Vinyl acetate-vinyl alcohol copolymer

Vinyl acetate-vinyl alcohol copolymer (CAS 25213-24-5) is a partially hydrolyzed polyvinyl acetate that bridges the performance gap between fully hydrolyzed polyvinyl alcohol and standard polyvinyl acetate resins.

Where is Vinyl acetate-vinyl alcohol copolymer used?

• Textile sizing: coats warp yarns to reduce breakage during high-speed weaving
• Paper and board: surface sizing agent and binder for printability, surface strength and ink holdout
• Construction adhesives and tile-setting: bond strength and open time control on porous substrates
• Packaging and printing: film-forming binder in water-based coatings and laminating adhesives
• By controlling the degree of hydrolysis, manufacturers can tune water solubility, adhesion strength and film flexibility.

Good to know: Buyers should confirm hydrolysis degree ranges with suppliers when substituting between grades.

Commercial specifications

• Degree of hydrolysis and viscosity grade define suitability for a given application.
• Solution grades at defined solid content levels.
