Dymax Launches Medical Device Adhesive for Difficult-to-Bond Plastics Dymax launches MD® 1172-M-UR, a LED UV and broad-spectrum light-curable adhesive for medical device plastics bonding. The adhesive is designed 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 (LOC), and other point-of-care medical devices.

Soft and Moisture Resistant Adhesive


The adhesive is suitable for manufacturers involved with the design of COVID-19 rapid diagnostic applications. It also features Ultra-Red® fluorescing for high-speed automated quality inspection.

The adhesive is moisture resistant, soft and flexible with a durometer of A70, and has a viscosity of 1,100 cP for improved wetting. MD® 1172-M-UR is formulated with Dymax Ultra-Red® fluorescing technology for simple 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 ISO 10993-5 Cytotoxicity approved adhesive is ideal for rapid diagnostic applications, microfluidics, reservoir and transducer assembly, and medical potting applications.

The adhesive is LED optimized to cure in seconds upon exposure to LED UV (365 nm) or broad-spectrum light energy. By using MD® 1172-M-UR in conjunction with a Dymax LED light-curing system, optimal cure time can be achieved, providing users with significant advantages over conventional lamp-curing systems including cooler curing temperatures, more consistent cure results, and lower intensity degradation over time.
