Reaction Tracking of UV-Curable Resin by Rapid Scan

User Benefits

- The IRXross FTIR permits acquisition of infrared spectra at a rate of up to 20 spectra/second. - Detailed observation of curing reaction processes with reaction completion times of several seconds is possible. - Rapid Scan measurement software has various analytical functions such as reaction rate calculation and is an extremely effective technique for tracking chemical reactions and changes.

Introduction

Polymer materials have a molecular structure which is altered by mixing, heating, or irradiation with light. In some cases, those changes are completed in several seconds, while in others they proceed slowly over several hours. Because the Fourier transform infrared spectrophotometer (FTIR) enables high- speed measurement, FTIR is an extremely effective technique for tracking chemical reactions and changes that proceed very quickly. This article introduces the results of measurement of the reaction process of a UV-curable resin using the Rapid Scan function of IRXross, a new FTIR from Shimadzu Corporation.
