Assist™Senior ChemistHow to use this guide
Customers rarely change adhesives for price alone. The common triggers are single-source risk on a validated assembly, price escalation, MOQ and lead-time pressure, or a discontinued grade. Because Loctite® UV products span many chemistries and applications, the correct Incure candidate depends on what your grade actually does in your process. The mapping below matches application categories to Incure product families using Incure's published database values; the specific candidate is confirmed after an engineering review of your product number, substrates and cure equipment.
Application-category mapping
| If your Loctite® UV adhesive is used for… | Incure candidate family | Representative grades (Incure database values) |
|---|---|---|
| Medical device bonding (needles, catheters, reservoirs; ISO 10993 requirements) | Cyro-Weld™ UV medical adhesives | 5002F — 300–600 cP, clear fluorescing, ISO 10993-5 compliant, sterilizable · 5463 — 400–800 cP, sterilisation-stable · 5480F — 40–80 cP wicking, biocompatible |
| Plastic-to-plastic and multi-substrate bonding | Cyro-Weld™ / Uni-Weld™ multi-substrate bonders | Grades from 40 cP wicking to >1,000,000 cP non-sag gel; fluorescing and non-fluorescing versions |
| Glass-to-metal and glass-to-glass structural bonding | Uni-Weld™ UV glass & metal bonders | 1910 — 30–60 cP, −55 to 150 °C, high shear strength, crystal-clear · 2463 — 450–900 cP, high impact resistance · 2813 — 2,700–5,400 cP structural |
| Optical assembly and lens bonding | Optik™ UV optical adhesives | 7232 — 250–500 cP, −55 to 125 °C · 7223 / 7254 — 1,200–2,400 cP · 7648 — index-matched, low outgassing, stress-free |
| PCB conformal coating | Ultra-Illumina™ UV conformal coatings | 3511 — 100–200 cP fluorescing · 3552 — 300–600 cP, dual heat-cure capable · 5454F — 11,000–22,000 cP vertical potting gel |
| Form-in-place gaskets and sealing | Uni-Seal™ UV gaskets / sealants | Flexible sealing grades; fluorescing options for inline inspection |
| Temporary masking for plating, sandblasting, wave solder | Litemask™ UV peelable maskants | Peelable UV maskants engineered for clean removal |
What about a specific product number, like Loctite® 3311?
Individual product numbers deserve individual answers. If you use a specific grade — for example a light-cure medical adhesive such as Loctite® 3311, or any AA, 3xxx or 5xxx series UV product — submit the product number with your substrates and cure equipment. Incure responds with the closest candidate, a side-by-side of the incumbent's published TDS values against measured Incure values, and a recommended evaluation protocol. Incure does not publish speculative spec-for-spec tables for competitor grades; comparisons are built from the manufacturer's current published data at the time of your enquiry, so your change-control file starts accurate.
Why engineers shortlist Incure as the second source
- Breadth without requalifying the process: 325 UV/LED grades means the viscosity, fluorescence and cure profile you already run is usually available off the shelf — and can be custom-tuned when it is not.
- Dual-region manufacturing: the same formulation supplied from the USA and Singapore, which is itself a second-source argument beyond any one product.
- Transparent budgetary pricing: pack sizes, MOQs and indicative USD pricing for every grade are published in the INCURE Assist™ portal.
- Documented, honest comparison: the standard report states differences and outstanding validation work explicitly — the format is in the qualification toolkit.
Typical evaluation path
The seven-step conversion process applies: product-number review → candidate selection → viscosity/fluorescence/cure matching → samples with recommended settings → laboratory and line trials → comparison report → qualification as alternate or primary source. Most customers keep the incumbent approved and add Incure as the qualified second source first; volume allocation follows the evidence.

Incure figures are database values for the referenced Incure grades (viscosity in cP, temperature in °C); they are not measurements of, or claims about, any Henkel product. Candidate suitability is always subject to application validation on your parts and process.
