Cellulose Ether Hypromellose HPMC as bonding agent for Construction Application
Description:
Non-ionic cellulose ether HPMC is a kind of semisynthesis, inactive and viscoelastic polymer. Its appearance is white powder with colourless and tasteless. It can be used as thickening agent, dispersion agent, bonding agent, excipient, emulgator and stabilizer. With the development of cellulose production technology and excellent properties of construction grade HPMC, it was used widely in the construction industry. The yield and consumption of HPMC are increased sharply in recent years.

HPMC has the effect of thickening, water retaining and construction in putty powder.
1. HPMC can thicken and make the solution uniform. Then avoid sagging.
2. HPMC makes putty powder dry slower and help ash calcium powder react in water.
3. Construction: HPMC has lubrication action, which makes putty powder has a good condition for construction.
Characters:
1. 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 MC. The dissolving condition in cold water is also much better than MC.
2. 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 much. The viscosity will be lower with the rise of temperature. But temperature has a smaller influence to the viscosity than MC. So the solution of HPMC is stable in room temperature.
3. The water retaining properties of HPMC depend on the dosage and viscosity. The water retation rate is higher than MC in the same dosage.
4. HPMC is stable to acid and alkali. Its aqueous solution with PH between 2 and 12 is very stable. Caustic Acid and whitewash has a small influence to HPMC properties. But alkali can quicken its speed of dissolving and increase the viscosity slightly. HPMC is also stable to normal salts. But if the concentration of salt solution is high, the viscosity of HPMC solution has a trend of increasing.
Properties:
1. Water retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking.
2. Adhesivity: It can make mortar attach to base material better sincethe plasticity of mortar is enhanced.
3. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
Storage:
It should be kept away from exposure to the sun, rain and moisture in storage and transportation.
Packaging: 25kg/Bag or according to the requests of the customers. It can load 25MT in one 40'GP container.
