Hydrophilic Adhesives and Coatings

Adhesives Research’s ARflow® proprietary hydrophilic adhesive technologies reduce the surface tension of fluids (water, urine or blood), allowing for rapid flow from the inlet area to a remote reagent site within diagnostic and microfluidic devices.  AR’s ARflow® hydrophilic surface technologies are available as pressure-sensitive adhesives (PSAs), heat-seals and coatings.

Benefits of this technology:

  • Compatible with sensitive chemistries
  • Demonstrates strong bonding to low-surface energy plastics
  • Tailorable hydrophilic properties to regulate capillary fill time
  • Readily customizable product construction including thickness, choice of substrate and release liner
  • Clean die-cuts improve manufacturing efficiencies and capillary performance

Applications:

  • Spacers
  • Lidding and covers
