19. How much DFT required for glass flack coating?

Question

Accepted Answer

The required DFT for glass flake coating depends on various factors such as the type of coating, application method, and environmental conditions.

The DFT (Dry Film Thickness) for glass flake coating can range from 100 to 300 microns.
The specific DFT requirement may be specified by the coating manufacturer or project specifications.
Factors like the substrate condition, desired level of corrosion protection, and coating performance requirements also influence the DFT.
It is important to follow the recommended DFT guidelines to ensure proper adhesion, durability, and performance of the coating.
Examples of DFT requirements for glass flake coatings: 150 microns for offshore structures, 200 microns for chemical processing plants.
