ALKA 416

1-Componenet Epoxy Cold Galv Coating System

Alka 416 is a single-component protective coating designed to provide corrosion resistance to steel surfaces through a high concentration of zinc-rich pigments. The term “cold galvanizing” refers to the coating’s ability to offer protection similar to hot-dip galvanizing without the need for high-temperature zinc immersion processes. It is commonly used for maintenance, repair, and touch-up applications on galvanized and steel structures.

Alka 416 contains epoxy-modified resin and metallic zinc dust, which work together to create both barrier protection and sacrificial cathodic protection. When applied to steel, the zinc particles corrode preferentially instead of the steel substrate, helping prevent rust formation and extending the life of the metal surface.

Unlike conventional two-pack epoxy coatings, Alka 416 is a single-pack system, meaning it does not require mixing with a separate hardener before use. This makes it easier and faster to apply, especially for maintenance work, field repairs, and small-scale industrial applications. It can typically be applied by spray, brush, or roller.

Alka 416 is widely used on structural steel, pipelines, storage tanks, fences, towers, marine equipment, and welded or damaged galvanized areas. It provides good adhesion, fast drying properties, and resistance to weather, moisture, and mild industrial environments.

Although it offers excellent corrosion resistance for a single-pack coating, its durability and chemical resistance are generally lower than those of two-pack zinc-rich epoxy systems. Nevertheless, it remains a practical and cost-effective solution for steel protection and galvanizing repair work.

APPLICATION INSTRUCTIONS

Alka 416 generally does not require a separate primer because it acts as both a primer and a protective zinc-rich coating.

It is specifically designed to be applied directly onto properly prepared steel or galvanized surfaces. The high zinc content provides anti-corrosive and sacrificial protection similar to galvanizing, while the epoxy-modified resin ensures adhesion and film formation.

Typical Application

  • Directly onto bare steel
  • Over blast-cleaned steel
  • On damaged galvanized areas
  • On welds and fabrication repairs

 Although no separate primer is usually needed, the surface should be clean, dry, and free from oil, grease, rust, salts, and loose contaminants.

  • Conventional spray
  • Airless spray
  • Brush or roller for small areas and touch-up work
  • Temperature: 10°C – 40°C
  • Relative Humidity: Below 85%
  • Thinner: Synthetic thinner / epoxy-compatible thinner (as per manufacturer)
  • Equipment cleaning: Same as thinner

CLEANING OF EQUIPMENT
Xylene can be used for cleaning tools and equipment before the mixed compound begins to harden. Once cured, it can only be removed mechanically.
