Perdure Universal Primer is a one-component, moisture-cured polyurethane primer. It has excellent adhesion to lightly rusty steel, other marginal or poorly prepared metal surfaces, and properly prepared concrete. Perdure UPr undergoes a rapid molecular weight change as it polymerizes into a high molecular weight primer with excellent corrosion, abrasion, and high-temperature resistance. It can be used as a primer for all Macrylex (MMA) based systems. Perdure UPr must be sued as a barrier primer applied in one or two coats as needed to achieve a pinhole-free finish when applying Macrylex over an existing epoxy basecoat.
