On a high-volume disposable line, the bonding station cannot be the bottleneck. If fixture time runs longer than takt time, parts stack up or the conveyor stops. Incure Cyro-Weld™ CM-15 is an ultra-low-viscosity, fast-fixturing cyanoacrylate built to keep bonding off the critical path in external and disposable device assembly.
Cycle Time Is the Specification
A disposable molded assembly might have a two- to four-second station budget. Within that window the adhesive has to be dispensed, the parts mated, and handling strength reached so the part can index to the next operation. CM-15 fixtures in seconds on most plastics at normal shop humidity, which keeps it inside a tight budget without an accelerator on primed surfaces.
CM-15 is a single-component grade in the Cyro-Weld™ CM series. It is formulated to meet ISO 10993-5, ISO 10993-10, and ISO 10993-11 for biological safety, and is intended for external, disposable, and wearable components rather than implanted parts.
Incure Cyro-Weld™ CM-15 at a Glance
- Chemistry: single-component, room-temperature-cure cyanoacrylate
- Viscosity: ultra-low, for wicking into mated joints
- Fixture speed: seconds on most plastics; fastest of the low-viscosity CM grades in typical conditions
- Bond strength: up to roughly 3,900 psi on suitable substrates
- Biological safety: formulated to meet ISO 10993-5, ISO 10993-10, and ISO 10993-11
- Sterilization: compatible with validated ethylene oxide and gamma processes; confirm with Incure
Designing the Station Around the Adhesive
Fast fixture only helps if the rest of the station cooperates. Pre-position parts so mating happens immediately after dispense. Use a metered valve, not a hand applicator, so shot size is identical every cycle. Fixture the assembly under light, even pressure during the hold; point loads create thin and thick zones that cure at different rates. Keep shop humidity between 40 and 60 percent, because dry air is the single most common reason a fast grade suddenly runs slow.

Typical Applications
- Connector and hub bonding: locking press-fit fluid-path connectors on disposable sets
- Enclosure closure: sealing the seam on single-use handheld device bodies
- Filter and membrane frames: bonding frame halves that capture a filter medium
- Cartridge assembly: joining molded diagnostic cartridge components at line speed
Where a disposable joins two different plastics, thermal expansion across shipping and storage loads the bond line. Review how CTE mismatch causes adhesive bond failure during joint design, and use matching adhesive grade to substrate and mechanical demand as a framework for the selection.
Storage and Shelf Life
Refrigerate unopened CM-15 at 2–8°C and warm each bottle to room temperature before opening to prevent internal condensation. After opening, reseal tightly, keep headspace low, and use within the opened shelf life stated on the label. On a fast-fixture grade, an aged bottle that has absorbed moisture will fixture slower and less predictably, so first-in-first-out stock rotation is a real process control, not just housekeeping. Record lot numbers in the device history record and quarantine any bottle whose viscosity or dispense behavior has visibly changed.
Handling and Safety
Dispense in a ventilated station, use nitrile gloves and eye protection, and keep activator and water on hand to cure spills before cleanup. Do not transfer adhesive into secondary containers without full labeling.
Validation and Line Monitoring
Track fixture time as a process variable. A drift toward slower fixture usually means humidity has dropped or a substrate lot has changed; catching it early prevents a batch of under-cured joints reaching packaging. Incure supplies ISO 10993 test summaries and sterilization-compatibility data for your device file, but you own the finished-device evaluation and should test aged, sterilized bond strength on real production parts.

Frequently Asked Questions
Q: What makes CM-15 faster than other CM grades?
A: Its formulation is tuned for rapid fixture on common device plastics. Ultra-low viscosity also means a thin bond line that reaches strength quickly.
Q: Can we slow it down if it fixtures too fast?
A: Reduce shot size and keep humidity toward the lower end of the working range. Incure can also recommend a less aggressive grade.
Q: Does the extra ISO 10993 testing change how we use it?
A: The additional irritation and sensitization data broadens the documentation available for your risk file. Handling on the line is unchanged.
