Coatings for aluminum for various applications

Ensure the utmost quality for your aluminum semi-finished products or business assets with a professional aluminum coating from Lakfabriek Korthals. Coated aluminum offers numerous benefits. You can (1) count on optimal material preservation, (2) have various options to enhance its appearance, and (3) often add additional properties. Below, you’ll discover the applications suitable for aluminum coatings, why wet coating is preferred, and the key considerations for achieving the desired end result.

Extend the lifespan of aluminum with a coating

We believe that what is beautiful should remain beautiful. With a coating, the corrosion resistance is increased, while simultaneously enhancing the aesthetic value, ensuring a more durable end product.

Common methods explained

Coating aluminum typically occurs in three ways: anodizing, powder coating, and wet coating. Below is a brief explanation of each application method:

• Anodizing involves an electrochemical treatment where the metal to be coated is provided with an oxide layer only a few nanometers thick;
• Powder coating involves an electrostatic painting process where powder is sprayed onto metal and then cured by heating;
• Wet coating involves the manual or robotic application of a liquid coating. Wet coatings can be applied via spray application, brush, or roller.

The advantages of wet coating

Of the above application methods, wet coating is known as the most practical, user-friendly, and decorative solution. Below are the reasons why:

• You don’t need to consider maximum dimensions.
  • With anodizing, you are bound by the size of the applicator’s machinery.
  • With powder coating, the objects to be coated must fit into a spray booth;
• There is a wealth of colored finishes and decorative options available.
  • With anodizing, the color choice is relatively limited, especially when opting for high-gloss finishes.
• Surface repair is easily done.
  • With anodizing, layers showing faults or cracks can no longer be repaired.
  • With powder coating, localized repair is almost always visible in the end result.
