SOKALAN VA 64 P

SOKALAN VA 64 P is a vinylpyrrolidone/vinyl acetate copolymer. It is typically supplied as a powder. The "64" in its name refers to the ratio of the monomers, indicating a 60% vinylpyrrolidone and 40% vinyl acetate composition. It's a linear random copolymer of N-vinylpyrrolidone (VP) and vinyl acetate (VA). It is readily soluble in water and many organic solvents like ethanol, isopropanol, and methylene chloride. It acts as an excellent film-forming agent, creating transparent, flexible films. Adhesive and Binding Properties: SOKALAN VA 64 P exhibits good adhesive properties, making it an effective binder. Dispersant and Crystal Growth Inhibitor: It can function as a dispersant, helping to stabilize suspensions and prevent particle aggregation. It is particularly noted for its ability to inhibit crystal growth and nucleation in various formulations. Like many PVP-based polymers, it is hygroscopic, meaning it absorbs moisture from the air.
