Product Description The English abbreviation of hydroxypropyl methylcellulose is HPMC, which is a non-ionic cellulose ether with a molecular formula of C56H108O30. CAS 9004-65- 3, odorless, tasteless, white powder. Hydroxypropyl methylcellulose (HPMC) absorbs moisture after drying but is stable. The solution is stable at pH 3-11. As the temperature increases, the viscosity of the solution decreases. Heating-cooling can reversibly transform HPMC from a solution state to a gel state. According to different grades and concentrations, the gel temperature is 50～90℃. HPMC water solution has anti- enzyme effect and maintains good viscosity stability during long-term storage. However, its aqueous solution is susceptible to microbial attack, so preservatives should be added during storage. When HPMC is used as a thickening agent in eye drops, benzalkonium chloride is usually added as a preservative.

Product Description HPMC is made from mature polymer cellulose through a series of chemical processing. It is used in various applications in the construction, food, pharmaceutical and personal care industries. Depending on the application, it can be used as a thickener, adhesive, film-forming agent, water-retaining agent, suspending agent and lubricant. HPMC Features HPMC use for 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. Exterior Insulation and Finish System ( EIFS ) Improved adhesion. Good wetting ability for EPS board and substrate. Reduced air entrancement and water uptake

Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Hydroxypropyl Methylcellulose Description No primer or curing required thus there is considerable cost saving Protects expensive paints from moisture and flaking Highly durable and water resistant Prevents the growth of algae and fungus Economical and long lasting Dissolution Method(HPMC) 1. Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Goon stirring until it cools down and becomes clear 2. Another way is by heating the amount of 1/3 or 2/3 water to above 85℃, add the cellulose to obtain hot slurry, then add the remaining cold water and keep stirring, the mixture is obtained when the slurry cools to about 20 ℃
