HPMC is short name of hydroxypropyl methyl cellulose. It is a kind of multifunctional additive. Its main effects are water retention and thickening. It also have features of adhesion, dispersion, emulsification, film forming, suspension, adsorption, gel, surface activity and protective colloid.
As a result of its multifunctional, It has a quite widely usage.
HPMC used in Cement-based plastering Mortar
1,HPMC can improve the uniformity of plastering mortar, making it easy to coating, at the same time improve the ability of anti-sag. It can also boost liquidity and pumpability of mortar, to improve the work efficiency.
2, With high water retention, HPMC can prolong the working time of mortar, improve work efficiency, and help the mortar in obtaining high mechanical strength in solidification period.
3, HPMC can control air infiltration, to eliminate the tiny cracks of coating, to format the ideal smooth surface.
