Dymax said today that it has launched an LED UV and broad-spectrum light-curable adhesive for bonding COC/COP film laminates and other difficult-to-bond-to plastics used in the assembly of in vitro diagnostics (IVD), lab-on-a-chip and other point-of-care medical devices.
The product, MD1172-M-UR, may also be of interest to manufacturers involved with the design of COVID-19 rapid diagnostic applications, according to Torrington, Conn.-based Dymax.
The adhesive is moisture-resistant, soft and flexible with a durometer of A70, and has a viscosity of 1,100 cP for improved wetting. It is formulated with Dymax Ultra-Red fluorescing technology to ease visual post-cure quality inspection of the bond line area. After cure, when exposed to low-intensity black light (365 nm), the material fluoresces bright red, making it easy to see on plastics that naturally fluoresce blue in color, like PVC, the company said in a news release.
This ISO 10993-5 Cytotoxicity approved product may be suited for rapid diagnostic applications, microfluidics, reservoir and transducer assembly and medical potting applications. It is LED-optimized to cure in seconds upon exposure to LED UV (365 nm) or broad-spectrum light energy.
