New flexible light curing adhesives for medical devices

Dymax MD medical device adhesive 1072-M from Intertronics is a UV and visible light curing adhesive particularly suited to rapid bonding of cyclic olefin polymers/copolymers (COP/COC) which have become popular choices in the point-of-care device industry because of their many advantages, including high strength, hardness, low water absorption and excellent biocompatibility.

Dymax 1072-M MD adhesive is a UV/broad-spectrum-cured adhesive specifically designed for bonding COC/COP film laminates and other difficult-to-bond-to polymers, but is also said to be excellently suited to a variety of other plastics widely used in the manufacture of medical devices. Typical applications include needle assembly, reservoir assembly, transducer assembly and medical potting. Other bondable substrates include stainless steel, PS, PU, PVC, ABS, EVA, PA, PC, PCTG, PEBA, PET, PETG, PI, PMMA, PSU, SAN, TPU, CER, AL and glass.

Optimised for LED curing lamps, 1072-M will cure in less than three seconds after exposure to LED or broad-spectrum UV light, enabling fast processing, greater output and lower production costs. It is soft and flexible with a durometer of A58. It has a viscosity of 1,000 cP for improved wetting, making it ideally suited for interfacial bonding requirements. The product is ISO 10993-5 cytotoxicity approved.
