“…Three types of silica (silicon dioxide), crystalline silica (quartz), diatomaceous silica, and synthetic silica, have been used in various layers of automotive finish systems . They are used in undercoats to promote adhesion and lower costs and have also been employed as flatting agents to produce flat black nonmetallic finishes, as observed for some monocoats from the Reference Collection of Automotive Paints . Synthetic silica is used frequently as a viscosity control agent in clearcoats and in basecoats having light pigment loads .…”

Bismuth oxychloride (BiOCl) was the first viable synthetic pearl pigment developed 50 years ago. It was only used for a limited time period in automotive paint (model years 1998-2000), serving to produce luster for a single Chrysler black metallic color. Identification of this pigment in an unknown automotive paint can thus facilitate determination of the vehicle of origin. Bismuth oxychloride imparts effects similar to those produced by silver/white mica pearlescent pigments, and such a pigment was used together with bismuth oxychloride in at least one original equipment manufacturer (OEM) basecoat. Silver/white micas are now used primarily in white pearl tricoat systems. This article describes the identification of bismuth oxychloride and silver/white mica pearlescent pigments in automotive finishes using FT-IR spectroscopy, X-ray fluorescence (XRF) spectrometry, and SEM/EDS analysis. Data for some cadmium pigments, which were used in automotive paint several decades ago, are also presented as they produce infrared absorptions similar to that of bismuth oxychloride.
