Sigmazinc 105 Zinc-Rich Primer

Sigmazinc 105 is a premium zinc-rich primer engineered to provide robust corrosion protection for carbon steel and structural steel. Formulated with a high percentage of zinc dust, it offers exceptional cathodic protection, ensuring long-lasting durability even in harsh, aggressive environments such as coastal zones, chemical plants, and heavy industrial facilities.

Key Features & Benefits

• Superior Cathodic Protection: The high zinc content actively protects the underlying steel substrate, preventing rust formation effectively.
• Excellent Adhesion: Bonds strongly to properly prepared steel surfaces, ensuring the coating system remains intact over time.
• High Durability: Resistant to weathering, UV exposure, and chemical splashes, making it ideal for exterior and interior industrial applications.
• Compatibility: Serves as an ideal base coat for topcoats and intermediate coats in multi-layer anti-corrosion systems.

Applications

This primer is widely used on bridges, offshore platforms, storage tanks, pipelines, and general structural steelwork where long-term corrosion resistance is critical. It is suitable for both new construction and maintenance projects requiring reliable surface preparation and protection.
