What are the application values of infrared spectroscopy? After reading this article, you will understand

There is an extensive literature on the use of IR spectroscopy in coatings, including a recent review. Major IR spectrometer manufacturers, such as Nicolet, Perkins-Elmer, Bio-Rad, and Bomem, have applied experiments staffed by experienced analysts. room. Laboratories in the coatings industry have experienced infrared spectroscopy experts. All of these can be valuable sources of help. Infrared spectroscopy is often used in conjunction with other techniques, including thermal, electrochemical and other spectroscopic methods, to study coatings.

An important application of infrared spectroscopy in coatings is chemical analysis and determination of the composition of the coating. Infrared spectroscopy is unique in its ability to identify virtually all coating components, including volatile solvents, resins and polymers, inorganic and organic pigments, and a wide variety of additives. The use of solid sampling accessories for the analysis of coatings is reviewed, as is the analysis of polyester resins and alkyd resins. This paper reviews the use of infrared spectroscopy for packaging food coatings and surface analysis, and infrared spectroscopy for glass substrate coatings. Applications in Analysis Forensic chemists rely on infrared spectroscopy, especially infrared microscopy, to identify paint chips and other coatings. Their focus is to match samples to specific sources, such as cars. Diamond-shaped anvils are useful for forensic analysis in many different situations where the identification of paint and its components is required. Manufacturers or formulators can use infrared spectroscopy to identify contaminants and check the quality of raw materials. Manufacturers use IR to analyze their own or competitors' products.

Infrared spectroscopy is very useful for studying changes in coatings. Subsequent polymerization reactions such as those that occur during paint production or after application Other examples include curing of epoxy-based paints, automotive clear coats and powder coatings. The delamination phenomenon of multi-component coatings was investigated using ATR and step-scan photoacoustic infrared techniques. Defects in the coating can be studied and the degradation of the coating over time, temperature or adverse conditions can be monitored. Identification of degradation products and elucidation of degradation patterns. The degradation of polyurethane and epoxy resins was studied by step-scan photoacoustic infrared spectroscopy. The use of infrared spectroscopy for UV durability prediction is reviewed. In situ monitoring of coatings is possible. Otherwise, the coating needs to be applied in a way that can be seen by infrared. For example, coatings can be applied to ATR crystals.

Infrared spectroscopy can be used to study surface phenomena related to coatings. This article reviews the use of infrared spectroscopy for surface analysis, including depth profiling. Such as the inspection of polymer and coated paper. Other surface applications include monitoring acrylate polymerization, observing silicone additives, studying polyurethanes Infrared spectroscopy is useful for interfacial studies, studying interactions between coatings and substrates, air, liquids, and embedded fibers. Interactions between air and latex films have been studied using diffuse reflectance infrared spectroscopy at the interface.

Infrared spectroscopy has a wide range of applications in the field of coatings. Most coating problems can benefit from the study of infrared spectroscopy.
