Vinyl Chloride-Vinyl Acetate Copolymer Applications

Inks and Coatings: Widely used as a binder in gravure and silk-screen printing inks due to its excellent adhesion to various substrates and high pigment compatibility.

Adhesives: Provides strong bonding properties in heat-sealable lacquers and solvent-based adhesives, particularly for aluminum foil and plastic films.

Surface Finishes: Acts as a protective coating for metal, wood, and paper, offering resistance to water, chemicals, and weathering.

Magnetic Media: Historically used in the production of magnetic tapes and cards as a durable binder for magnetic particles.

Plastic Processing: Employed as a processing aid or modifier in PVC formulations to improve flexibility and melt flow characteristics.

Strip Lacquers: Used in the formulation of peelable coatings for temporary surface protection during transport or manufacturing.
