KimaCell® HPMC MP40M is hydroxypropyl Methyl cellulose ether used to gypsum based plaster and gypsum mortar products. In gypsum-based slurry, hydroxypropyl methylcellulose mainly plays the role of water retention and thickening, and can effectively improve the adhesion and sag resistance of the slurry. High-quality HPMC MP40M can be uniformly and effectively dispersed in cement mortar and gypsum-based products, and wrap all solid particles, and form a wetting film, and the moisture in the base is gradually released over a long period of time, and the hydration reaction with the inorganic gelling material to ensure the bonding strength and compressive strength of the material.

Application of HPMC MP40M

KimaCell® HPMC MP40M can be used in cement based plaster.It has the bellow property:

  • Good construction performance: it is easy and smooth to hang, can be molded at one time, and has plasticity at the same time.

  • Strong compatibility: It is suitable for all kinds of gypsum bases, and can reduce the sinking time of gypsum, reduce the drying shrinkage rate, and the wall is not easy to hollow and crack.

  • Good water retention rate: it can prolong the operation time of gypsum base, improve the thickness resistance of gypsum base, increase the bonding strength between gypsum base and base layer, good wet bonding performance, and reduce landing ash and other problems.

  • Improve the spread rate of gypsum base: Compared with similar hydroxypropyl methylcellulose ether, the spread rate will be significantly increased. Hydroxypropyl methylcellulose products can greatly increase the coating rate, can cover more areas, can reduce labor intensity, save materials, and improve economic benefits.

  • Good anti-sagging performance: when hanging thick layers, single-pass construction will not sag, and more than two passes, above 3cm, will not sag when hanging, and the plasticity is good.
