The main advantages of SLEO HPMC, MHEC in dry mix mortar:

building grade HPMC can significantly reduce the water absorbed by the wall and has good water retention. On the one hand, it can ensure that the cement has a longer compounding time. On the other hand, it can ensure that workers can scrape the putty on the wall multiple times. To ensure the quality of building.

As the most important part of building materials commercialization, SLEO HPMC plays a vital role in masonry and plastering mortar. A good mortar should have good workability, smooth application without sticking, sufficient operating time, and easy leveling;

As we all know, tile adhesive is generally made from cement and mixed with various additives. It is mixed with water at the construction site and then applied to the wall or floor. It generally has a certain initial strength about 12 hours after construction. The strength increases with time and is generally basically stable after 28 days.

After the putty has dried and been de-powdered, the root cause can be attributed to the fact that the bonding system did not work. Why the bonding system, whether it is an inorganic binder or an organic binder, can be considered from the following aspects.

Under the wet-mixture situation, RDP would improve the thickness and slipperiness of the mortar system. The characters of the polymer itself make a big difference on mortar’s cohesion and workability.
After Tile Adhesive dried, RDP would also enhance the adhesion on the smooth and compact surface, and improve the effect of sandstone’s interface air vent. With enough RDP dosage, it would form a film on the interface which makes Tile Adhesive be flexible by lower the elasticity modulus.

HPMC is white powder or granule made from highly pure cotton – cellulose by reaction of etherification. HPMC is characterized by water solubility, water retention, nonionic, stability of the PH value, surface activity, temperature reversible gelling properties, thickening property, film formability, lubrication property etc.,without any organs of animals, fat and other bioactive constituents.

HPMC for putty powder is thickening agent and water-retaining agent. It also makes the construction more easier.

Dry blending: In the case of other powders, it should be mixed well with the powder and then added with water to dissolve quickly and not agglomerate.
