HPMC-Hydroxypropyl Methyl Cellulose and Methyl Hydroxyethyl Cellulose and non-ionic cellulose ether made by natural high polymer cellulose as raw material and series of chemical processing.They are odorless,tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution.Processing thickening,binding,dispersing,emulsifying,film coating,suspending,absorbing,gelling,surface activity,water maintaining and protective colloid properties.
1. Construction industry: as a water-retaining agent and retarder of cement mortar, mortar has pumpability. Apply mortar, plaster, putty powder or other building materials as adhesives to improve spreadability and extend operating time. Used to paste ceramic tile, marble, plastic decoration, paste enhancer, can also reduce the amount of cement. Hydroxy propyl methyl cellulose HPMC water retention properties make the paste after application will not dry too fast and crack, enhance the strength after hardening.
