On-Line Monitoring of Epoxy Value with a ClearView db Photometer

Pages 1 Pages

Purpose: To measure epoxy value and starting liquid resin content with the two-channel ClearView db photometer and ? ber optic insertion probes with simple, easy-to-maintain, linear calibrations. Approach: The NIR peak at 2208 nm is traditionally used to measure epoxy value. However, this intense peak requires a narrow optical path (2 mm). Also, the basic liquid resin starting material is a spectral interferent, requiring more sophisticated
