Surface finishing is a critical step in the manufacturing of products, as this top layer is what lends your final products their visual appeal as well as a degree of resistance to various elements that could cause premature degradation to their surfaces. Thus, while paint was a popular way of finishing products in years past, there has been a steady shift towards powder coating over the years, as more and more industrialists realise the host of benefits that this finishing technique offers.

However, simply because you have selected powder coating as your finishing technique does not mean you can choose any resin for the job. The various options available are endowed with unique attributes, so your choice should be dependent on what type of reaction you want for your products. To help you discover the array of available options, here is a simple guide to powder coating resins.

Hybrid resins

In the beginning, epoxy resins were the go-to solution for industrialists opting for powder coating as their preferred finish. And while epoxy does offer superior chemical resistance, the main noteworthy drawback of this option is its ultraviolet instability, making it unsuitable for products that are primarily employed for outdoor applications. Polyester, on the other hand, is a resin renowned for its robust adhesive properties. However, its main disadvantage is the lack of chemical resistance. To get the best of both worlds, you can use hybrid powder coating resins.

Comprising both polyester and epoxies, hybrid resins are a great option for industrialists that are manufacturing products that will be exposed to extreme environments, as the hybrid powders lend the items enhanced chemical and mechanical resistance. Admittedly, the hybrid variety does cost more when compared to other powder coating finishes. Nonetheless, it is a worthwhile investment since it will lend your products unparalleled longevity.

Nylon resins

If you are manufacturing products that will be put through high usage in extreme environments, you should consider nylon resins for your powder coating finishes. This resin is considered to be one of the most protective options you can choose, and this can be attributed to the numerous ways it safeguards your finished products.

Not only does this resin have high thermal stability, making it ideal for use in hot environments, but it also offers chemical resistance, mechanical resistance and reinforced physical stability. These characteristics ensure nylon resins can withstand virtually anything they are exposed to. It is also worth noting that nylon resins can also withstand friction while remaining resistant to abrasion, making this an ideal choice for coating moving components.
