NOTE: Most Covestro coatings are formulated for use with microwave lamps. Typically, a “D” and/or “H” bulb is used so the peak irradiance is at 365nm, but the overall wavelengths are from microwaves lamps, so they are broad. The intensity at the focal point is not something that can be easily measured. The cure will partially be determined by the time as well as the intensity.
