What is the dry film thickness (DFT) of the tack coat for Nonskid primer?

• A. 1 to 2 mils
• B. 1 to 3 mils
• C. 2 to 3 mils
• D. 2 to 5 mils

Answer: (A)

The dry film thickness (DFT) of the tack coat for nonskid primer is typically specified to be between 1 to 2 mils. This range ensures that the primer adheres effectively to the substrate and provides a suitable surface for subsequent layers, promoting optimal performance and longevity. A tack coat that is too thick may lead to curing issues and a potential failure of the coatings system, while a coat that is too thin could compromise adhesion and durability. Therefore, the 1 to 2 mils specification strikes the right balance for effective application in aviation settings.
