“Moody’s Coatings Conundrums” reflects the style of NPR’s classic weekly auto mechanic radio talk show, “Car Talk”, with hosts Click and Clack. While the subject of “Car Talk” was automobiles and auto repair, “Moody’s Coatings Conundrums” targets coatings science, and the many problems that formulators face. This is meant to be an interactive column, so please leave your feedback in the comment section on how to solve these issues!
Polly Mertz's new emulsion batch was delayed due to some of the ingredients freezing when left overnight on the dock. Polly, eager to start her batch scale-up, had approved placing the drums in a steam-heated room in the plant to allow for warming and easy pumping. What was the material that caused the problem, and what mistake had Polly made in heating up those frozen drums?
Al Kidd's first sign of a problem was the strong, acrid smell that burned his nose. What was the material in the drum that caused the smoke? What had caused the material to react so violently?
Why did replacing the ester alcohol with a less volatile ester solvent cause the e-coat tank to now be out of specification? What had been wrong with Lindsey’s recommendation?

Even though the coating properties of the new alkyd formulation matched perfectly the properties of the old formulation, what had been the unforeseen consequence of changing one oil for another in the formulation?

Saul Vance's boss was telling him that the formulation that Saul had developed and tested was being pulled from the market, and Saul can't understand why. Find out was the formulation pulled from the market, and why a change in solvent make the formulation no longer sellable, even though the properties were so similar.
