Chemical Properties ZHUOJUN® PVA can be regarded as a linear macro-molecular polymer with a secondary hydroxyl group. The hydroxyl group in the molecular of the PVA powder has high activity and can carry out typical chemical reactions of low alcohols, such as esterification, etherification, acetalization, etc., and can also react with a variety of inorganic or organic compounds. Typical Applications: - various construction mortar - dry powder render/putty - tile adhesive - gypsum spray plaster binder ZHUOJUN® PVA Advantages: -Improves bonding strength -Improves smoothness and surface gloss -Improves oil resistance and abrasion resistance -Improve film forming properties and chemical stability Technical Data Model No. PVA2488-01A Degree of Polymerization 1750±50 Saponification Value (mol %) 86.5-88.5 Viscosity (mPa's) 45.0-55.0 Volatile Matter (%) â?¤5.0 Sodium Acetate Content (%) â?¤1.5 pH Value 5-7 Particle Size (μm) 120-180 Application Various Construction Mortarï¼?Dry Powder Renders and Tile Adhesiveï¼?Gypsum Spray Plaster Binder; Suitable for wall, ceiling finishes and tile fittings Packaging A.Standard packed in 25 KG per paper plastic composite bag B.Big bags or other special packages are possible on request Weight/20' container: approx. 16 metric tons with pallets, approx. 18 metric tons without pallets Storage Stored in its original packaging in a dry and place with temperature below 30 Warranty It is recommended to use ZHUOJUN® PVA powders within 6 months.
