WebMay 1, 2024 · The photo-curing technology [1] rapidly replaced a part of the traditional polymeric coatings because of energy-saving, environmental protection, high efficiency, and low or zero VOC etc [2]. However, the light irradiation was weakened at a thick depth according to the Beer-Lambert law. WebNov 1, 2004 · Acylphosphine oxides absorb UV light between 380 - 410 nm. In this range, titanium dioxide is transparent, which enables the photons to reach the photoinitiator at the bottom of the film. The anatase form of titanium dioxide is especially suitable for UV-curing systems. Thus, white-pigmented UV coatings can be formulated with good hiding power ... raw news headlines
Photoinitiator Selection - RadTech
WebA new approach for the cure-on-demand of coatings involves the photo-generation of a base catalyst, which then causes resins to crosslink and cure via a base-catalysed mechanism. The advantage of using a photolatent base catalyst is to be able to cure a wide range of conventional coatings at low temperatures. The influence of different parameters on the … WebModifying the coating chemistry/photoinitiator package. Isolating the coating from the atmosphere is the most straight forward method of mitigating oxygen inhibition, but it is also the most difficult, particularly when curing large areas. Applicators have attempted to reduce the oxygen exposure by blanketing the exposed area with WebNov 1, 2024 · The maximum photo-curing depth was 14 mm of the KH550 modified SiO 2 coatings and 11 mm of the KH550 modified TiO 2 coatings.
