Abstract
Recently, inorganic–organic hybrid coatings produced by the sol–gel
route have proven to be a potential protective treatment for wooden
surfaces. In this study, the effect of curing process on simulated
antisoiling properties of sol–gel coating was investigated. The sol–gel
coating was spray-coated on pine sapwood and cured with different
temperature and time combinations. The antisoiling properties were
studied by measuring the water contact angle of the coating after
different curing processes. In addition, abrasion resistance and contact
angle of oleic acid were measured. An optical profilometer was used to
investigate surface roughness of the coating. Sufficient hydro- and
oleophobicity were obtained with all of the curing parameters. The
comparison between curing parameters showed that lower temperature and
1–3 h curing time leads to significant improvement in the durability of
the water and oil repellent properties of the coating.
