Measurement of Curing Process of Photoolymer Materials by Conductivity Change, Contact Angle and Corresponding Change of FT-IR Spectrum

Abstract

It has been reported that the real time evaluation of UV curing process of photo-polymerization materials is possible by the measurement of photochange of UV ink conductivity. The conductivity method has a well correlation to the curing evaluations of UV ink by contact angle method and FT-IR spectrum method.
