Infrared spectroscopy is one of the few analytical techniques considered by the forensic science community to have the highest discriminating power required to provide confirmatory evidence about the chemical composition of a material.
Infrared (IR) spectroscopy is used extensively to characterize the chemical composition of trace evidence such as paints, fibers and adhesives as well as seized drugs and related chemicals. Thermo Fisher has recently introduced the Thermo Scientific™ iS™50 ATR module, a novel, extended-range attenuated total reflectance (ATR) module that is integrated into the Nicolet™ iS50 FT-IR spectrometer.
From this testing, it is clear that the temperature of the paint at the nozzle has a significant, measureable impact on surface finish and that each layer (basecoat, clearcoat, etc.) plays a role in the appearance of the final part.
General Motors is introducing a flame treatment technology that lets paint stick to plastic vehicle parts like instrument and door panels without using primers that contain solvents and can foul the air.
