For Every Action, There’s a Reaction
Southwest Impreglon is home to the brand coatings – Impreglon and Fluorolon®.
Corrosion Coatings: In the refining industry, caustic and acidic chemicals are a fact of life. Corrosion coupons can give the rate of pipe destruction, but critical process equipment needs more. Protection, directly fused at the metal’s substrate level, begins the complex task of fighting chemical and environmental corrosion. The answer, Southwest Impreglon’s proven corrosion coatings for the Refining & Petrochemical industry utilizing proven corrosion preventatives for all metals in fluid transfer and storage.
TSA – Twin Arc Spray Coatings are used extensively in offshore oil & gas applications in both splash zone and subsea environments due to its proven history to prevent corrosion for up to 30 years.
