The difference between Anodizing and Powder Coating.

The difference between Anodizing and Powder Coating.

Aluminum surface treatment is an indispensable step to help shaped aluminum bar products increase aesthetics, color durability, improve abrasion resistance and withstand harmful weather agents. Currently, there are two most advanced surface treatment methods: powder coating and anodizing. Join Tanminh to learn the differences between these two methods and their advantages.

1, Anodizing

Anodizing  also known as amode painting, is a surface treatment method through electrochemical processes to increase the thickness of the natural oxide layer on the . The Anodizing process helps increase hardness, durability, and aesthetic value of aluminum, providing a perfect protective layer to resist the negative effects of weather and abrasive mechanical impacts.

Advantages of Amode paint:
- Aluminum Anode is light and non-conductive aluminum - The bond of aluminum Anode is not weakened by oxidation. The "aluminum rust" layer created after the oxidation process is still a permanent part of the original aluminum structure and will not change to another form, or be easily lost due to mechanical impact.

- Improves the wear resistance of the aluminum oxidation layer

- Anode aluminum can be colored to increase the aesthetics of the product. Thanks to the good adhesion of the anode coating, the color of the aluminum anode material after dyeing is very durable over time.

- In addition, aluminum Anode has a self-lubricating electrochemical oxidation film, reducing the friction coefficient on the aluminum surface, has good electrical insulating properties and creates many unblemished pores, easily staining the aluminum.

2. Powder coating

Powder coating is a painting technology that uses electronic principles to create adhesion for the paint film. To put it more simply, it means coating a layer of plastic on the surface of the details that need to be covered. Among them, the most common plastics used in powder coating technology are thermoplastics and thermosetting plastics.

Advantages of powder coating - Powder coating has high adhesion, covering about 70% of the surface. After heating, the surface coverage percentage reaches its maximum, bringing high aesthetic value.

- Environmentally safe: powder coating components do not contain organic compounds that affect the climate and handling after use. - Excess paint powder during the spraying process is recovered and reused. There is also no need for primer, so electrostatic painting technology helps save time and construction costs.

- High resistance to weather damage, Tanminh's aluminum profile surface is warranted for up to 25 years - Improve product quality and processing time, can be put into use in a short time but still ensures adhesion

- Diverse color palette of up to 20 paint colors, easy to choose to suit many architectural styles.

Because of these differences, Anode-plated aluminum and powder-coated aluminum are applied differently:
- Anode plating is often used in aluminum products that require high abrasion resistance such as household appliances, furniture, sporting goods, car, ship, and aviation components.
- Thanks to the advantages of diverse colors and excellent durability, powder coating is often applied in household appliances, interior and exterior doors...
