Flexshield, our standard Vinyl Plastisol coating is a flexible, corrosion-resistant, and attractive coating. The high solids content (80% - 90%) and the absence of highly volatile solvents in Flexshield means that it can be applied as a heavy film and then heat-fused to form a durable, continuous coating. It's applied in two coats. The first is a special polymer primer, which enhances bonding. Then, a 4-mil to 8-mil-thick top coat is roll coated to both the interior and exterior surfaces.

Available on:

  • G-90 galvanized

  • Galvalume3003 aluminum

  • Painted aluminum is available as a special order, subject to quantity requirements.

Our vinyl plastisol received an outstanding rating in the Kesternich Cabinet test, the industry-accepted test of environmental, atmospheric, and acid rain pollutants. Its uncommon flexibility will protect your panels, yet remain intact during rolling and fabrication. In tests of color change, chalking resistance, formability, humidity, abrasion and salt spray, it equals or surpasses competitive coatings.

Flexshield Vinyl Plastisol is best when you need the most protection for your building. It's formulated to stand up to the harsh industrial pollutants that quickly eat through standard coatings. An ideal coating for waste water treatment plants, paper mills, chemical processing plants, fertilizer plants and steel plants, it's an investment that pays off in the extended life of your buildings.

Whether a corrosive atmosphere is generated from interior or exterior sources, you have extra protection. Contact us for more information or for help in determining the proper thickness of finish for your specific project.

To meet these specifications, coating must be applied over a properly cleaned and pretreated G-90 galvanized, Galvalume® or aluminum substrate.
