PVA is mainly used in various building materials such as dry-mix mortar and gypsum products. It can effectively increase the adhesion of cement, lime calcium and gypsum, improve the workability, slow down the drying time of the finished product surface, and prevent the surface coating cracking. It is suitable for interior wall decoration and tile bonding.
