(1) hydroxypropyl methyl cellulose is easy to dissolve in cold water, and it will be difficult to dissolve hot water. But the gelation temperature in hot water is obviously higher than that of methyl cellulose. The dissolution of water in cold water is also much better than that of methyl cellulose.

(2) the viscosity of hydroxypropyl methyl cellulose is related to the size of the molecular weight, and the viscosity of the methyl cellulose is high. The temperature also affects the viscosity, the temperature and the viscosity. But the effect of high viscosity on the temperature is lower than that of methyl cellulose. The storage of the solution at room temperature is stable.

(3) the water retention of hydroxypropyl methyl cellulose depends on its addition and viscosity, and the water retention rate under the same dosage is higher than that of methyl cellulose.

(4) hydroxypropyl methyl cellulose has stability to acid and alkali, and its aqueous solution is very stable in the range of pH=2~12. Caustic soda and lime water has little effect on the performance, but can accelerate the dissolution of alkali, and improve the viscosity of pin. Hydroxypropyl methyl cellulose has stability to general salt, but the viscosity of HPMC is higher when the concentration of salt solution is high.

(5) hydroxypropyl methyl cellulose (HPMC) can be mixed with water-soluble polymer to become a homogeneous and higher viscosity solution. Such as polyvinyl alcohol, starch ether, plant gum and so on.

(6) hydroxypropyl methyl cellulose has better resistance to enzyme than methyl cellulose, and the possibility of enzyme degradation in solution is lower than that of methyl cellulose. The adhesion of hydroxypropyl methyl cellulose to mortar construction is higher than that of methyl cellulose.

Cement based render(plaster/mortar) is the mixture of suitable sand, cement and water which is generally applied to masonry interiors and exterior to smooth wall surface. Yicheng HPMC plays a key role in cement based render(plaster/mortar) to achieve the excellent performance of water retention, open time, workability, crack resistance, sag resistance, etc.

HPMC For Cement Based Render/Plaster/Mortar, Good Water Retention, Better Workability, Crack Resistance, Sag Resistance.

    Description      

HPMC For Cement Based Render/Plaster/Mortar, Good Water Retention, Better Workability, Crack Resistance, Sag Resistance

Due to the difference of region and raw materials, different customers require different HPMC for cement based render/plaster/mortar. Yicheng can offer two kinds of HPMC for this application to improve the properties of water retention, anti-crack, anti-sag, workability, etc.

The modified grade H150000 is specially developed for cement-based applications, like Single layer coat, skim coat, cement plaster. 

The unmodified grade L150000 is economic options, which can also achieve the general required properties of wall putty or skim coat.
