Common Coating Defects Explained In industrial and protective coatings, surface integrity is critical for ensuring long-term performance, corrosion protection, and asset safety. Coatings act as a protective barrier against moisture, chemicals, UV radiation, and aggressive environments commonly found in industries such as oil & gas, construction, marine, power plants, and infrastructure. However, coating defects can severely compromise both the appearance and durability of steel structures. Even

How does powder coating work? Let's find out! The powder is a blend of polymers, pigments, and other ingredients which are mixed in a hopper. The hopper has a fluidizing plate at the bottom which flows air up through the powder, keeping it in a liquid like state for application. Aaron is using his own self-made fluidizing hopper. Now looking at powder coating gun, on the front of it is a corona ring, which is attached to ground and this captures any overcharged powder particles so that they don’
