Powder coating is typically seen as the most efficient and cost-effective way to give industrial parts a high-strength, long-lasting surface finish. The durability of the finish combined with the efficiency of the process make powder coating the most suitable method for a wide range of industrial products.
However, for complex parts with difficult-to-reach areas, the liquid immersion process of e-coating more easily achieves full coverage. That’s crucial because if even a small area of a part is left uncoated, corrosion can form on the underlying metal..
At Winona Powder, we specialize in both powder coating and e-coating services. Offering these two processes means that we can combine the advantages to achieve even higher consistency and corrosion resistance than either method offers on its own. By using e-coating as a primer, we ensure complete uniform coverage of the part, simultaneously enhancing its resistance to corrosion. Then, we apply a powder coat over top of the e-coat to maximize durability and longevity.
Below, we delve further into the advantages of powder coating and e-coating when combined into a truly high-performance finish.
For complex parts with difficult-to-reach areas, e-coating can more easily achieve a full coat than other finishing methods. As such, e-coating is ideal when applied as a durable primer layer for powder coated parts that demand the utmost in coverage. The liquid immersion process makes e-coating an exceptional primer, as it’s easier to achieve a thin, even layer throughout the entire part. In turn, that ensures both durability and consistency of the powder coating process to follow.
Achieves a smooth, and more even appearance for precise aesthetic finishing requirements.
Easier to achieve uniform coverage for smaller or more complex parts with tight spaces, especially within small recesses or cavities.
Allows for more precise control over the coating’s thickness, better suited for parts requiring ultra-thin finishes.
Powder coating creates a high-strength finish that is resistant to chipping, scratching, fading, or general wear compared to liquid paint options. This enhanced durability makes it ideal for hard use applications and industrial parts where the end products are subjected to harsh environments, tough operational conditions, or frequent handling. With an e-coat primer, we can ensure maximum powder adhesion and even longer-lasting durability.
Powder coating likewise offers excellent protection against chemicals, corrosion, and the ingress of environmental elements. However, the uniform coverage achieved by e-coating can be even more effective in this respect. By combining the two processes we ensure no portion of any part surface is left uncovered, simultaneously giving you the unique protective advantages of both powder coating and e-coating.
