Hydrophilic Adhesives and Coatings

AR’s proprietary ARflow® adhesive technologies reduce the surface tension of aqueous 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:

•    Fast and stable capillary fills
•    Proven compatibility with biosensors
•    Non-interfering with test results
•    Visible clarity for verification of fluid movement
•    PSAs and heat seals demonstrates strong bonding to plastics
•    Coatings bond easily to PSA spacer tapes
•    Tailorable hydrophilic properties to regulate capillary fill time
•    Customizable product construction including thickness, choice of substrate and release liner
•    Printable lid stock
•    Clean die-cuts improve manufacturing efficiencies and capillary performance

Applications:

• Spacers to join plastic pieces, form capillary channels and move fluids from an entrance to a detection zone
• Assemblies of in-vitro diagnostic devices and related membrane-based immunoassays
