According to van Oss et al., surface acidity parameter γ
+, and basicity parameter γ
-, together with dispersive force parameter γ
LW of paint films and substrates were determined by contact angle measurements.
Hexane, diiodomethane and ethylene glycol were used as diagnostic liquids. The interfacial tension γ
sp between a paint film and a substrate was calculated from these parameters and correlated to their adhesion behavior. A negative value of γ
sp was an indication of excellent adhesion, in practice.
