| Résumé : |
For several years now wateborne coatings have gained acceptance as alternatives to solventborne coatings. For light duty and industrial maintenance coatings for metal, water reducible alkyds and water dispersible alkyds are acceptable alternatives to solvent-based alkyds. Water-dispersible alkyds are made dispersible by neutralizing the acid moieties of the alkyd with ammonia or water soluble amines such as triehylamine. Water reducible and dispersible alkyds (to a lesser extent) are susceptible to hydrolysis and furthermore destabilization by basic multivalent cations such as those found in corrosion inhibiting pigments. The hydrolytic instability translates to limited storage time. This paper highlights research to develop corrosion inhibitors for both types of waterborne alkyds and adresses strategies to overcome stability problems inherent in these systems. |
