FAQ Entries » UV Conformal Coatings

UV curable conformal coatings for PCBs and assemblies providing moisture, dust, chemical, and vibration protection with rapid cure under UV/LED.

What are Optimax® UV conformal coatings?

UV curable coatings applied to PCBs and assemblies for moisture, dust, chemical, and vibration protection. Unlike traditional coatings relying on thermal or moisture cure, UV conformal coatings harden in seconds under the correct spectrum and intensity of UV/visible light.

When should I use a UV conformal coating?

Where environmental protection is required without added weight or thickness, especially in automotive, aerospace, or industrial electronics.

How quickly do these coatings cure?

They cure rapidly under UV/LED, allowing immediate handling and inspection. Benefits include faster cycle times, reduced work-in-progress (WIP), smaller floor space for curing stations, and less energy consumption compared to thermal ovens.

Are they suitable for automated application?

Yes, compatible with spray, dip, or conveyor applications in high-volume lines.

Do they provide electrical insulation?

Yes, they offer excellent dielectric protection for sensitive electronics.
