realUV LED Lights for Curing Polymers
We manufacture magnesium dies and part of the process is exposing the plate which has a light-sensitive polymer coating currently we use a Thorium Iron Doped bulb. The optimum spectral wave is 386nm to cure the coating. We have experimented with UV LED light. On both tests, the UV LED was very close to 386nm.
The first test was a cluster very tight together and the size of the LED was 3228 if I recall. The closer the light the better it would cure. In the second test, the size was 3228 however they are spaced ½” apart. What we noticed was the exposure didn’t change much when closer to the plate. So I’m not sure if the LED lights need to be closer together or if we need different UV LED lights.
What I noticed on your website you refer to your strips as real UV LEDs. Are there different levels of strength of UV available in UV LED lights? If so what do you have to offer and what makes the difference?
Though we do not sell 386nm ultraviolet products, we have attached a link to an informational article below regarding the differences between the 365nm and 395nm ultraviolet products in our catalog, which we do hope proves to be helpful for your installation planning.
To summarize, the further the output is from the 400nm visible spectrum, the greater the ultraviolet effect is upon the target. As such, our customers most frequently purchase the 365nm option for curing processes to take advantage of the greater effect.
As a further note, you might be interested in our 365nm Ultraviolet Flex Panel for curing and other installations. Below is the product link.
We have also attached a link to the 365nm realUV™ LED Strip Lights ultraviolet irradiance pattern below, which charts the microwatts output per square centimeter (μW/cm2).
