By Richard W. Baird, senior chemical engineer and project manager, The Boeing Company Abstract We are assessing the feasibility of developing and implementing a heat-resistant, UV-curable clear paint, or clearcoat, for use on the aircraft exterior. The clearcoat would protect underlying paint from discoloration experienced in service, thus improving its appearance and … [Read more...] about Heat-Resistant, UV-Curable Clearcoat for Aircraft Exteriors

Q&A: UV-Curing Technology
by R.W. Stowe, Director of Applications Engineering, Heraeus Noblelight America LLC Q. Is there a "quick and easy" way to estimate the UV exposure under a UV LED lamp? A. Yes. All manufacturers of UV LEDs packaged for UV curing provide a specification of the irradiance or peak irradiance under the lamp, and typically at specific distances from the lamp face … [Read more...] about Q&A: UV-Curing Technology
Raw Material Strategies for Food Packaging Compliance
By Susan E. Bailey, Ph.D., technical manager - North America, IGM Resins UV and EB formulations convert under radiation exposure from a liquid composition to a solid material. The compositions can be complex mixtures. Any components that do not react to incorporate into the polymer network are trapped within it; however, they have the potential to migrate from the coating with … [Read more...] about Raw Material Strategies for Food Packaging Compliance
