Zingalufer – 1-Component Polyurethane Intermediate Sealer Coat

Zingalufer — The Sealer That Locks In Your Galvanic Protection

Zingalufer is a single-component, moisture-curing polyurethane intermediate coat specifically formulated to seal and protect Zinga cold galvanizing compound. Applied between the Zinga base coat and the topcoat, it acts as a barrier that prevents topcoat solvents from attacking the zinc-rich Zinga layer — ensuring the galvanic protection remains fully intact throughout the coating system's life.

Designed for use on steel structures in aggressive environments, Zingalufer is the critical link in a high-performance, long-lasting corrosion protection system.

Key Features

• 1-component polyurethane — no mixing required, ready to use
• Seals the Zinga galvanic layer before topcoat application
• Prevents solvent attack from topcoats on the zinc-rich base
• Excellent adhesion to Zinga and most topcoat systems
• Moisture-curing formula — suitable for humid and outdoor conditions
• High flexibility and impact resistance
• Available in 10 L containers

Typical Applications

• Steel structures, bridges, and industrial frameworks
• Pipelines, tanks, and offshore structures
• Agricultural and construction machinery
• Any steel surface previously coated with Zinga cold galvanizing compound

Application

Apply by brush, roller, or airless spray over a fully cured Zinga base coat. Allow Zingalufer to cure fully before applying the desired topcoat. Refer to the Zinga technical data sheet for full application guidelines, coverage rates, and overcoating intervals.
