Curing UV Encapsulation & Potting Resins

Q: What wavelength cures uv encapsulation & potting resins?

UV Encapsulation & Potting Resins in this class commonly cure at 365 nm, 395 nm, 405 nm. Cure depth depends on wavelength, intensity, and the resin’s rating; deep pots are cured in layers or use a dual-cure (heat/moisture) mechanism for volume the light can’t reach. Confirm the exact band on your adhesive datasheet.

Q: Which UV system should I use for uv encapsulation & potting resins?

SunSpot 2. For depth you want penetration, the SunSpot 2’s broad spectrum and high intensity drive cure deeper into a thick film, and a high-flux guide plus splitter light the pot from several angles.

Resins that seal and protect components, cured as deep as the light penetrates, with dual-cure options for shadowed volume under parts.

How It Cures

Cure depth depends on wavelength, intensity, and the resin’s rating; deep pots are cured in layers or use a dual-cure (heat/moisture) mechanism for volume the light can’t reach.

Through a substrate: Cured into the pot from above and from multiple angles for shadowed volume.
