The development of high power short wavelength light emitting diodes (LED) in the late 90s created the potential of a solid state UV curing source. The benefits of LEDs are low heat, portability and low power consumption. These advantages are particularly attractive for the curing of various adhesives, inks, and coatings in applications where dimensional stability of the substrates is required. In this work, the effect of inert atmospheres, use of photosensitizer, light intensity, and colour on the curing behavior and surface properties of UV-LED curable colour coating systems were investigated by photo-DSC, FT-IR/ATR, and stain resistance. The results showed that the polymerization reactivity and the conversion for the system with ITX and in inert gases were higher than the corresponding values for the systems without ITX and in air. |
