Modified alkyd resin as an anti‐corrosive binder for paints

Modifies short and medium alkyd resins using perfluori‐nated urethane toluene isocyanate (PFUTI), and incorporates the modified resins in a set of paint formulations containing different ratios of zinc phosphate as an inhibitive pigment. Achieves promising results and illustrates corrosion‐protective properties in various paint formulations and also a paint formulation free of the inhibitive pigment. Shows enhancement of the corrosion protection efficiencies by the improvement in the hydrophobicity of alkyd resin modified with PFUTI. In view of these results, minimizes or neglects the most expensive inhibitive pigments from an economical standpoint.
