Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.
Product properties
1. Water Retention: The water retention will be enhanced, which is helpful with such problems as       cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient  hydration.
2. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction  projects.
3. Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4. Slip Resistance: It can prevent slipping problem between mortar and the base material in construction    project as a result of its thickening effect.
