Modern Pretreatment Strategies for Multiple Metals
This presentation features an up-to-date look at pretreatment strategies for a variety of metals. Steel-making techniques have succumbed to the cost-cutting measures that now affect almost every industry, resulting in substrate of highly variable quality. Job shops and other coaters need a robust approach to ensure highest possible finish quality and durability. One of the strengths of modern zirconium pretreatments is their broad adaptability to a range of applications. Tips and strategies for coating aluminum, zinc (galvanized), and magnesium will also be discussed. Finally, some techniques for passivation or coating stainless steel will be shared.
Dr. David B. Chalk holds B.S., M.S., and Ph.D. degrees in chemistry from the University of Cincinnati. In his 28-year industrial career, he has researched steel making practice, corrosion mechanisms, surface science, and chemical pretreatment applications. As the inventor of the first zirconium-based sealer application for steel in 1995, Dr. Chalk is the industry’s foremost expert in modern transition metal pretreatment theory and practice. Currently working in the laboratories of DuBois Chemicals, Dr. Chalk’s focus is on improving application of zirconium pretreatments, research in organic pretreatments, and discovery of the next generation of pretreatments.Location:
