Heavy metal-based corrosion inhibitors were widely acclaimed as the best materials to provide corrosion protection to coatings. The performance of a coating under corrosive conditions requires that corrosion inhibitors provide reliable and sustainable protection during the coatings lifetime. Today, the industry is challenged to be more conscious of the impact that toxic metals have on human health and on other ecosystems. Sol-gel technology offers an eco-friendly alternative to the use of toxic metals (Cr VI, Cd, Pb, Cu, Ni, and Zn). This article highlights research in new sol-gel based corrosion inhibitors for use in paint as well as for use in the pretreatment of bare metals (e.g., steel, aluminum, silver). Sol-gel technology particularly affords superior corrosion protection in thin film coatings (< 25 µm dry), an area that up to now has been dominated by Cr-based anticorrosives. This technology is applicable to most waterborne and solventborne finishes, high gloss direct-to-metal coatings, conventional primers, acrylic clearcoats, fast drying lacquers, wash primers, anti-fingerprint, and conversion coatings.

Improved corrosion control through nontoxic corrosion inhibitor synergies / Andrew Thorn in COATINGS TECH, Vol. 3, N° 5 (05/2006)  

[article]  inCOATINGS TECH > Vol. 3, N° 5 (05/2006) . - p. 24-30 Titre : Improved corrosion control through nontoxic corrosion inhibitor synergies Type de document : texte imprimé Auteurs : Andrew Thorn, Auteur ; Amanda Adams, Auteur ; Tony Gichuhi, Auteur ; Wendy Novelli, Auteur ; Mary Ann Sapp, Auteur Année de publication : 2006 Article en page(s) : p. 24-30 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 667.9 Revêtements et enduits Résumé : The idea of anticorrosive synergies is not a new concept but one that still holds a lot of promise for advancing the performance of environmentally compliant protective coatings. The most environmentally sound method for surpassing the high anticorrosion standards set by toxic inhibitors such as lead- and chrome-base inhibitors is through the gains provided by nontoxic corrosion inhibitors synergies. In order to realize the benefits that exist from combining inhibitor chemistries, one must first understand the mechanisms surrounding corrosion, the inhibitors themselves, and the key formulating guidelines required for success. “Solubility optimization” of the inhibitors in the coating film is an important factor for improving anticorrosive performance. Resin type and formula parameters play a significant role in inhibitor selection and use level. This synergistic approach for improving performance also carries through to other components such as extender pigments and additives. Once the synergistic balance is achieved, the results are a clear indication of the power of this theory.
