Medical device adhesive for plastics bonding 10 December 2020

MD® 1172-M-UR, from Dymax, 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.

Dymax says this new product may be of interest to 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. 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 (365Nm), the material fluoresces bright red, making it easy to see on plastics that naturally fluoresce blue in colour, like PVC. This ISO 10993-5 cytotoxicity approved product is ideally suited for rapid diagnostic applications, microfluidics, reservoir and transducer assembly, and medical potting applications.

The product is LED optimised to cure in seconds upon exposure to LED UV (365Nm) or broad spectrum light energy. By using this product 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.
