Corrosion Control Coatings
For Every Action, There’s a Reaction
In industries where caustic or acidic chemicals are regularly used, the equipment can wear down at exponential rates. It’s critical for coating systems to have anti-corrosive properties to ensure long-term use and effectiveness. Southwest Impreglon is proud to offer a number of corrosion protection products that are designed to protect metal surfaces from chemical deterioration. Our range of industrial chemicals is guaranteed to keep your equipment at optimal performance, especially under high-temperature and pressure conditions.
