FTIR Fingerprinting of Raw Materials for Epoxy Paint Manufacturing

02 June 2020 Institute of Materials, Malaysia|A

Consistency of raw materials for epoxy paint manufacturing was investigated. Selected raw materials comprised of EpikoteTM resins and some organic solvents collected from different paint manufacturers are discussed in this study. FTIR spectra of raw materials were compared using a commercial FTIR software utilizing high sensitivity compare function. With acceptance criteria of degree of similarity (r) ≥ 0.898, results show that a normal grade EpikoteTM yields r value below 0.898 when compared to that of premier grade EpikoteTM. All studied samples including solvents exhibits homogeneous mix across different sampling locations (Top, Middle and Bottom) in the sample containers and Top location can be used for QA/QC purpose.
