HPMC MP15M

Specification of HPMC MP15M

Application of HPMC MP15M

KimaCell^® HPMC MP15M can be used in standard tile adhesive. It has the bellow property on bellow point:

Influence on the open time of tile adhesive

When latex powder and cellulose ether HPMC co-exist in wet mortar, some data models show that RDP powder has stronger kinetic energy to attach to cement hydration products, and cellulose ether exists more in the interstitial fluid, which affects more Mortar viscosity and setting time.

Influence on the pull-out strength of tile adhesive

In addition to imparting the above-mentioned beneficial properties to mortar, cellulose ether also delays the hydration kinetics of cement. This retarding effect is mainly due to the adsorption of cellulose ether molecules on various mineral phases in the cement system being hydrated. Cellulose ether molecules are mainly adsorbed on hydration products and rarely adsorbed on the original mineral phase of the clinker. In addition, the cellulose ether reduces the mobility of ions in the pore solution due to the increase in the viscosity of the pore solution, thereby further retarding the hydration process.
