Hydroxyethyl methyl cellulose(HEMC)For Construction
●Improves uniformity, makes plastering easier to apply, and increases resistance to downdraft. Enhance fluidity and pumpability to improve work efficiency.
●Air infiltration is controlled, thus eliminating micro-cracks in the coating and forming the ideal smooth surface.
●Make the dry mixing ingredients easy to mix, will not produce clumps, thus saving the working time, because the application is faster and more effective, can improve the construction and reduce the cost.
Hydroxyethyl methyl cellulose ether soluble in water and some organic solvents. Can be dissolved in cold water, its highest concentration is determined only by viscosity, solubility changes with viscosity, the lower the viscosity, the greater the solubility. Because the aqueous solution has surface active function, can be used as colloid protectant, emulsifier and dispersant, the highly concentrated aqueous solution of the product has special viscoelastic properties compared with the aqueous solution of other polymers, and its addition has the ability to improve the shape of extruded ceramic products.
