Dymax MD® 215-CTH-LV-UR-SC is an LED-curable adhesive specially formulated for difficult-to-bond plastics such as Nylon 12, PEBA, PET, and TPU. It incorporates Encompass® technology, which combines See-Cure® (blue-to-colorless visual cure indicator) with Ultra-Red® fluorescing for post-cure inspection. This dual capability ensures accurate adhesive placement, easy visual cure confirmation, and reliable in-line quality control. It is solvent-free, cures in seconds under LED or UV light, and is fully compliant with RoHS Directive 2015/863/EU .
The adhesive is designed for next-generation catheter assemblies and related medical devices, including:
Balloon-to-lumen bonding
Hub-to-lumen bonding
Marker band attachment
Manifold bonding
