Permabond UV006830050B0101, UV683 UV-Curable Adhesive, 50ml Bottle, Case of 10
Permabond UV683 is a UV-curable acrylate developed for coating and doming applications, with viscosity suited to encapsulation of electronic components. It cures to an optically clear, tack-free finish and is suitable for coating smart card microchips. SKU UV006830050B0101 supplies ten 50 mL bottles per case.
Best Uses / Applications
Choose UV683 for professional doming, electronic encapsulation and smart card microchip coating where suitable UV light can reach the material. Its 1,000–1,600 cP viscosity distinguishes it from lower-viscosity UV681. Permabond also identifies UV683 in its phenolic-material application guidance, subject to light access and suitability testing. For PCB assemblies, review electrical properties, thermal performance, non-corrosive behavior and flame requirements with an adhesive specialist rather than assuming universal qualification.
Key Features
- Cure on demand with suitable UV equipment.
- Viscosity formulated for doming and electronic encapsulation.
- Optically clear, tack-free cured formulation.
- Fast curing with low-power lamps under TDS test conditions.
- 100% solids with no solvents.
- Resistance to brief high-temperature processes such as wave soldering, provided the joint is not unduly stressed.

Fixture Time vs. Tack-Free Time
| TDS lamp condition | Typical fixture time | Typical tack-free time |
|---|---|---|
| Low-power 4 mW/cm² battery lamp | 7 seconds | 15 seconds |
| LED 100 mW/cm² lamp | 2 seconds | 5 seconds |
| UV light guide, 30 W/cm² | 1 second | 1–2 seconds |
These examples are not universal cure guarantees. Actual cure depends on lamp power, spectral output, distance and substrate transmission. Match the LED peak wavelength to the adhesive with manufacturer guidance, and validate exposure for the actual geometry and thickness. Fixture time and a tack-free surface are distinct endpoints.
Application and Surface Preparation
Use clean, dry, grease-free surfaces. Remove silicone-based cleaning residues. Some metals, including aluminium, copper and its alloys, benefit from light abrasion to remove oxide. Isopropanol can degrease many surfaces; test thermoplastic compatibility and consider mold-release contamination.
Dispense directly from the bottle or use automated equipment for controlled dosing. Minimize exposure to ambient light and avoid entrapped air. Hold parts firmly without movement during cure and expose the joint to appropriate UV light for a validated duration. Do not assume cure in shadowed or opaque areas. The product is not recommended in contact with strong oxidizing materials; consult the SDS before handling.

Frequently Asked Questions
How much material does this listing include?
This listing supplies ten 50 mL bottles of UV683, SKU UV006830050B0101.
How does UV683 differ from UV681?
UV683 has a viscosity of 1,000–1,600 cP compared with 80–120 cP for UV681. The manufacturer emphasizes UV683 for doming and encapsulation, while UV681 is a lower-viscosity coating option.
Is UV683 suitable for smart card microchips?
Yes. The manufacturer specifically identifies its optically clear, tack-free formulation for coating smart card microchips.
Can it be used with phenolic materials?
Permabond identifies UV683 in its phenolic guidance where curing light can reach the material. Review the assembly requirements and test the specific substrate and process.
Will any UV LED lamp cure it?
Do not assume universal compatibility. The TDS lists 320–420 nm and recommends confirming that the LED peak wavelength matches the adhesive's photoinitiator.
Does the two-second fixture time mean full cure in every application?
No. It is a typical fixture time at the listed 100 mW/cm² LED condition; the listed tack-free time is five seconds. Validate the complete exposure process for your application.
Can UV683 withstand wave soldering?
The TDS permits brief higher-temperature exposure such as wave soldering provided the joint is not unduly stressed. This does not establish an unrestricted continuous-temperature rating.
How should the bottles be stored?
Store the liquid at 2–7°C (35–45°F) and protect it from room lighting, following manufacturer and SDS instructions.
