  We perform the analysis of predictions of a classical density functional
theory for associating fluids with different association strength concerned
with wetting of solid surfaces. The four associating sites water-like models
with non-associative square-well attraction parametrized by Clark et al. [Mol.
Phys., 2006, 104, 3561] are considered. The fluid-solid potential is assumed to
have a 10-4-3 functional form. The growth of water film on the substrate upon
changing the chemical potential is described. The wetting and prewetting
critical temperatures, as well as the prewetting phase diagram are evaluated
for different fluid-solid attraction strength from the analysis of the
adsorption isotherms. Moreover, the temperature dependence of the contact angle
is obtained from the Young equation. It yields estimates for the wetting
temperature as well. Theoretical findings are compared with experimental
results and in a few cases with data from computer simulations. The theory is
successful and quite accurate in describing the wetting temperature and contact
angle changes with temperature for different values of fluid-substrate
attraction. Moreover, the method provides an easy tool to study other
associating fluids on solids of importance for chemical engineering, in
comparison with laboratory experiments and computer simulations.
