Redispersible polymer Powder was further modified by the method of spray drying adding other substances to polymer latex. As a kind of polymeric powder with redispersible, It can be made into aqueous emulsion dispersed in the water.
It improves the important application properties of dry mortars, like longer opening time, better adhesion with difficult substrates, lower water consumption, better abrasion and impact resistance.
This VAE RDP Re-Dispersible Polymer Powder Used in construction mortar and wall putty. In the construction, the dosage of VAE is very low ,6-12kg per ton of mortar, but an important additive , mproving flexibility and its elastic in Mortar.
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.
Introduction of Landcel HPMCThe alias of Hydroxypropyl methyl cellulose is hypromellose; cellulose hydroxypropyl methyl ether, English abbreviation: HPMC, It uses cotton cellulose as raw material, and is produced by special etherification under alkaline conditions , the whole process is completed un
Tile adhesives are cement and/or polymer dispersion-based systems. The rheological additives used for these are mainly cellulose ethers, which provide the right consistency for the application, sag resistance of wall tiles, water retention for the optimum hardening of cement, and the control of open
