Hydroxypropyl Methyl Cellulose For Plaster Application: Industrial

1.Brief Introduction
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.

3.HPMC for Plaster:
Sheng Laiou HPMC can significantly improve the construction performance of gypsum based products. Custom-made HPMC for gypsum for professional building facilities etc. Good viscosity and ductility, good smoothing, dispersion and water retention with the addition of cellulose ether, thus enhancing the bond of the substrate.

HPMC for Plaster Typical application
a Handy gypsum plaster
a Sprayed gypsum render
a Interior finishing / Skim coat plaster

HPMC for Plaster Advantage
-Increasing the thelloxotropy
-Improving fluidity and pumpability
-Extending the open time
-Enhancing the mechanical strength
