Synergistic Effect of Driers on Soybean Oil-Based Ceramer Coatings

By David Deffar, Mark D. Soucek

Inorganic-organic hybrid coatings were prepared using blown soybean oil with sol-gel precursors. Three sol-gel precursors, titanium tetra-ipropoxide (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 hard-ness, adhesion, reverse impact resistance, and flexibility were evaluated as a function of sol-gel pre-cursor and drier content. Viscoelastic and tensile properties were also investigated.
