• Improve bond strength, improve anti-slip performance:  Hydroxypropyl Methyl Cellulose grades, to ensure that the construction of tile will not fall, especially for heavy-duty porcelain brick, marble and other stone.

• Work performance: HOSEACHEM@ Hydroxypropyl Methyl Cellulose, significantly increased lubricity sand pulp of the work, so that is easy to sort out the steamed bread coated with mortar to improve efficiency.

• Improve the mortar wetting: Hydroxypropyl Methyl Cellulose to give mortar consistency, improve mortar and tile and substrate wetting, improves the wet mortar bond strength, especially in high water-cement ratio formula.

• Recommended brand: 75HS40000(S), 75HS75000(S), 75HS100000(S)

(4) Crack Filler

• Workability: HOSEACHEM Hydroxypropyl Methyl Cellulose to provide the right viscosity, plasticity, and easy for working.

• Water retention: HOSEACHEM Hydroxypropyl Methyl Cellulose pulp can fully hydrated, to extend the facilities working time, to avoid cracking.

• Anti-hanging: HOSEACHEM Hydroxypropyl Methyl Cellulose can make a strong adhesion in the table surface, does not sag.

• Recommended brand: 75HS40000(S), 75HS75000(S), 75HS100000(S)

(5) Self-leveling  mortar

• Prevent bleeding: HOSEACHEM Hydroxypropyl Methyl Cellulose suspension can play a very good role to prevent the slurry sedimentation, bleeding.

• Maintain liquidity, to improve retention: low viscosity HOSEACHEM Hydroxypropyl Methyl Cellulose is not affect the slurry flow effect, ease of construction. Also have some water retention, so after the surface was self-leveling effect, to avoid cracks.

• Recommended  brand:  75HS400~600

(6) Gypsum-based plaster

• Water retention: HOSEACHEM Hydroxypropyl Methyl Cellulose to retain moisture within the mortar, thus making stone cream has been completely solidified. The higher the viscosity, the stronger the water-retention capacity, on the contrary, Poor water ability.

• Sag resistance: allow the construction are coated with a thick coating without causing ripple building.

• Mortar yield: For fixed weight of dry mortar, the HOSEACHEM Hydroxypropyl Methyl Cellulose. The existence of temperature and mortar can produce more volume.

• Recommended brand: 75HS75000(S), 75HS100000(S)

(7) Ceramic Extrusion

• HOSEACHEM Hydroxypropyl Methyl Cellulose can provide good lubricity and plasticity, can be fully put tire mold for ceramic products operational.
  

• Very low ash content in the product after calcination has a very dense internal structure, while delicate rounded surface of the product.

• Recommended brand: 75HS4000~6000, 75HS100000(S), 65HS1500, 60HS10000

Hydroxypropy Methyl Cellulose Ether (HPMC) is widely used as a thickener, stabilizer and water retaining agent for building materials. It provides water retention and workability for mortars, it can improve adhesion, reduce skinning and increase open time.HPMC also has thickening ability, low ash content, PH stability, water retention, excellent film forming, and extensive enzyme resistance, dispersion and so on.

Cellulose HPMC Good Water Retention And High Hpmc Viscosity Without Agglomeration.

HPMC is easily dissolved in cold water and a little hard in hot water. But its gelation temperature in hot water is abviously higher than cold water. 
The viscosity of HPMC is related to its molecular weight. The bigger the molecular weight, the higher the viscosity. The temperature also influences the viscosity. The viscosity will be lower with the rise of temperature.
