The Dispersant Effect, Corrosion Control with Aqueous DTM Coatings


"The Dispersant Effect, Corrosion Control with Aqueous DTM Coatings"
Presented by David Tarjan
 

In recent years the coatings industry has been challenged with designing and developing aqueous direct to metal coatings to replace incumbent solvent based systems. Advances in corrosion inhibition through synergistic effects combining inorganic/organic inhibitors have shown to be effective in corrosion prevention through metal passivation and adsorption. The role of dispersant technology on corrosion is often overlooked. Polyacrylate and Polyalkoxylate chemistries offer effective wetting and dispersing however can negatively impact film hydrophobicity and, thus, the corrosion protection properties. Controlled flocculating dispersants offer wetting and anti-settling while maintaining anti-corrosive properties. Pigment affinic groups also play a role and are discussed in conjunction with specific dispersant chemistries. This paper captures the critical role dispersants play on direct to metal anti-corrosive aqueous coatings. Through rheological analysis, accelerated testing and electrochemical analysis this paper identifies the electrochemical behavior of dispersants as it relates to performance, specifically corrosion prevention in aqueous direct to metal coatings.
