Multiple internal reflectance (MIR) was used to study binder migration of paper coatings. Casein and an acrylic latex were selected as binders because of their characteristic infrared absorption bands. The coatings analyzed were prepared on the Western Michigan University Pilot Coater using the airknife coating method at different coating speeds. A surface grinder was used to obtain several layers of coating for surface studies.

It was concluded that the MIR technique could satisfactorily be used in the binder migration studies. Its success mainly depends on the precision of surface grinding, caliper measurement and infrared characteristics of the binders. The results indicated that drying rate and base stock absorbency were two factors which balance binder migration. An infrared-dried casein-clay coating was found to have considerable binder migration to the surface of the coating.
