SUPERIOR CORROSION AND UV PROTECTION GUARANTEED

E-Z-GO provides the highest quality products, and the attention to detail can be seen in even the smallest of parts. Let’s take for instance Electrophoretic Painting, also known as E-coating, which is the process of vehicle body painting utilised by E-Z-GO to prevent rust and corrosion.

The benefits of E-coating speak to the quality of our products:

• Class-leading durability
• 100% coverage of complex parts
• Superior corrosion protection
• Improved reliability for vehicle & components

 

Let’s get technical…

In simple terms, E-coating, is a process of vehicle body painting that prevents rust and corrosion. But to really explain the process, we need to get a little technical.

 

E-coat

E-coat is applied by immersion in an aqueous bath of electrophoretic paint. The paint gets charged cathodically and seeks a ground, which in this process is the part to be coated. Cathodically charged paint covers virtually every surface of the grounded part. It gets into every nook and cranny and it coats every surface. A characteristic of e-coat is the amount of film build possible. E-coat typically provides a very even-thickness film that tops out around 1.2 mm. The resultant coating gives good corrosion resistance, usually up to about 750 hrs salt spray if the metal has a good pretreatment. So, to summarise, e-coat gives excellent overall coverage at a relatively thin film with excellent corrosion resistance. The electrode position continues until the desired level of coating thickness is achieved, which can be regulated by increasing or decreasing the voltage level. The coated substrate is then cured in an oven to promote cross-linking.

 

Powder coating

While e-coating is considered to be a “wet” process, powder coating involves the application of a dry powder consisting of a precise combination of epoxy resins and various curing agents. A spray gun is used to electrostatically apply the particles onto the surface of the substrate. The fact that the particles are electrically charged is what causes them to adhere to the surface. Curing is also used as the finishing step in the powder coating process. Curing causes the particles to melt and also serves as the catalyst for a chemical reaction that produces the desired finish.

 

When do we use E-coating?

Because of the e-coating’s application, it is typically the better option when coating parts that contain hard-to-reach areas. That’s because the immersion of an object into a liquid promotes a more even and thorough distribution of the coating than can normally be achieved with a spray gun. The powder coating application process also tends to produce a thicker coating.

In contrast, the e-coating process provides greater ease of regulation of the thickness level — it’s much easier to produce a thinner coating with e-coating than with powder coating. These two advantages are particularly important in the auto industry, where an e-coating is typically applied as a primer coat prior to painting for increased corrosion protection.

 

We use Powder coat over E-coat

E-Z-GO utilises an e-coat/powder coat process to achieve superior durability and resistance for our metal frames and components. As a result, powder coating over e-coat provides exceptional benefits to your metal products, such as:

• Durability:

When you add inner e-coating to your powder-coated products, you’ll ensure they last longer and stand up better to harsh environmental conditions. E-coating is known for its exceptional durability. It resists both outdoor elements and indoor factors like household chemicals. This outstanding performance makes it an increasingly popular choice as an added layer in powder-coated applications.

• Coverage:

E-coating is the better option of the two for accessing hard-to-reach parts within your metal products. However, you might still want to add the decorative touch of powder coating. For a combination of looks and all-encompassing coverage, you can have your product e-coated, cured and then powder coated for a stylish finish.

• Corrosion and UV protection:

E-coats are known for their superior corrosion resistance, which is one of the main reasons why so many companies choose the process for industrial applications. However, since most e-coats are not UV stable, they are most often used only as primers or finishes. Pairing your e-coat with a top layer of UV-resistant powder coating ensures both the corrosion protection of e-coats and the UV protection of powder coating.

• Longevity:

When you add inner e-coating to your powder-coated products, you’ll ensure they last.
