PVA-2488
01
Polyvinyl alcohol powder is a kind of water-solu-ble environment-friendly polymer, which use liquid nitrogen as agent and crushed at low tem-perature.It has good film-forming, emulsifying and bonding properties. lt is especially good for building mortar additirves improving the flexibility water retention and viscosity of mortar. In addi-tion,it can reduce the friction of mortar,therefore enhancing the working efficiency and quality preventing the crack and falling off of plastering layer enhancng the adhesion strength and smoothness
