Polyvinyl alcohol powder (PVA) commonly used as additives for mortar,wall putty and tile adhesive, it can improve the water retention,and it can reduce the friction of mortar, thereby enhancing the work efficiency and quality, prevent plastering layer cracking, falling off, increase the strength of adhesion and smoothness.PVA is widely used powder materials in construction building. Powder can quickly disperse in water, improve the initial adhesion property of building materials. Mainly used in thin layer binder, flexible binder, thermal insulation wall binder and add joint agent, etc.
