Panacol-USA offers light curable medical device adhesive products that address the challenges of hearing aid assembly and their operating environments. Tangent’s selection of adhesives includes our exclusive LEDcure light curable adhesives. LEDcure adhesives will fully cure under low intensity UV or visible light in seconds. They are ideal for use with LED light curing equipment. The ability to cure with low intensity light makes these adhesives particularly well suited for applications involving pigmented substrates. Typical applications include faceplate/shell bonding, as well as attaching receiver tubes to the shell.
LEDcure adhesives are extremely clear in appearance. They offer cured properties from hard/rigid to soft/flexible. Cured surfaces are smooth and tack-free, including products with the greatest elongation and flexibility.
View the hearing aid/audiology device assembly adhesives listed below for a possible candidate for your application. 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.
