HPMC can improve the uniformity of plastering mortar, making it easy for coating applications. At the same time it can also boost liuquidity and pumpability of mortar, to improve work efficienct. In therms of tile adhesives, It is easily mixed with water without lump appearing, thus saving time. The water retaining property of HPMC extend the drying time of mortar, so as to improve the efficiency of mixing. As for Gypsum based plastering products, It can keep up with the consistency.
Our product grades can be used for a variety of applciations. Several products may be used for Cosmetics, Cement renders, and gypsum products. HPMC can also improve the adhesiveness between mortar and mansory, and the water retaining property of HPMC is useful in raising the strength of mortar.
Tile cement mortar, this model can be advantagous because it improves water retention, workability, sag resstance. Especially helps to increase adhesion strength and open time.
Application
1. Construction industry: As a water retention agent and retarder for cement mortar, the mortar has pumpability. Used as a binder in plastering plaster, gypsum material, putty powder or other building materials to improve the spreadability and extend the operating time. It can be used to paste ceramic tiles, marble, plastic decoration, paste enhancer, and can also reduce the amount of cement. HPMC's water-retaining properties prevent the slurry from cracking because it dries too quickly after application,
enhancing the strength after hardening.
2. Ceramic manufacturing industry: widely used as a binder in the manufacture of ceramic products.
3. Coating industry: As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. As a paint remover.
4. Ink printing: as thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
5. Plastic: used as a mold release agent, softener, lubricant, etc.
6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride, and is the main auxiliary for the preparation of PVC by suspension polymerization.
7. Other: This product is also widely used in leather, paper products industry, fruit and vegetable preservation and textile industry.
8. Pharmaceutical industry: coating materials; film materials; speed-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; tackifiers
