Measurement of 2 Part Epoxy Glue (Araldite) Curing Using the Specac Quest ATR Accessory

An alternative method for spectral collection in infrared spectroscopy is to use the Attenuated Total Reflectance (ATR) technique. In this application note it is demonstrated that the Specac Quest™ ATR accessory with a diamond puck is suitable for use in applications whereby a sample such as a two part epoxy resin adhesive can be studied for its reaction of bonding and co-polymerization. The use of a diamond crystal as the ATP top plate allows for a wide spectral range in the IR from 4000cm^-1 to 400cm^-1 to be studied and recorded.
