Standard Guide for FT-IR Fingerprinting of a Non-Aqueous Liquid Paint as Supplied in the Manufacturer's Container

Importancia y uso:

5.1 The ability to collect an infrared spectrum of a liquid paint as supplied in the container from the manufacturer is of significant importance when performing qualification testing. Historically, fingerprinting a material for such purpose involved separating the components of the paint and collecting an infrared spectrum of one or more of these components (vehicle, pigments, solvent, etc.) with Test Method D2621 being used for the identification of the vehicle. This unfortunately provides information only on the portion of the liquid paint analyzed whereas the technique shown in this practice provides a more complete picture of what is in the container provided. In addition, user expertise and time required to collect a spectrum is minimal versus traditional standards.
