Critical review of concepts common to cohesive energy density, surface tension, tensile strength, heat of mixing, interfacial tension and butt joint strength

Prediction of solid–binder affinity in dry and aqueous systems: Work of adhesion approach vs. ideal tensile strength approach

“…(25) are close to the experimental values for MCC, HPMC, EC and PEG. Gardon's [28] correlation is close to the experimental values for acids and water. For PVP, Bonn's [38] correlation is the closest.…”

“…In 1967, Gardon [27] asserted in his treatise that this equation reasonably holds for a variety of materials for which he assumed that k = 16. This constant k varies only between certain limits according to the type of molecules [16] and should be constant for a variety of materials [28].…”

Phase behavior of laundry surfactants in polar solvents

“…Using the solvent polarity scale (π*) of Kamlet et al (19), the data could be fitted equally well (not shown). Earlier work revealed a clear relation between the cohesive energy density and the surface tension of solvents (17,20,21): [1] In this equation, (∆H ev /V ) 1/2 is the Hildebrand parameter (heat of evaporation per molecular volume), k is a temperature-dependent constant, and γ/V 1/3 is the Gordon parameter (surface tension per molar volume 1/3 ). If water is mixed with a solvent, the LC area is larger than the average of the two LC areas (of water and the solvent).…”
