Hydroxypropyl Methyl Cellulose and Methyl Cellulose is a natural polymer cellulose as raw material, made of a series of chemical processing and non-ionic cellulose ether. They are an odorless, tasteless non-toxic white powder in cold water swelling into a clear or slightly muddy colloid solution. A thickening, bonding, dispersing, emulsifying, film, suspension, adsorption, gel, surface activity, such as maintaining water and protective colloid properties Hydroxypropyl Methyl Cellulose, Methyl Cellulose can be applied to building materials, industrial coatings, synthetic resin, ceramic industry, medicine. food. textile, agricultural, cosmetic and other industries

2. Granularity; The 100 mesh pass rate was more than 98.5%. The 80 mesh pass rate was more than 100%.

3. Carbonization temperature: 280-300℃

4. Apparent density: 0.25-0.70/cm3(usually around 0.5g/cm3), specific gravity: 1.26-1.31.

5. Color changing temperature: 190-200℃

6. Surface tension: 42-56dyn/cm in 2% aqueous solution.

7, soluble in water and some solvents, such as the appropriate proportion of ethanol/water, propanol/water, trichloroethane, etc. Aqueous solution has surface activity. High transparency, stable performance, different specifications of the product gel temperature is different, the solubility changes with the viscosity, the lower the viscosity, the greater the solubility, the performance of different specifications of HPMC has a certain difference, the dissolution of HPMC in water is not affected by PH value.

8. HPMC decreases with the decrease of methoxide content, gel point, water solubility, and surface activity.

9, HPMC also has thickening ability, salt-resistance low ash powder, PH stability, water retention, dimensional stability, excellent film formation, as well as a wide range of enzyme resistance, dispersion and bonding characteristics.

Building Materials Industry Application Guide

External wall insulation system(EIFS)

• Bond strength: Select the appropriate  Hydroxypropyl Methyl Cellulose can provide the greatest degree of high adhesive bond strength of mortar
• Performance: the use of distribution method, add the Hydroxypro psi Methyl Cellulose with mortar with the right consistency, not sagging, in use, making the mortar easy to comb, continuous. uninterrupted.
• Water retention: the ability to easily wetted wall insulation, easy to paste and make other additional materials to achieve the best results.
• Absorbent: Select the appropriate Hydroxypropyl Methyl Cellulose can minimize the air-entraining volume, lower water absorption of mortar
• Recommended brand: 75QR75000(S), 75QR100000(S), 75QR200000(S)

Interior and exterior bonding agents pointing agent

• Easy to mix, no agglomeration: water in the mixing process,  Hydroxypropyl Methyl Cellulose can significantly reduce friction in the dry powder to make it easier to mix, mixing time-saving.
• Excellent water retention: Hydroxypropyl Methyl Cellulose can significantly reduce the absorption of the water on the wall Good water retention, one can ensure the cement compound with a longer time. on the other hand. it can ensure that workers are able to carry out many putty on the wall scrape.
• Good construction performance stability: high-temperature environment Hydroxypropyl Methyl Cellulose can still maintain good water retention. it is suitable for construction in the summer or hot areas.
• Increased water demand: Hydroxypropyl Methyl Cellulose putty materials significantly improve the water demand volume, on the one hand, improve the putty on the wall of the operational time, on the other hand, can increase add putty coating area, so that formula is more economical.
• Recommended brand: 75QR60000(S), 75QR75000(S)

Tile abhesive

• Water retention: Hydroxypropyl Methyl Cellulose can be reduced by the substrate and the tile mortar smoke collection of water. the water retained in the binder as possible, making mortar coating after a long time remained adhesion. Significantly extend the opening hours, can work more people with each coating area, to improve construction efficiency.
• 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: 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: 75QR40000(S). 75QR75000(S). 75QR100000(S)

Crack Filler

• Workability：Hydroxypropyl Methyl Cellulose to provide the right viscosity, plasticity, and easy for working.
• Water retention：Hydroxypropyl Methyl Cellulose pulp can fully hydrated, to extend the facilities working time, to avoid cracking.
• Anti-hanging：Hydroxypropyl Methyl Cellulose can make a strong adhesion in the table surface, does not sag.
• Recommended brand: 75QR40000(S), 75QR75000(S)，75QR100000(S)

Self-leveling mortar

• Prevent bleeding：Hydroxypropyl Methyl Cellulose suspension can play a very good role to prevent the slurry sedimentation, bleeding.
• Maintain liquidity, to improve retention：low viscosity Hydroxypropyl Methyl Cellulose is not affecting 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：75QR400~600

Gypsum-based plaster

• Water retention：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 is coated with a thick coating without causing ripple building.
• Mortar yield： For fixed weight of dry mortar, the Hydroxypropyl Methyl Cellulose. The existence of temperature and mortar can produce more volume.
• Recommended brand: 75QR75000(S), 75QR100000(S)

Ceramic Extrusion

• 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 a delicate rounded surface of the product
• Recommended brand: 75QR4000~6000,75QR100000(S),65QR1500,60QR10000

Packing, storage and transportation matters needing attention
Woven bags with polyethylene film inside are packaged. The net weight of each bag is 25kg. It can prevent sunshine, rain, and moisture during storage and transportation.
