Dymax MD® 1405-M-UR-SC is an LED-optimized, medical-grade adhesive formulated with Encompass® technology, which uniquely integrates See-Cure® (blue-to-colorless transition) and Ultra-Red® fluorescing capabilities. This dual system allows for both visual confirmation of adhesive placement and post-cure bond-line inspection, ensuring robust process validation. Designed for 385 nm and 405 nm LED curing systems, the adhesive provides rapid, deep-section curing while maintaining biocompatibility. It contains no nonreactive solvents and complies fully with RoHS Directive 2015/863/EU.
The product is engineered for critical medical device assemblies, particularly where verification of adhesive placement and reliability of cure are essential. Key uses include:
Syringes
Blood transfer devices
Winged infusion sets
Collection sets
Dialyzers
Combination devices
