Moody’s Coating Conundrums

“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!

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.

In this webinar, we will demonstrate how silane and silicone technologies can modify polyaspartic chemistries to increase performance characteristics of traditional metal coating finishes. In particular, we will highlight technical capabilities of glycolic silane technology that can enable coating system formulations to be virtually free of latent alcohol or other VOC emissions.

This webinar will discuss the different chemistries of fluorosurfactants and other additives and how this affects their performance in coatings. Fluorosurfactants are multifunctional and direct one-for-one replacement is rarely possible, but careful selection of additive combinations can achieve comparable performance in different coatings formulations.
