Assist™Senior ChemistWhy customers ask for a DELO® alternative
DELO's light-curing and epoxy adhesives are common in electronics, camera modules, sensors, smart cards, optics and medical assembly. Enquiries to Incure are usually about supply strategy rather than performance: qualifying a second source on a high-volume line, reducing dependence on any single supplier, shortening lead times for Asian and American plants, and easing minimum-order and price pressure. Incure's dual-region manufacturing (USA and Singapore) and 458 UV/epoxy formulations make it a practical second-source candidate for many — not all — DELO® applications; the engineering review states honestly where a match is and is not available.
Application-category mapping
| If your DELO® adhesive is used for… | Incure candidate family | Representative grades (Incure database values) |
|---|---|---|
| Light-curing acrylate bonding of plastics, glass and metal | Cyro-Weld™ / Uni-Weld™ UV bonders | 1910 — 30–60 cP, −55 to 150 °C, high shear · 2463 — 450–900 cP · 2813 — 2,700–5,400 cP structural; viscosities to >1,000,000 cP |
| Medical device assembly (ISO 10993 requirements) | Cyro-Weld™ UV medical adhesives | 5002F — 300–600 cP fluorescing, ISO 10993-5 compliant · 5463 — 400–800 cP sterilisation-stable · 5480F — 40–80 cP wicking |
| Optical bonding, lens and sensor assembly | Optik™ UV optical adhesives | 7232 — 250–500 cP, −55 to 125 °C · 7648 — index-matched, low outgassing, stress-free |
| Structural epoxy bonding and potting | Epo-Weld™ epoxy systems (133 grades) | High-strength structural, thermally conductive (e.g. HTE-5350 aluminium-filled), optical-clear (HTE-5351) and flexible (HTE-5354) epoxies |
| Conformal coating and component protection | Ultra-Illumina™ UV conformal coatings | 3511 — 100–200 cP fluorescing · 3552 — 300–600 cP dual heat-cure · 5454F — 11,000–22,000 cP vertical potting |
Process compatibility first
- Cure source: candidates matched to your installed UV or LED equipment and cycle time — no lamp change required.
- Viscosity & rheology: wicking to non-sag gel, with custom viscosity available for jetting or fine-needle dispensing windows.
- Fluorescence: F-suffix versions for automated optical inspection.
- Dual cure: UV + heat capable grades (e.g. Ultra-Illumina™ 3552) where shadowed geometry needs a secondary cure.
How the evaluation works
The seven-step conversion process applies: submit the DELO® product number and application details, receive the closest candidates with database values and budgetary pricing, evaluate with samples at recommended settings, and qualify on your own evidence with the documented comparison. Incumbent values come from DELO's current published data — never estimated.

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 DELO Industrie Klebstoffe product. Candidate suitability is always subject to application validation on your parts and process.
