<p>A corrosion inhibitor composition for metal working and a method for making the same is provided. The composition is made by reacting maleated tall oil fatty acids with alkanolamines. The alkanolamines suitable for the present invention may be ethanolamines or other alkanolamines such as di-glycolamine if ethanolamines are not environmentally preferred. The resulting reaction product salts provide an effective corrosion inhibitor suitable for incorporation into aqueous products such as buffing compounds, cutting fluids, drawing compounds, cleaning fluids and forging aids.</p> |
