Analysis of UV-curable materials is possible through two-stage heating.
Using a two-stage heating method with thermal decomposition GC/MS, we analyzed the material of the sealing agent around the display of commercially available smartphones. By heating the sample at a low temperature (250°C) and measuring the gas components generated using GC/MS, we can detect residual monomers and low molecular weight additives (polymerization initiators, antioxidants). Subsequently, by heating at a high temperature (550°C), we can decompose the polymers and estimate their constituent components. This revealed that the sealing agent is made of a UV-curable material.
