HPMC for self leveling application

Self leveling mortar includes cement～based self leveling mortar, self leveling mortar, leveling mortar, etc. it is a dry mixed powder material composed of a variety of active ingredients, which can be used by mixing water on site. The high leveled base surface can be obtained after being slightly expanded by the scraper. The fast hardening speed, fast and simple construction are incomparable to the traditional manual leveling, which can be used as the decorative surface course and wear～resistant base course.

Hydroxypropyl methyl cellulose has an important influence on the water retention, consistency and workability of self leveling mortar. A reasonable amount of HPMC can keep the moisture in the mortar for a long time. Hydroxypropyl methyl cellulose has a certain retarding effect on mortar. With the increase of cellulose ether content, the setting time of mortar will be prolonged.

Hydroxypropyl methylcellulose has a great influence on the bonding performance of self leveling mortar. Hydroxypropyl methylcellulose can enhance the plasticity and flexibility of mortar, reduce the rigidity of the transition zone between mortar and substrate, reduce the sliding ability between interfaces, and enhance the bonding effect between mortar and substrate to a certain extent.
