FTIR, AFM and XPS [168], Surface capable infrared techniques, such as ATR-FTIR and PA-FTIR are also suitable tools for in situ analysis of automotive clearcoats [29], ATR-FTIR has further been used to examine skin and core structure of UD-PE film [165], The ATR optical arrangement is a well understood way of obtaining top layer spectra. [Pg.32]

Carter et al. [402] have addressed the chemical assessment of automotive clearcoats (usually melamine-cross-linked systems), which requires evaluation of the cross-linker type, HALS and UV absorbers. Coating systems require a variety of chemical analytical techniques for their evaluation [403], including UV microspectroscopy [402, 404], /xFTIR [402,405], /xRS [406,407], NMR [408], ESR [409], ToF-SIMS [410,411] and hydroperoxide titration [412]. Ideally, what is needed for industrial evaluation purposes is a set of techniques that can follow chemical changes in individual layers of a full automotive paint system, typically consisting of 45 /xm clearcoat, 25 /xm basecoat, 35 /xm primer, and 35 /xm E-coat on metal. The clearcoat must shield underlayers from UV. Unlike the case for IR radiation, examination of 30 /xm and thinner clearcoat layers with 0.3 to 0.4 /xm radiation lends itself quite well to the use of microscopes and microspectroscopic techniques. UV microspectroscopy of 10 /xm paint system cross-sections is the method of choice cfr. also Chp. 1.1). UV microspectroscopy... [Pg.520]

VIEEW (Video Image Enhanced Evaluation of Weathering) is a digital macro scale image analysis system allowing objective, visual evaluations for applications such as automotive clearcoat analysis, texture analysis, delamination, chalking, and defect analysis [243]. VIEEW allows visualisation of chromatic and geometric information, optically defines surface defects, eliminates human subjectivity, and supplies reproducible quantitative data. In... [Pg.654]

Another approach to VOC reduction is the use of powder coatings, however, there is a lot of cost in converting existing spray booths to suit powder application. Hence, a variation on this theme is to use slurries of powder in water as automotive clearcoats. A new dearcoat system has been introduced, that offers zero emissions, is powder dispersed, and is stabihzed in water [7]. This method is used commercially by Daimler-Chrysler in Europe. [Pg.166]
