Novol 90408 Alu-Zinc Primer – High-Performance Cold Galvanizing Spray (400ml)
Protect your steel surfaces with the electrochemical power of Novol Alu-Zinc Primer. This 400ml aerosol is a professional-grade, quick-drying primer based on a high-purity blend of Aluminum and Zinc pigments. It is specifically engineered to provide "active" cathodic protection against corrosion, making it the ideal solution for protecting welds, cut edges, and exposed chassis components.
The unique combination of Zinc (for galvanic protection) and Aluminum (for a bright, heat-resistant finish) ensures that even if the coating is scratched, the zinc will "sacrifice" itself to prevent rust from forming on the underlying steel.
Key Features & Benefits
- Double Action Protection: Combines the anti-corrosive properties of zinc with the aesthetic brilliance and oxidation resistance of aluminum.
- Excellent Thermal Stability: Withstands temperatures up to 400°C–500°C, making it suitable for engine components, exhaust manifolds (exterior), and areas near heat sources.
- Electrical Conductivity: Excellent for "spot welding" (Weld-Through) applications, ensuring a clean electrical arc while protecting the internal surfaces of a joint from rust.
- Rapid Drying: Reaches a "dust-free" state in just 10–15 minutes, allowing for fast processing in a busy workshop or DIY environment.
- Spot Repair Specialist: Perfect for treating "fresh" welds or ground-down areas to prevent flash rusting before the full painting process begins.
- Aesthetic Finish: Dries to a smooth, bright silver-grey finish that closely matches the appearance of freshly galvanized steel.
