Artificial aging of acrylurethane and alkyd paints: a micro-ATR spectroscopic study

Accelerated UV ageing studies of acrylic, alkyd, and polyvinyl acetate paints: Influence of inorganic pigments

“…The absorption variation of the CH 3 Furthermore, after UV exposure of the alkyd binder it was noticed that the peak at 974 cm -1 of the out of plane =CH bending of trans-structures gradually became a shoulder (Fig. 3c), mostly due to the oxidation of the double bonds [27,28] or possibly through Norrish type I and II reactions [27]. …”

“…The broadening of the carbonyl stretching band of the acrylics and alkyd shows the formation of newly photo-degraded products such as carboxyl acids, ketones and aldehydes [24][25][26][27].…”

Improving the UV degradation resistance of epoxy coatings using modified carbon black nanoparticles

“…The goal was to investigate the effect of CB nanoparticles on improvement of the UV resistance of epoxy-based coatings via elimination of a resistant topcoat against UV such as polyurethane in coating system. There are extensive studies on photo-degradation of some of the conventional organic coatings by employing spectroscopic (IR and UV-vis) techniques [18][19][20][21]. In attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, both qualitative and quantitative analyses of samples can be carried out over wide spectral ranges [22].…”

Data on Specific Polymers

“…24 Exposure to wet condensation and salt spray did not result in crosslink loss, which bears testimony to the relatively good resistance of alkyd resins to hydrolysis. UV light must be present for typical changes to occur.…”
