3. Application fields:

1）Tile Adhesives

•Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.

•Good water retention: prolonged opening time will make tiling more efficient.

•Improved adhesion and sliding resistance: especially for heavy tiles.

2）Dry mixed mortar

•Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.

•Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.

3）Cement/Gypsum based Plaster

•Increased water demand: increased open time, expanded spry area and more economical formulation.

•Easier spreading and improved sagging resistance due to improved consistency.

4）Wall putty/Skimcoat

•Water retention: maximized water content in slurry.

•Anti-sagging: when spreading a thicker coat corrugation can be avoided.

•Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.

5）Exterior Insulation and Finish System ( EIFS )

•Improved adhesion.

•Good wetting ability for EPS board and substrate.

•Reduced air entrancement and water uptake.

6）Self-leveling

•Protection from water exudation and material sedimentation.

•No effect on slurry fluidity with low viscosity

HPMC, while its water retention characteristics improve the finish performance on the surface.

7）Crack Filler

·Better workability: proper thickness and plasticity.

·Water retention ensures prolonged work time.

·Sag resistance: improved mortar bonding ability.
