Your choice of powder coating is essential to get the results you want. Here are some important factors to consider when making your decisions.
What Are You Coating?
Think about what metal you are coating and where the part would be used. For example, some powder coatings are specially designed to cope with high temperatures or wet conditions.
Coating Types
Different powder coatings have different benefits. Epoxy-based coatings, for example, resist chemicals well, while polyester-based powders may be better suited for outdoor use thanks to their weather damage and UV resistance. Blends can combine features, and there are also innovative options such as thermal plasma spray offered by companies such as www.poeton.co.uk/surface-treatments/thermal-metal-sprays/plasma-coatings/.
Prepare the Surface
Whatever coating you choose, surface prep is key. This might include using a type of conversion coating, degreasing or blasting. Pre-machining or an undercut process may be used to improve grip. The provision of these may influence what service provider you use.
Consider Durability
Powders have varying lifespans, and this is another important consideration. Some are better for high-traffic areas, while some will be best at resisting heat, wear or scratching.
A thicker coating does not always mean increased durability. In fact, too much coating can result in uneven curing or cracking.
Pick Your Finish
The finish you choose is important and not just because of aesthetics. A matte finish, for example, may work best when a low-shine result is required, while textured finishes can offer more grip and hide imperfections.
