Near-Infrared Spectroscopy (NIR) can be used in adhesive production to measure various parameters. The exact parameters measured may vary depending on the specific composition of the adhesive and the objectives of the process. Here are some common parameters that can be measured with NIR in adhesive applications:
NIR can be used to analyze the chemical composition of the adhesive. This involves identifying and quantifying different components, such as polymers, solvents, excipients and additives.

NIR can provide indirect information about the viscosity of the adhesive through correlations with chemical composition and other properties. It is important to note that direct viscosity measurements may be better performed with specialized viscometers.

For adhesives that are curing, NIR can be used to monitor the degree of curing. This can be important for controlling production quality and ensuring the desired properties of the final adhesive bond.
NIR can be used to monitor the quality of raw materials used in the production of adhesives, including the identification of impurities or variations in composition.
NIR can provide information about the molecular structure of polymers in the adhesive. This allows the manufacturer to gain insight into the properties of the polymers used and their influence on the performance of the adhesive.
It is important to note that the implementation of NIR for specific parameters depends on the formulation and manufacturing process of the specific adhesive. It may be necessary to develop calibration curves and adapt the NIR system to the specific needs of the production environment.
