UV Medical Adhesives — Cyro-Weld™
Biocompatible UV-curable adhesives engineered for the high-speed assembly of disposable medical devices. Replacing solvent welding and mechanical joining, Cyro-Weld™ formulations deliver instant hermetic seals on needle hubs, catheters, reservoirs, and tube sets — while meeting rigorous sterilization and biocompatibility requirements.
Technical Specifications
Built for Medical Device Assembly
Cyro-Weld™ UV medical adhesives are specified across device OEMs and contract
manufacturers wherever speed, biocompatibility, and sterilization resistance are critical.
Frequently Asked Questions
Common questions about Cyro-Weld™ UV medical adhesives for device assembly.
-
Yes. Cyro-Weld™ UV medical adhesives are ISO 10993-5 compliant for cytotoxicity, making them suitable for use in medical devices that contact patients. This compliance is the baseline biocompatibility requirement for disposable device assembly. Additional ISO 10993 tests for specific contact types and durations are available — contact our team with your device classification for guidance.
-
Yes. Cyro-Weld™ grades are formulated to survive ethylene oxide (EtO), gamma irradiation, and e-beam sterilization cycles used for disposable medical device sterilization. They maintain bond integrity and biocompatibility through multiple sterilization cycles, which is critical for needle hubs, catheter assemblies, and reservoir housings used in single-patient disposable devices.
-
Flexible grades within the Cyro-Weld™ range achieve up to 912% elongation at break, making them ideal for catheter assemblies and tube sets that experience repeated bending and kinking stresses. These high-elongation formulations replace solvent bonding to eliminate stress cracking while ensuring long-term hermeticity in fluid-path assemblies.
-
Cyro-Weld™ grades bond reliably to polycarbonate, polypropylene, nylon, ABS, stainless steel, and glass — the substrate combinations most common in disposable medical device construction. Pull-out strength on needle-to-hub (stainless to PC or PP) joints is a key performance metric validated in our product data sheets.
-
Fluorescing grades 5002F, 5002FT, 5002FVT, 5004F, 5005F, and 5013F are formulated with UV-fluorescent markers that allow 100% automated optical inspection of bond coverage on high-speed assembly lines. Under a UV inspection lamp, the cured adhesive glows, enabling machine-vision systems to verify complete fill of needle hubs and catheter joints without slowing throughput.
-
Most Cyro-Weld™ UV medical adhesive grades are optimised for cure at 365 nm, which is the primary output of conventional mercury UV spot and flood lamps. Some grades also respond to broader UV-A / UV-Vis spectra at 385–405 nm, making them compatible with UV LED curing systems. Refer to the technical data sheet for each grade or contact our team to match the grade to your existing lamp system.
