Permabond UV006830001L0101, UV683 UV-Curable Adhesive, 1 Liter Bottle
Permabond UV006830001L0101, UV683 UV-Curable Adhesive, 1 Liter Bottle
Permabond UV683 is a UV-curable acrylate developed for coating and doming, with viscosity suited to electronic component encapsulation. Its optically clear, tack-free formulation is also suitable for coating smart card microchips. SKU UV006830001L0101 supplies one 1 liter bottle, not a case of smaller bottles.
Best Uses / Applications
Use UV683 for professional doming, electronic encapsulation and smart card microchip coating where suitable curing light can reach the material. The single 1 L package supports larger coating runs and controlled dispensing. Its 1,000–1,600 cP viscosity distinguishes it from lower-viscosity UV681. Permabond also identifies UV683 in its phenolic-material guidance, subject to light access and application testing. For PCB assemblies, review electrical properties, thermal performance, non-corrosive behavior and flame requirements with an adhesive specialist.
Key Features
- Cure on demand with suitable UV equipment.
- Viscosity suited to doming and electronic encapsulation.
- Optically clear, tack-free finish.
- Fast curing with low-power lamps under TDS test conditions.
- 100% solids, no solvents.
- Manufacturer-described resistance to brief high-temperature processes, including 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. Cure depends on lamp power, spectral output, distance and substrate transmission. Match LED peak wavelength with manufacturer guidance and validate exposure for the actual geometry and thickness. Fixture time and a tack-free surface are different endpoints.
Application and Surface Preparation
Use clean, dry, grease-free surfaces and 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 ambient-light exposure and entrapped air. Hold parts firmly without movement during cure and expose the joint to suitable UV light for a validated duration. Do not assume cure in shadowed or opaque areas. UV683 is not recommended in contact with strong oxidizing materials. Read the SDS before handling.
Grade and Package Comparison
| Option | Selection guidance |
|---|---|
| UV683, this 1 L bottle | One larger bottle of the doming and encapsulation grade; viscosity 1,000–1,600 cP at 25°C. |
| UV683, 50 mL bottles | Same UV683 grade in smaller bottles; separate listing supplies a case of ten. |
| UV681 | Lower-viscosity coating grade, 80–120 cP; typical tensile strength 10–12 N/mm² versus 12–14 N/mm² for UV683. |
| Phenolic assemblies | Verify light access and application-specific electrical, thermal, non-corrosive and flame requirements. |
Frequently Asked Questions
Is this a single bottle?
Yes. SKU UV006830001L0101 supplies one 1 liter bottle of UV683.
Is it the same formulation as UV683 in 50 mL bottles?
Yes. Both listings are the UV683 grade, covered by the same grade TDS. Package size and sales quantity differ.
How does it differ from UV681?
UV683 has a viscosity of 1,000–1,600 cP and is emphasized for doming and encapsulation. UV681 is a lower-viscosity coating grade at 80–120 cP.
Can I coat smart card microchips or phenolic components?
Permabond identifies smart card microchip coating and discusses UV683 in its phenolic guidance. Ensure curing light can reach the material and validate suitability on the actual assembly.
Will any UV LED lamp work?
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 LED example guarantee full cure?
No. Two seconds is a typical fixture time at the stated 100 mW/cm² condition; the listed tack-free time is five seconds. Validate your full exposure process.
Can UV683 withstand wave soldering?
The TDS describes brief higher-temperature exposure provided the joint is not unduly stressed. This is not an unrestricted continuous-temperature rating.
How should the 1 L bottle be stored?
Store the liquid at 2–7°C (35–45°F), protected from room lighting, following manufacturer and SDS instructions.
