The Benefits of Using HPMC for Self-Leveling Mortar

Self-leveling mortar is a kind of polymer-modified cement that has high flow property, which is typically applied to interior big floor coverings, such as large shopping malls, supermarkets, industry workshops and etc. Yicheng cellulose ether plays an important role in self-leveling to achieve a smooth and flat surface with the key properties of anti-cracking, anti-shrinkage, preventing segregation, lamination, bleeding, etc.

Self-leveling mortar includes cement-based self-leveling mortar, self-leveling mortar, leveling mortar, etc.

 It is slightly expanded by a scraper to give a high level base surface. It can be used as a decorative surface and as a wear-resistant base layer.

it is a dry mixed powder material composed of a variety of active ingredients, which can be used by mixing water on site. 

HPMC for Self-Leveling

The high leveled base surface can be obtained after being slightly expanded by the scraper. The fast hardening speed and 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 mortars. The right amount of HPMC keeps the moisture in the mortar for a long time. Hydroxypropyl methylcellulose has a retarding effect on the mortar. As the cellulose ether content increases, the setting time of the mortar is prolonged.

Hydroxypropyl methylcellulose has a strong influence on the bonding properties of self-leveling mortars. Hydroxypropyl methylcellulose enhances the plasticity and flexibility of the mortar, reduces the stiffness of the transition zone between the mortar and the substrate, reduces the sliding ability between the interfaces, and to a certain extent enhances the bonding effect between the mortar and the substrate.

Applications of HPMC

Application to self-leveling function

1. Ensure the fluidity of the self-leveling mortar.

2. Improves the self-healing ability of the self-leveling mortar.

3. Helps to form a smooth surface.

4. Reduces shrinkage and increases load-bearing capacity.

5. Improves the adhesion and cohesion of the self-leveling mortar to the substrate.

Features of Products:

• Good consistency

• Good anti-bleeding

• High adhesion strength

• Anti-crack, anti-shrinkage

• High adhesion strength

It also imparts good workability. The selected particle size distribution guarantees quick or lump free dissolution. It is compatible with all conventional mineral and organic binders.

More Information about HPMC Products:

5. Highly modified products: Imported technology offers better properties like water retention, slip resistance, crack resistance, longer open time, etc. Widely used in Tile adhesives, Wall Putty, Mortars, Gypsum based products, etc.

Yicheng offers the grade HPMC for self-leveling to improve the properties of preventing segregation, lamination, open time, crack resistance, workability and so on.

Our low-viscosity products are suitable for self-leveling applications, which can enhance fluidity and pumpability, thereby improving floor efficiency, control water holding capacity, make water seepage less obvious, and having high formation strength and small shrinkage after drying, thereby greatly reducing cracks.
