Specification of HPMC MP20M

Application of HPMC MP20M

KimaCell^® HPMC MP20M can be used in cement based plaster. It has the bellow property on bellow point:

• After the HPMC in the mortar is dissolved in water, the effective and uniform distribution of the cementitious material in the system is ensured due to the surface activity, and HPMC, as a protective colloid, "wraps" the solid particles and forms a layer on its outer surface. A layer of lubricating film makes the mortar system more stable, and also improves the fluidity of the mortar during the mixing process and the smoothness of construction.

• Due to its own molecular structure, the HPMC solution makes the water in the mortar not easy to lose, and gradually releases it over a long period of time, endowing the mortar with good water retention and construction. It can prevent the water from flowing too quickly from the mortar to the base, so that the retained water stays on the surface of the fresh material, which can promote the hydration of the cement and improve the final strength.

• HPMC is stable to acid and alkali, and its aqueous solution is very stable in the range of pH=2~12. Caustic soda and lime water have little effect on its performance, but alkali can speed up its dissolution and slightly increase its viscosity.

• The construction performance of the mortar added with HPMC has been significantly improved. The mortar seems to be "oily", which can make the wall joints full, smooth the surface, make the tile or brick and the base layer bond firmly, and can prolong the operation time, suitable for large Area construction.
