Assist™Senior ChemistWhy customers ask for a Tangent™ alternative
Tangent Industries light-curable adhesives are used in medical device and industrial assembly; the Tangent brand is now part of the Panacol / Hönle group. The enquiries Incure receives are supply-strategy driven: qualifying an independent second source on a validated device, adding an Asian supply point for lines in Singapore, Malaysia, Penang or China, widening the available viscosity and fluorescence options, or relieving pricing on high-volume assemblies. Because Incure manufactures the same chemistry class in both the United States and Singapore, one qualified Incure formulation can serve as a dual-region second source.

|---|---|---|
| Needle and cannula bonding | Cyro-Weld™ UV medical adhesives | 5002F — 300–600 cP, clear fluorescing, ISO 10993-5 compliant, hermetic seal, sterilizable · 5013F — 850–1,700 cP, ultra-fast cure |
| Catheter, lumen and reservoir assembly | Cyro-Weld™ UV medical adhesives | 5480 / 5480F — 40–80 cP wicking, elongation >500%, biocompatible · 5004 — 1,100–2,200 cP micro-lumen wicking |
| Flexible / dissimilar-substrate joints (e.g. PC-to-TPE) | High-elongation Cyro-Weld™ grades | 5005 / 5005F — 3,400–6,800 cP, exceptional elongation, −55 to 125 °C — see the PC-to-TPE guide |
| General plastic, glass and metal bonding | Uni-Weld™ multi-substrate and glass & metal bonders | 1910 — 30–60 cP, −55 to 150 °C · 2463 — 450–900 cP · 2813 — 2,700–5,400 cP structural |

What Incure matches
- Viscosity window: wicking (40 cP) through non-sag gels (>34,000 cP), plus custom viscosity where your spec sits between standard grades.
- Fluorescence: F-suffix fluorescing versions keep existing blacklight/vision inspection valid.
- Cure response: matched to your installed UV or LED source and cycle time during the engineering review.
- Biocompatibility and sterilisation: ISO 10993-5 compliant and sterilisation-stable grades shortlisted first for medical work; your specific method is verified in qualification.
How the evaluation works
The seven-step conversion process applies: submit the Tangent™ product number and application details, Incure identifies the closest candidate, adjusts where necessary, supplies samples with recommended settings, and helps document the comparison for your change control. Incumbent values in every comparison come from the manufacturer's current published TDS — never estimated.
