With the wide array of hearing aid styles available, custom formulations are essential for precisely bonding their miniature components in confined areas. Many devices require adhesives that are flexible, heat resistant and durable. For these reasons, silicones are often demanded. Optical clarity or the ability to match a specific color is also important as portions of hearing aids are visible when worn behind the ear. UV curing systems are frequently chosen for assembling and repairing hearing aids because of their rapid cure schedules, outstanding mechanical properties and their superior electrical insulation properties.
