Water-based acrylic pressure-sensitive adhesives

Product information

Product outline

  • Environment-friendly emulsion without organic solvents.
  • A wide range of adhesive performance is materialized by our water-based polymerization technology.
  • Removability can be imparted by adding a crosslinker. (Epoxy, Carbodiimide etc.)
  • There are also improved samples for water resistance which is a common weakness of water-based PSAs (pressure-sensitive adhesives).
  • Please contact us if considering switching PSAs from solvent based to water-borne.

Grade comparison chart

Characteristics

AQUATRAN™ has greatly improved water resistance compared to conventional water-borne PSAs.
Transparency and adhesiveness are retained even if getting wet.

  • AQUATRAN™ can be applied to wet surfaces.
  • Suggested applications are for outdoors, window film, and for wet area.
