Introduction
Cold galvanizing, also known as zinc-rich paint, is a practical method to shield metal surfaces from rust and deterioration. This article will explain cold galvanizing, highlight its differences from hot-dip galvanizing, describe the application process, and introduce Oiltech Malaysia, which offers Spanjaard cold galvanizing spray and paint.
What is Cold Galvanizing?
Cold galvanizing applies a protective zinc coating to steel or iron surfaces. This zinc layer acts as a sacrificial barrier, safeguarding the metal beneath against corrosion from moisture and chemicals. Cold galvanizing is preferred when immersing the object in molten zinc, as with hot-dip galvanizing, isn't feasible.
Key Differences between Cold Galvanizing and Hot-Dip Galvanizing
Temperature: Hot-dip galvanizing uses high temperatures (around 450°C) for immersion in molten zinc, creating a thick and uniform coating. Cold galvanizing is performed at room temperature, resulting in a thinner zinc layer.
Zinc Coating Thickness: Hot-dip galvanizing yields a thicker coating (3-6 mils), suitable for heavy-duty applications. Cold galvanizing typically produces a thinner coating (0.5-3 mils).
Application: Hot-dip galvanizing immerses the entire object, which may not be practical for complex or large structures. Cold galvanizing allows for touch-ups and spot treatment.
How to Apply Cold Galvanizing
Surface Prep: Thoroughly clean the metal surface, removing rust, dirt, and oil.
Primer Application: Apply a zinc-rich primer to create a base coat. Let it dry.
Cold Galvanizing: Apply cold galvanizing spray or paint evenly. Follow the product's instructions regarding coats and drying times.
Curing: Allow the coating to cure at room temperature.
