Optimization of Non-Toxic Anticorrosives in Water Borne Coatings

There are many factors to consider when optimizing your coating system for corrosion resistance. Waterborne coatings present a unique challenge due to their inherent hydrophilic nature and ability to readily conduct electrons. Waterborne resin technology has evolved greatly since its inception. If formulated properly one is able to meet and or exceed the performance of their solvent borne counterparts.

There are many factors to consider when optimizing your coating system for corrosion resistance. Waterborne coatings present a unique challenge due to their inherent hydrophilic nature and ability to readily conduct electrons. Waterborne resin technology has evolved greatly since its inception. If formulated properly one is able to meet and or exceed the performance of their solvent borne counterparts. Prior to choosing a suitable anti-corrosive, the formulator must be aware of the many factors that can influence the end performance of their system. These factors include resin type, substrate(s), PVC, required film thickness, application of the coating, environmental regulations where the coating will be sold/applied, and the end use of the coating, to name a few. When choosing a suitable anticorrosive, the formulator must have a basic understanding of corrosion, coupled with how these various non-toxic anti-corrosives work to slow the corrosion process. In this lecture we will go over the basics of corrosion, explore different mechanisms of corrosion protection specific to waterborne coatings, discuss the importance of anti-corrosive selection, and finally talk about how to formulate with non-toxic anti-corrosives.
