Red Lead Primer is a high-performance, alkyd-based coating designed to protect steel structures from corrosion in industrial, marine, and infrastructure environments. Formulated with red lead pigment, it offers superior adhesion, impact resistance, and long-term durability—even over marginally prepared surfaces.
Recommended for bridges, oil storage tanks, refineries, cement plants, and general steelwork, this primer performs well under adverse application conditions. It features a volume solids content of 55–58%, with a theoretical coverage of 13–18 m²/Ltr/coat at 30–50 microns DFT.
Drying times vary by temperature: touch dry in 30 minutes to 3 hours, hard dry in 6–24 hours. Recoat intervals range from 8 to 20 hours. Application methods include brush, roller, and airless spray. Compatible topcoats include synthetic enamels and alkyd finishes.
Red Lead Primer surface preparation should meet SSPC-SP2 or Sa 2 standards. The product is packaged in 3.785L and 18.925L drums, with a shelf life of 12–24 months. Use CMP-21 or enamel thinner for dilution and cleanup. Safety precautions are essential due to lead content—dry film is toxic if ingested
