Mercury UV lamp with reflector

On a wood flooring coating line, you’re chasing two targets at once: a finish that stands up to deep scratches, and a surface that holds a stable, high gloss. Undercure leaves the topcoat soft and easy to mar. Too much heat focused on the board, and you get warping—plus wasted energy. The answer is controlled, high-intensity UV curing, built around a mercury UV lamp and a proper reflector setup. What actually matters under the hood We lean on high-pressure mercury vapor lamps, with the main output band at 365 nm and solid UV-A/UV-B coverage. That spectrum drives both surface cure and through-cure in thick, transparent coatings. At the substrate, we’re typically running 8–12 W/cm² peak irradiance, using a high-purity aluminum reflector with a dichroic coating to bounce usable UV back into the curing zone. The reflector geometry keeps the spectral distribution consistent across the full width of the line, so gloss doesn’t drift edge to edge. Output stays stable around 2,000–3,000 hours, and we match the lamp electrical parameters—voltage, current, and ignition method—to your existing ballast and shutter interface. Why this approach fits wood flooring finishing In flooring, you’re often curing a thick wear layer that has to cross-link fast and come out tack-free. The 365 nm signature, concentrated by the reflector, delivers the photon density needed to consume the photoinitiators and finish the polymer network before the line moves on. The payoff is a cured film that holds up in standard abrasion testing and keeps a uniform gloss profile. Energy use drops because the reflector cuts down on wasted UV and IR, and you can push line speed without sacrificing hardness. A few shop-floor realities These mercury lamps are sensitive to airflow and substrate temperature. Keep the substrate temperature in check so thin profiles don’t overheat, and keep the lamp and reflector clean—otherwise irradiance drifts. Also, make sure the hardware lines up with your curing module: reflector width, lamp length, and mounting hardware have to match your fixture. Expect a bit more ozone at startup unless the system includes ozone-control measures.
