If you are planning on powder coating your custom fabricated products, you should have the protective layer applied by an experienced industrial expert. In general, powder coats are durable and will provide prolonged protection to metal goods. However, if the coating is applied incorrectly, it could fail prematurely, leaving the metal vulnerable to the elements. Therefore, engaging a qualified fabricator for the finishing work will guarantee the best results. If you are set on conducting the powder coating work onsite, you should consider the tips below to prevent failure.
Select the Best Powder
You should evaluate the different powder coating products on the market and choose the most suitable for your needs. In general, the right choice will depend on factors such as desired durability, colour, fabricated metal and coating properties. For example, epoxy powder is an ideal choice if you are looking for an impact-resistant option with exceptional protection against corrosion. However, it is unsuitable for outdoor use due to UV radiation. Polyester has excellent outdoor performance and good all-round characteristics. Acrylic powder is suited for creating clear coatings.
It is important to compare the options and choose the most compatible product for optimal durability.
Cure for the Recommended Period
Your powder coat can fail if you do not cure the finish correctly. This deterioration will occur even if you select the best coating material. It is important for you to follow the manufacturer's recommendations on the curing process, temperature settings and the curing time for ideal results. You should note that when curing for a shorter than required period, the powder will not be distributed evenly and the coating will not stick to the surface. On the other hand, over-curing will damage the powder resin, compromising its resilience. Following the instructions provided will guarantee prolonged service, better aesthetics and exceptional product performance.
Prepare the Surface
You should prepare the metal surface with care before applying the powder coating during the finishing process. If the plastic cannot adhere to your custom fabricated products, the coating will chip easily and delamination might occur. You should note that powder coats do not adhere well to smooth surfaces. Therefore, you should plan on texturing your products during the preparation period. For example, you can use an abrasive blasting technique or chemical treatment to create the best surface for finishing.
Powder coating is a challenging process, and the premature failure of the protective layer will translate into unexpected costs. Therefore, you should plan for professional finishing of your metal products for the best results.
