Applications
1 )Binder and adhesive
As a water-soluble polymer, PVA has excellent adhesion, oil resistance, high film strength, good stability, if used in combination with the filler, can increase the initial adhesion and drying speed.
It is a thermoplastic adhesive derived from vinyl acetate monomer polymerization initiated at room temperature, ensuring a fast cure and yielding a durable, tough bonding layer resistant to aging. Commonly known as white latex or PVAC emulsion, it serves as an environmentally friendly water-based adhesive.
PVA can also be used.
