Product Description

Physical properties

Appearance: white free-flowing powder, odorless and tasteless.

Solubility: Polyvinyl alcohol powder (PVA) 17-88 and 24-88 type are partially alcoholy-soluble types which can be soluble in room temperature water. It is prohibited to use when the temperature drops to below 0 degree C; when the temperature is below 10 degrees C, sufficient dissolution time is required for dissolution, usually takes 5-10 minutes.

Solution stability: Aqueous solution of low viscosity Polyvinyl alcohol is stable at room temperature and does not deteriorate during storage.

Film Formability: Due to the high adhesion strength between Polyvinyl alcohol molecules, Polyvinyl alcohol is easy to form a film, which has colorless and transparent smooth surface with high mechanical strength and good solvent resistance.

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.
