Frequently Asked Questions About ABChimie® 4002 UV
What are typical applications for ABChimie® 4002 UV?
ABChimie® 4002 UV is a UV-curable conformal coating designed to protect printed circuit board assemblies (PCBs) and components in demanding manufacturing environments, including:
- Automotive electronics (e.g., control units, sensors)
- Industrial automation (e.g., motor drives, PLCs)
- Consumer electronics (e.g., smart devices, wearables)
- Other high-reliability electronic assemblies
What is the recommended curing method for ABChimie® 4002 UV?
ABChimie® 4002 UV is UV-curable and should be cured with a mercury lamp. The minimum UVA dose is 1000 mJ/cm² for a 100 μm thickness. The mercury lamp-curable version is ABChimie® 4002 UV. Higher UVA doses do not negatively affect final properties.
