Polyvinyl alcohol PVA powder

Polyvinyl alcohol is an excellent water-based adhesive. The general product is flake, granular or flocculent. It is not easily soluble in cold water. Heating is generally required during dissolution. After being finely pulverized and surface treated, it has better cold water dissolving performance. But because of its thermoplasticity, pulvelow temperature cooling process to ensure that the powder of the crushed material is uniform. So that the material has excellent water solubility. Feature: Good film formation, adhesion, solvent resistance, friction resistance and tensile strength. Appearance:White solid powder Melting point:180-190ºC Size:80-120 mesh Application: Mortar, putty powder, coating, interface agent, decorative plaster, tile jointing agent, silicon nitride and other industrial ceramic powder bonding, cement, gypsum additives, etc. Advantage: Better temperature stability Extended Open Time Slip Resistance Sag Resistance Delayed Hydration Improved Workability Dosage-saving Benefit with Blanced Strength & Water Retention Increased Adhension Strength
