Inverse gas chromatography was utilized to provide the surface [total surface energy (γs), dispersive (γsd) and specific (γssp) components] characteristics of simple Sylgard 184® and hollow glass bead samples. Contact angle goniometer measurements were utilized for comparison of the surface free energy of the solid binder sample and the interfacial tension (surface tension) between a liquid probe material and the solid binder surface. Results include an increased understanding of the surface energies utilizing different measurement methods and the development of methods to characterize and evaluate new binder systems. Final success and progress was measured by the ability to reproducibly measure various surface energies, interactions and other properties of a series of binder systems by inverse gas chromatography and compare to contact angle measurements from both the laboratory and literature.
