Some polymeric materials have a molecular structure that is altered due to treatments such as mixing, heating, light irradiation, etc. Some of these changes take place within seconds, while others progress slowly
over several hours. A Fourier transform infrared spectrophotometer (FTIR) is an instrument that is extremely effective for tracking chemical reactions and changes because measurements can be conducted very
easily and quickly.
Here, using the Shimadzu IRTracer-100 FTIR spectrophotometer Rapid Scan feature, we introduce the results of measurement of the curing reaction process that occurs in UV-curable resin.
