Ply-Guard MEA is a high solids, high build Mastic Epoxy Aluminum formulation that cures to a tough, flexible, abrasion resistant film. Ply-Guard MEA is self-priming and has excellent adhesion to rusted steel that has had proper power tool cleaning. It is easy to apply by spray, roller or brush. Ply-Guard MEA has high build characteristics allowing 18 mil WFT or more while providing high sag and run resistance. Ply-Guard MEA is an ideal product for improving and upgrading old and deteriorating coating systems.

Applications

Ply-Guard MEA is used to coat tank exteriors, bridges, metal buildings, exposed structural steel, fertilizer mixing and process installations, process equipment vessels, piping, offshore equipment and for mild immersion service. Ply-Guard MEA has superior overall chemical resistance to a broad range of chemicals in comparison to other high build mastic epoxy aluminum coatings.

Surface Preparation

For Atmospheric Service: Power tool or hand tool clean to remove all dirt, rust, or non-adherent coating. For more severe environments, dry abrasive blasting or water blasting to a commercial blast is preferred. For Immersion Service: Dry abrasive blast to a white metal finish with a 1—1½ mil profile. Over new concrete, etch surface with 10% Muriatic Acid, flush with water and dry.

Applications

Ply-Guard MEA may be applied by spray, brush, or roller. Cross spraying, brush, or roller application technic is highly desirable. Apply to recommended DFT using conventional, airless, brush, or roller methods.

Applications

For Atmospheric Service: Ply-Guard MEA is DMT self priming and can be used as a topcoat over many existing coatings. Contact Polyset Tech. Rep. for specific application recommendations. For Immersion Service: WB HRZS® Primer is recommended. Contact Polyset Tech. Rep. for specific application recommendations.
