Sherwin-Williams Launches Styrene-Free Vinyl Ester for Severe Chemical Resistance

Sherwin-Williams Protective and Marine Coatings has launched Magnalux 404 FF, the first styrene-free vinyl ester for use with steel and concrete substrates in the oil and gas market. The new coating is specially formulated to combat immersion and containment service corrosion caused by contact with aggressive chemicals such as aromatic solvents, hi-aromatic gasoline, ethanol gasohol, MTBE, ETBE, TAME and ether/fuel blends.

Magnalux 404 FF is a low-VOC (<15g/L), flake-filled, chemically resistant premium tank lining that offers improved chemical and temperature resistance. Flakes, made of a crystalline form of iron oxide, provide improved edge protection and abrasion resistance. The flakes create a physical barrier that resists corrosion from fluid migration.

Because Magnalux 404 FF is styrene-free, it will not shrink and pungent odors are nearly eliminated. The 100 percent solids product can also be applied in one coat and still achieve the correct thickness. It will cure tack-free without a wax solution, allowing for one less step in the application process and making the cleaning process even simpler, according to the company.
