FOR MORTARS WITH REDUCED STICKINESS

摘要

The present invention provides dry mix compositions for use in making gypsum plasters or mortars comprising gypsum, preferably, phosphorous gypsum one or more retarder, and one or more crosslinked cellulose ethers containing polyether groups. The compositions enable the provision of gypsum dry mixes, such as those from phosphorus gypsum, that make gypsum mortars with less stickiness while reducing the amount of cellulose ether in the dry mix.
