Product Application of Vinyl acetate CAS#108-05-4
Vinyl acetate is a high-activity polymerization monomer that delivers stable bonding performance and excellent film-forming properties in emulsion systems. It is typically used in formulation polymerization ratios ranging from 10% to 60%, with its polymer stability and adhesive strength depending on polymerization temperature and formula proportion.
In industrial applications, vinyl acetate can be used as a core raw material for manufacturing emulsion adhesives, water-based coatings and polyvinyl alcohol resins. It may be produced through industrial ethylene oxidation and acetic acid addition synthetic processes.
