| Résumé : |
The impact of toxicological concerns on the design of all types of modern anti-corrosive primers has been significant as new raw materials, especially pigments, displace their more traditional toxic forebears. In many cases, these raw materials are less efficient in coatings, and more often than not, performance is system specific. If performance and cost effectiveness are to be optimized, attention must be given to well grounded formulation design practices for each of the three classes of metal primers (zinc-rich primers, barrier primers, and inhibitive primers). Care of the important aspects of such design criteria is optimized PVC/CPVC placement. This is specific to the nature of the primer type involved and changes to suit the protective mechanism on which each primer type relies. This article reviews the mechanisms whereby each type of primer affords protection and discusses the role of PVC/CPVC placement to enhance performance. |
