Nick's Niche: Understanding corrosion (April 2008)
Greetings and salutations from Connecticut! In the 1990s, I wrote a regular column for Powder Coating magazine titled “Inside Information.” The column tackled a diverse range of topics on the powder coating process from color change to high-technology gizmos. Several of my associates at Powder Coating Consultants, including George Trigg, also contributed to the column. Although we enjoyed writing it, we got the opportunity to write the Questions & Answers column for this magazine. Eventually, I went on to write a similar Q&A column for another publication while George took over the column for Powder Coating. Well, I’m back with a guest column to be published occasionally throughout the year, and am thankful for the opportunity to once again write for the first publication dedicated to the powder coatings industry—Powder Coating magazine.
I frequently discuss with our clients how to improve the corrosion resistance on their products. Let’s face it, many manufacturers use powder coatings for their excellent corrosion-resistance properties. Often clients will say that was the primary reason they selected powder coatings as their finishing technology. However, some end users never realize their corrosion-resistance objectives. The trouble often starts with unrealistic expectations and can be further impacted by faulty product design and poor execution of the powder coating process. Here we will discuss all of these issues to help you better understand how you can better improve your product’s corrosion resistance.
