Description: hydroxypropyl methyl cellulose ether (HPMC) is a natural polymer cellulose as raw material, through a series of chemical processing and made of non-ionic cellulose ether has been made, it is water-soluble, water sex, PH value stability, surface activity, temperature reversible gelling, thickening, binding, film forming, lubricating properties. Recommended for: tile adhesive powder coating inside wall putty plaster wall plaster mortar exterior insulation system hydroxypropyl methyl cellulose ether (HPMC) is a dry mortar additives very important, mainly played the role of water retention and thickening . Different types of cellulose varieties: Different varieties can be widely applied in different fields, such as construction, food and pharmaceutical industry, daily chemical industry, petroleum industry. Hydroxyethyl cellulose ether (HEC) and is mainly used in the coatings industry, oil drilling mud stabilizers, but its dispersibility, thickening and water retention were significantly lower than hydroxypropyl methyl cellulose ethers (HPMC). In the field of dry mortar, cellulose ethers (HPMC) is plastering mortar, plaster, tile adhesives, putty, self-leveling materials, injection mortar, wallpaper glue and caulking materials, an important modification of dry mortar material. In a variety of dry mortar, hydroxypropyl methyl cellulose ethers control mortar consistency, performance, adhesion properties and water retention. Hydroxypropyl methyl cellulose ethers (HPMC) in building materials with cement-based tile adhesives show an example. Plus there is added cellulose ether or cement-based tile adhesive, hydroxypropyl methyl cellulose ether gives the material as the adhesive properties which when coated tile adhesive will become more apparent.
