UV Curable - Illumabond. Repairing Leaks – This light-activated resin is used as a sealant or UV resin glue in cracks or leaks. That would be about 5 watts of light output. The translucent epoxy resin cures allegedly at 405nm. 3D Printing – The UV resins are more commonly used than you can think. UV casting of parts takes into consideration many things; amount (mass) of resin to be cured, ambient temperature and surface contour of the part you want the resin to cure around. A test in the laboratory has shown that about 20% of the light is emitted in 405nm. Excellent characteristics of UV-curing resins. Unlike 2-part epoxy resins, this UV cure resin requires no long setup times prior to hardening, and you use just the amount you need without waste. This kind of epoxy needs to be applied in thinner layers and with some care, but the ability to instantly dry your resin is worth it. Even fluorescent indoor light can cause it to change. The geckos were 12h in the light and still they were a bit sticky (of course, only the gluing of the magnet). UV-resins are sensitive to light, which can be easily controlled in a factory setting. I used 25 watt UV LEDs. SUPERB QUALITY - Transparent UV epoxy resin with self-leveling and self-degassing properties can cure smooth crystal clear, glassy finish. Epoxy resin is just as commonly used as polyester for the binding resin in fiberglass work but because epoxy is more expensive this applies more to industrial applications. When UV light hits a resin coating, it degrades the epoxy polymers, … Clean up with rubbing alcohol. Four in the list above are UV resins and I’ve marked them UV.
