Hydroxyethyl methyl cellulose ether, referred to as HEMC, is a non-ionic cellulose ether obtained from natural polymer material cellulose through a series of chemical reactions. It is an odorless, tasteless, non-toxic white to off-white powder or granule, which can be dissolved in cold or hot water to form a transparent viscous solution, which has the functions of thickening, binding, water retention, dispersion, emulsification and film formation.

Hydroxypropyl methylcellulose (HPMC) and hydroxyethyl methylcellulose (HEMC) are widely used building materials, when applied to gypsum-based plastering, it has the following characteristics:Water Retention: Retains in the mortar, allowing the gypsum to fully set.

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

Hydroxyethyl methyl cellulose (HEMC) is widely used in water-based latex coatings, building construction and building materials, printing ink, oil drilling and other aspects, play the role of thickening water retention, improve the construction, used in wet and dry mortar series products.  Its properties are similar to methyl cellulose, but because of the presence of hydroxyethyl makes hydroxyethyl cellulose more soluble in water, the solution is more compatible with salt, and has a higher condensation temperature.Structural formula (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]n
