Vinyl Acetate (CAS 108-05-4), also known as Vinyl Acetate Monomer, is a clear, colorless, flammable liquid monomer that serves as a primary building block for polyvinyl acetate and ethylene-vinyl acetate copolymers used in adhesives, latex paints and packaging films. It is provided in Industrial Grade at 99.9% Purity , stabilized with HQ or MEHQ inhibitors. It offers excellent Adhesive Properties and film-forming capabilities, making it indispensable for wood glues and packaging materials. VAM is highly reactive and easily copolymerizes with various monomers to produce resins with targeted flexibility and chemical resistance. Its role in Water-Based Emulsions is vital for the development of eco-friendly paints and textile finishes.
