What is the thickness of the coating that requires tripping?

A thickness of 14 mils is noteworthy because it represents a standard threshold for requiring tripping, or the process of halting the application of additional coating until a specific requirement or standard is met. In many coating applications, especially in automotive refinishing and industrial coatings, certain thickness levels are critical to ensure optimum adhesion, durability, and overall performance of the finish.

When coatings exceed this thickness, issues like improper curing, sagging, and reduced appearance can occur. This is why standards often define this specific threshold, making 14 mils an important number in the context of coatings that necessitate careful monitoring and potentially stopping application to evaluate or ensure quality standards are met. The other thicknesses listed may not be considered critical in the same way, hence do not trigger the need for tripping.
