Description:lose Ether is a hydroxypropyl methyl lose (HPMC) with delayed solubility.      2%solution,20ºC,mpa.sBrookfield,LV,1%solution,25ºC,mpa.s       Application:Construction industry: As a water-retaining agent and retarder for cement mortar, themortar can be pumped. In plastering, gypsum, putty powder or other building materials as adhesives, improve the daub and extend the operating time. Use as stickup ceramic tile, marble, plastic adornment, stickup aggrandizement agent, still can reduce cement dosage. HPMC water retention performance so that paste in the application will not dry too fast and crack, enhance the strength after hardening. Ceramic manufacturing industry:widely used as adhesive in ceramic product manufacturing.
