Medical Device Bonding/Coating

Light curable medical device adhesives from Tangent Industries possess the reliability demanded by this market. Formulated to meet the most stringent standards of USP Class VI and ISO 10993 biocompatibility, Tangent medical device assembly adhesives deliver consistent high performance. These single component formulations are solvent-free, and fully cure (harden) in seconds when exposed to Ultraviolet (UV) or UV/Visible light energy. They are compatible with gamma, EtO, peroxide plasma, and E-Beam sterilization processes.

Medical device assembly can involve an incredibly broad array of applications. For this reason, Tangent offers an adhesive selection with a wide range of performance parameters and cured properties. Custom adhesive development is always an option with Tangent in order to satisfy unique performance requirements and component configurations.

Tangent medical device assembly adhesives bond with materials traditionally used by device manufacturers, as well as many of the most recent introductions from polymer manufacturers. These include various grades of polycarbonate, acrylic, polyurethane, ABS, PVC, polyethylene, polyimide, stainless steel, and glass. They can be used in applications relating to reservoirs, transducers, blood collection and drug delivery systems, surgical instruments, diagnostic equipment, breathing circuits, ophthalmic devices, and catheters.

As part of the medical device adhesive selection, Tangent offers its LEDcure adhesives. LEDcure adhesives fully cure under low intensity visible light in fractions of a second. They are ideal for use with LED light curing equipment. The adhesive surfaces cure dry and tack-free, including those which possess the greatest elongation and flexibility.

Please contact Tangent to confirm your product selection and to secure additional application assistance, including samples and process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include development of adhesive specifically tailored to the complexity of your application.
