Adhesives and Epoxies Q&A

  •   I would like to insert 72D Pebax extruded tubing into the inner diameter of a polycarbonate tube. What is the appropriate gap per side if I want to use Dymax 204 CTH UV-cure adhesive?

    The optimum gap size for UV bonding applications in general is 0.002 to 0.006 in. In catheter bonding applications in which a Pebax tube is bonded into a polycarbonate Y-connector, we often see bond gaps of around 0.1 mm per side. The Dymax 204-CTH-F family is a good choice for this type of application and substrate combination. Another product to consider is 208-CTH-F.
