Coatings for drinking water and food products: material selection and permitting documents
In a tank for drinking water or a food product, the lining likewise protects the contents more than the steel. But those contents have a property fuel does not: a human consumes…

Storage tanks for Jet A-1 and TS-1 aviation fuel
In an aviation fuel tank the lining protects more than the steel. It protects the fuel. That inverts the usual logic: in an ordinary tank we worry that the medium will damage…

Corrosion protection of steel structures: 3-in-1 primer-enamel or a separate system
Unprotected steel structures corrode: moisture, condensation, industrial atmosphere and aggressive media destroy the metal, and repair or replacement costs more than a timely coating. In practice the choice is between two approaches:…

Why coatings fail early: ultraviolet and cutting corners on the topcoat
Ultraviolet does not cause corrosion. It destroys what prevents it. That distinction sounds like semantics until you see a site where the coating was specified entirely by the book — right environment…

Surface preparation for protective coatings: where you must not cut corners
A coating holds not because of the paint, but because of what it was applied to. Among protective coating failures, surface preparation is cause number one by a wide margin. And it…

Internal corrosion protection of tanks: choosing a lining for an aggressive medium
The outside of a tank can be repainted. The inside, practically speaking, cannot. To reach the internal surface the vessel must be emptied, cleaned, gas-freed and ventilated, and the whole unit taken…

Corrosion of steel structures: consequences and protection methods
Corrosion is not an event but a process with a known rate. It cannot be “prevented” once and for all — it can only be slowed to a rate at which the…
