Copolymer Emulsion (VAE, VAA)

Compared to PVAc homo-polymers, vinyl acetate copolymer emulsions offer the advantage of being able to bond difficult-to-bond substrates such as plastic films, coated papers, and metal surfaces. Vinyl acetate copolymer emulsions are internally flexibilized with a comonomer such as ethylene (VAE) or an acrylate (VAA). The increased polymer flexibility provides for increased polymer mobility and, therefore, better adhesion.

Applications for PVAc copolymers include:

• Textiles
• Construction
• Packaging
• Graphic Arts
