Application:
1 construction industry: as cement mortar water retention agent, retarder mortar with pumping sex. Use mortar, gypsum, putty powder or other building materials as adhesives to improve daubability and prolong operation time. Use as paste ceramic tile, marble, plastic adornment, paste reinforces agent, still can reduce cement dosage. Hydroxypropyl methyl cellulose HPMC water retention performance so that slurry after smear will not dry too fast and crack, enhance the strength after hardening.
