what is hpmc ’s parameters: appearance: white powder. particle size: 98.0%min through 100mesh. charring temperature: 280-300 deg.c. bulk density: 0.25-0.70g/cm3(usually around 0.5g/cm3) real specific gravity: 1.26-1.31 browning temperature: 190-200 deg.c. surface tension (2% water solution):42-56 dyn/cm. 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. application: - tile adhesive - gypsum based skim coat - paste water resistant putty - dry-mixed plastering mortar - masonry mortar - joint filler
