HPMC plays three roles in the putty powder, including thickening, water retention and construction. Thickening: Cellulose can be thickened to suspend, keep the solution uniform, and resist sagging. Water retention: Make the putty powder dry slowly, and assist the reaction of ash calcium under the action of water. Construction: Cellulose has a lubricating effect, which […]

Hydroxypropyl methyl cellulose is a kind of nonionic cellulose ether, which is made from natural plant macromolecular cellulose through a series of chemical processing. It is an odorless, tasteless, non-toxic white powder. Soluble in cold water and organic mixtures. In the production process of hand sanitizer, adding an appropriate amount of hydroxypropyl methyl cellulose can […]

1. Problems existing in the application of self-compacting concrete Self-compacting concrete has been widely used in engineering because of its excellent working performance, but there are also some problems in the application process, the more prominent ones are as follows: (1) The requirements for raw materials are too high, and the production is difficult to […]

1. Putty (Skim coating) In the whole coating process, the important role of putty is: a. Eliminate the surface defects of the coating base and improve the flatness of the base b. Plays a bonding transition role between the base layer and the coating film As the three levels of the painting process: the wall, […]

Methyl cellulose MC and hydroxypropyl methyl cellulose (HPMC) have stable chemical properties. Mildew resistance and water retention are not affected by changes in pH. Viscosity can be used between 50,000 and 200,000, but in production, higher viscosity is better. Viscosity is inversely proportional to bond strength. The higher the viscosity, the lower the strength. Regarding […]

MC is a kind of methyl cellulose, which is obtained by treating refined cotton with alkali and using MC as etherification agent through a series of reactions to generate cellulose ether.The degree of substitution is generally 1.6 to 2.0, depending on the solubility. HPMC is hydroxypropyl methyl cellulose, is refined cotton alkalization, with acetal oxide […]

The content of redispersible polymer powder include: polymer powder, additives, protection colloid and anti-caking agent. ● polymer powder: It is the key content of redispersible polymer powder and provide the key properties of redispersible polymer powder in applications. For example Maissen RDP products is based on VEA(vinyl ethylene acetate copolymers). ● Protection colliod: It is a kind of […]

Cellulose ether HPMC(hydroxypropyl methyl cellulose) and MHEC(Methyl hydroxy ethyl cellulose) in dry mortar:  The water retention of cellulose ether(HPMC,MHEC) comes from its own solubility and dehydration. Although the molecular chain of cellulose contains a lot of hydroxyl groups with strong hydration properties, it is not soluble in water, This is because the cellulose structure has a […]

The main advantages of Mailose HPMC, MHEC in dry mix mortar: Wall putty/Plaster: • Sag-resistance: Mailose HPMC, MHEC can provide a good viscosity of the wet mortar, prevent wall putty sagging. • The good filming property on the surface of wall putty, could reduce the water absorption of base wall. Reduce the risk of cracking. […]
