           Substrates

           Bond gaps
            •       0.002-0.006 inch gap preferred, typical
            •       0.001-0.003 inch gap preferred, needle/hub

           UV Curing Systems

           Required Approvals

                                      Typical Substrates

             PVC - strong bonds achievable. Caution with highly
              plasticized PVC
             PC, PS, ABS, PUR - strong bonds achievable
             TPE, SEBS, Pebax - selective adhesives
             Silicone - requires surface treatment

                         UV Curing Considerations

           Oxygen Inhibition - The phenomenon where some
            adhesives have a wet film on the surface after cure
            •       Oxygen interferes/slows down the cure on the outermost
                    surface of the adhesive leaving the surface semi/uncured.
            •       Techniques to overcome:
                    • Higher intensity and/or longer UV exposure
                    • Remove oxygen from bond line
                        • Interfacial bond
                        • Inert gas blanket (nitrogen)
            •       Try a new adhesive

              UV Curing Considerations cont.

           Pulse curing
            • Not recommended for Dymax adhesives
            • Typically results in a tacky surface or not optimal
               cured properties
           LED vs. Broad spectrum (UVA/BlueVis output)
            • Identify LED wavelength output – UVA or VIS?
            • Match output of the UV equipment with absorption
               of the adhesive

                                      Required Approvals
