Polyvinyl acetate (PVA) liquid is a water-based synthetic polymer used mainly as an adhesive, binder, and film-former. It appears as a milky white emulsion and is commonly found in wood glue, paper adhesives, and paint formulations.
PVA offers strong adhesion to porous materials like wood, paper, and fabric, and it dries clear and flexible. It is non-toxic, easy to handle, and widely used in construction, packaging, textiles, and arts & crafts. However, it has limited water resistance unless modified with additives or crosslinkers.
