HPMC is a kind of white colored powder made from refined cotton and chemicals, it is widely used in Tile Adhesive, Wall Putty, self leveling, plasters, renders, docrative mortar and other construction materials. It has the advantages of Water Retention, Easy Construction, and smooth wall formed.
The effect of HPMC in dry mixed mortar
In the production of building materials, especially dry mixed mortar, cellulose ether plays an irreplaceable role, especially in the production of special mortar (modified mortar), is an indispensable and important part.

1) Easy mixing without lump formation
SLEO cellulose ethers as additives are vital when dry powder products are mixed by hand. The lubricating properties of SLEO cellulose ethers reduce friction between particles, saving time and making thorough dispersion easier.
2) Improved workability
The lubricity of Celotech cellulose ethers improves workability, making spreading easier and increasing efficiency. Users also prefer the “feel” that cellulose products give to tile adhesives and grouts.
3) Good water retention
Cellulose ethers increase the water retained by the adhesive, minimizing the amount absorbed by the substrate and by the tile. This prolongs open time, and brings gains in productivity because the adhesive can be applied to a wider area. SLEOcellulose also can extend shelf life and pot-life of ready-mixed adhesives, prolonging their usefulness.
4) Enhanced adhesion and sliding resistance
SLEO cellulose products enhance adhesion, even at high ratios of water to solids, ensuring a better result and preventing sagging. SLEO additives can help your products resist sliding, a benefit that tile setters will appreciate.
5) Heat resistance
Redispersible polymer powders can be included in formulations using SLEO cellulose ethers to ensure that adhesives offer bonding strength after exposure to heat.
