ALUMAPROTECT (2-USGL-KIT)

Additional Product Information

Overview

This two-component epoxy-polyamide aluminum primer is designed to provide long-term corrosion protection and strong coating adhesion on properly prepared aluminum surfaces. In aviation and MRO environments, it is used as a high-reliability base layer before epoxy build primers and topcoats, helping protect structures exposed to moisture, salt air, hydraulic fluids, and industrial chemicals. Maintenance teams rely on it for its dependable bonding performance, predictable cure schedule, and excellent resistance in harsh service conditions.
