U-497 is a three-component, zinc-rich polyamide epoxy primer for use on metal substrates in severe corrosive or salt environments or anywhere the substrate requires cathodic-type protection from its primer. Designed for easy application by brush, roller or spray, it provides long-term corrosion protection. When paired with U-166, U-499 or U-111 as a topcoat, it provides added salt corrosion protection and longer life, along with color, gloss and other benefits.
