Synergistic effect of driers on soybean oil-based ceramer coatings

Inorganic-organic hybrid coatings were prepared using blown soybean oil with sol-gel precursors. Three sol-gel precursors, titanium tetra-i-propoxide (TIP) titanium (di-i-propoxide) bis (acetylacetonate) (TIA), and zirconium tetra-n-propoxide (ZrP) were used in conjunction with cobalt, manganese, and zirconium driers. The goal of this study was to investigate if a synergy exists between the drier and sol-gel precursors with respect to the autooxidation process. Various coating properties such as hardness, adhesion, reverse impact resistance, and flexibility were evaluated as a function of sol-gel precursor and drier content. Viscoelastic and tensile properties were also investigated.
