VAE – the basis of waterbased adhesive polymers

Vinyl acetate-ethylene (VAE) technology offers outstanding benefits in terms of performance, safety and versatility. VAE dispersions are waterbased co- and terpolymers mainly based on vinyl acetate and ethylene as comonomers.

Ethylene contributes permanent flexibility
to the VAE polymer. No external plasticizer
is thus necessary in VAEs.

What is the VAE polymer?

VAE Copolymer and Terpolymer Dispersion Properties:

  • VAE dispersions can be formulated into adhesives that provide outstanding benefits:
  • Excellent adhesion to a wide variety of substrates
  • High heat resistance
  • Very fast setting
  • Excellent machinability and re-emulsification properties
  • Very good cost / performance ratio
  • Tg range from approx. -35 °C to approx. 30 °C, depending on ethylene content

Applications examples

VAE dispersions can be formulated into adhesives for various applications:

  • Paper packaging (e.g. food packaging,
  • envelope manufacturing, film lamination onto paper)
  • Wood (e.g. film lamination onto wood,
  • 3D membrane pressing, EPI systems)
  • Flooring installation (e.g. textile flooring,
  • flexible coverings)
  • Car interiors (e.g. door paneling)
  • Tapes & labels

What properties does Ethylene contribute to VAE?

• Softness (Tg approx. -125 °C)
• Non-polar, hydrophobic
• Permanent flexibility
• High saponification resistance
• Form ideal copolymers with vinyl acetate

What properties does Vinyl Acetate (VAM) contribute to VAE?

  • Hardness (Tg approx. 32 °C)
  • Polar, hydrophilic
  • Rigid
