Case study AU0012 – Chesterton ARC products – Industrial Coatings

Chesterton - Global Solutions, Local Service



Severe corrosion within a saltwater strainer from a blast furnace lead to replacement of the full strainer every two-to-three years. Our client wanted to find an alternative coating that could resist these forces, and reduce maintenance costs and replacement downtime. Chesterton specialists recommended Chesterton® ARC SD4i to protect the steel strainer. The client confirmed that the product provided long term corrosion protection in salt water applications, and the high gloss finish minimised unwanted build up.
