What are Light-Curable Conformal Coatings?
Conformal coatings are protective layers applied to printed circuit boards (PCBs) to shield them from moisture, dust, chemicals, corrosion, and temperature fluctuations. Traditional coatings require heat or moisture to cure, which can be time-consuming.
Light-curable conformal coatings use ultraviolet (UV) light, visible light, or LED curing processes to achieve instant hardening, making them highly efficient for high-volume production.
Key benefits include:
- Rapid curing within seconds to minutes
- Enhanced protection against moisture and corrosion
- Environmentally friendly with low or no VOC emissions
- High transparency for optical and LED applications
- Precise application with minimal waste
Competitive Landscape
The market is highly competitive and innovation-driven, with companies investing in advanced curing technologies and eco-friendly solutions. Key players include:
