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.
Hydroxypropyl Methyl Cellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic,detergent,paints,as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.We can provide the regular grade HPMC, we also can provide modified HPMC according to customer re
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 additive
