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.

HPMC is non-ionic cellulose ether, appearance is white powder, odorless and tasteless, soluble in water and most polar organic solvent and suitable proportion of ethanol / water, propanol / water, two trichloroethane, insoluble in ether, acetone, ethanol, in cold water swelling into colloidal solution clear or slightly turbidity. Aqueous solution with surface activity, high transparency, […]

HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.

CMC and HPMC can be added to mortar to maintain moisture and thickening.As the dosage increases, the level of mortar will be reduced.CMC is an ionic cellulose ether that can react with the Ca (OH) 2 when added to the mortar.There is no obvious improvement in the water retention performance of CMC,
