Polyvinyl Acetate Emulsion

1."KURARAY POVAL" for emulsion
"KURARAY POVAL" is widely used for emulsion polymerization of vinyl acetate monomer (VAM) or VAM/acrylics as protective colloid or thickener.
PVAs have;
  1. Superior film strength Adhesive strength
  2. Water soluble polymer
  3. Surface activity
  4. Protective colloidability
