Improved Corrosion Control Through Nontoxic Corrosion Inhibitor Synergies

摘要

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 coat-ings.The most environmentally sound method for surpassing the high anticorrosion stan-dards 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.
