HPMC

Hydroxypropyl Methyl Cellulose is a kind of non-ionic cellulose ether made from natural polymer materials through a series of chemical processing. It is odorless, tasteless, non-toxic white powder that dissolves in cold water to form transparent viscous solution. Properties of thickening, bonding, dispersion, film formation, suspension, absorption, gels surface activity, moisture retention and protective colloid.

Application

Construction industry: as a water-retaining agent and retarder for cement mortar, the mortar 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.
