Assist™Senior ChemistThe medical migration problem
Medical device assemblies carry the highest switching cost of any adhesive application: the incumbent is embedded in a validated process, a regulatory submission and often a biocompatibility file. That is precisely why single-source exposure on a medical adhesive is a risk item — and why the right way to address it is a qualified second source, not an unqualified cheaper product. Incure's programme is built to minimise what changes: candidates are matched to your existing viscosity window, fluorescence inspection and UV/LED cure source, so qualification effort concentrates on the adhesive itself.
Cyro-Weld™ UV medical adhesive candidates
Representative grades from the Incure database (viscosity in cP, service temperature in °C; fluorescing versions carry the F suffix):
| Incure grade | Viscosity (cP) | Colour | Service temp (°C) | Notable properties (database highlights) |
|---|---|---|---|---|
| Cyro-Weld™ 5480 / 5480F | 40–80 | Clear / clear fluorescing | −55 to 80 | Ultra-low-viscosity wicking; elongation > 500%; biocompatible; sterilizable |
| Cyro-Weld™ 5480FT | 5,700–11,400 | Clear fluorescing | −55 to 80 | Non-sag thixotropic gel; high impact resistance |
| Cyro-Weld™ 5463 / 5463F | 400–800 | Clear / clear fluorescing | −55 to 80 | ISO 10993-5 compliant; sterilisation-stable; high peel strength (F) |
| Cyro-Weld™ 5463FT / 5463FVT | 4,500–9,000 / 17,000–34,000 | Clear fluorescing | −55 to 80 | Self-levelling to non-sag; ISO 10993 compliant; sterilisation-resistant |
| Cyro-Weld™ 5002F | 300–600 | Clear fluorescing | −55 to 80 | ISO 10993-5 compliant; needle bonding; hermetic seal; sterilizable |
| Cyro-Weld™ 5004 / 5004F | 1,100–2,200 | Clear / clear fluorescing | −55 to 80 / −55 to 125 | Micro-lumen wicking; moisture barrier; impact absorption (F) |
| Cyro-Weld™ 5005 / 5005F | 3,400–6,800 | Clear / clear fluorescing | −55 to 125 | Exceptional elongation; high shock resistance; broad mixed adhesion |
| Cyro-Weld™ 5013 / 5013F / 5013FT | 750–1,500 / 850–1,700 / 12,000–24,000 | Clear / fluorescing | −55 to 80 | Ultra-fast cure; high tensile strength; easy dispensing |
Matching your process, not just your spec
- Fluorescence for inline inspection: most grades are offered with a built-in UV tracer (F versions), so existing vision/blacklight inspection stations remain valid.
- Viscosity families: the same chemistry in wicking, self-levelling, and thixotropic non-sag versions (T/VT suffixes) lets you match the incumbent's dispensing behaviour closely — or fix a dispensing problem you already have.
- Cure source: candidates are matched to your installed UV or LED equipment and cycle time during the engineering review.
- Sterilisation: grades noted sterilisation-stable in the database are confirmed against your specific method (EtO, gamma, autoclave) during qualification — Incure will state plainly what has and has not been verified for your process.
A qualification path built for medical change control
The qualification toolkit provides the migration checklist, comparison-report format and a sample protocol covering initial and aged bond strength, thermal cycling, humidity ageing, chemical immersion, peel/impact, cure-depth verification, fluorescence inspection, sterilisation testing and a production trial. Incure supports the documentation; your quality system owns the decision.
