Characterizing the Efficiency of UV LED Curing

This paper examines the effects of some key operating parameters of UV sources on the curing of various UV inks, coatings and adhesives. The effects of peak UV wavelength and peak intensity are quantitatively evaluated using FT-IR. The data are helpful in guiding both formulators, raw material suppliers and end users to better understand the impact of the UV sources, especially UV LED sources, ...

UV-LED Curing Efficiency of Wood Coatings

Ultraviolet light emitting diodes (UV-LEDs) have attracted great interest in recent years. They can be used to polymerize coatings, such as those used for prefinished wood flooring. In this project, two lamps were compared for their suitability to be used on a wood flooring finishing line: a UV-microwave and a UV-LED lamp. Low heat emission was found for the UV-LED lamp compared to the UV-micro...

Advances in UV Curing for Medical Applications

Adhesion to tooth substrates and dental alloys by methacrylates having a naphthalic anhydride structure.

Three isomers of methacryloyloxyethyl naphthalenetricarboxylate anhydrides (MENTA-126, -236 and -184) were synthesized, and their adhesiveness to teeth and non-precious dental alloys was investigated. The MENTA resins initiated by TBB-O showed about 12-13MPa of the bond strength on treated enamel and 10-12.5MPa on treated dentin after 120 thermocycles, while, after the equal thermal cyclings, t...
