Coatings properties were evaluated as a function of concentration of reactive diluent in the formulation. The tensile, thermomechanical, and general coating properties were evaluated. General coatings properties included crosshatch adhesion, pencil hardness, impact resistance, and solvent resistance. The siloxane and allyl ether-functionalized soybean oil enhanced the tensile modulus and crosslink density by 20% and 70%, respectively. Coatings with fluorine-functionalized soybean oil showed enhanced contact angle and solvent resistance, compared to alkyd coatings alone. The incorporation of reactive diluents in the formulation improved pencil hardness, while other general coating properties were not significantly affected.
