Dymax MD® 215-CTH-UR-SC is an LED-curable medical adhesive that incorporates Encompass® Technology, which integrates See-Cure® (blue-to-colorless visual cure indicator) and Ultra-Red® fluorescing features. This dual system enables both real-time visual confirmation of adhesive placement and reliable post-cure bond-line inspection. The product is specifically designed for difficult-to-bond plastics such as Nylon 12 and PEBA, making it particularly valuable in advanced catheter manufacturing. It is solvent-free, cures rapidly under LED/UV light, and is fully compliant with RoHS Directive 2015/863/EU .
The adhesive is engineered for next-generation catheter and medical device assemblies, including:
Balloon-to-lumen bonding
Hub-to-lumen bonding
Marker band attachment
Manifold bonding
General catheter assembly
