RELEASE ON DEMAND CORROSION INHIBITOR COMPOSITION |
摘要 |
Disclosed is a release on demand type corrosion inhibitor composition for a metal substrate formed from only non-electrically conductive film forming copolymer(s); a nitrogen containing functional group X, where the group X comprises a pyridine, a dihydropyridine, a pyrrole, an imidazole, or a mixtures thereof; and a metallate anion. The metallate anion binds to a nitrogen in the functional group X by ion pairing. A localized rise in pH is believed to cause release of the anion via a protonation/deprotonation reaction and the released anion suppresses the corrosion formation. The coating composition includes no electrically conductive polymers.
