Powder coating is a technique that is used to apply a protective coating to metal. Compared to other coating techniques, it has many advantages, such as creating a very smooth and even finish that resists corrosion. As a result, powder coating has applications in a wide range of industries. Here are a few of the most important.

1. Vehicles

Many people choose powder-coated rims for their cars because they like the appearance of the wheels being treated with this method. Powder coating for rims also protects wheels against environmental damage, for example from rain, snow, salt or loose pebbles on the roads.

Powder coating is also used to protect other parts of a vehicle, such as door handles and bumpers. Vehicles with trims that have been treated with this technique often hold their value better than ones without them.

2. Medical Devices

Powder coating is used to make medical devices that are smooth-surfaced, and therefore, easy to clean. As a result, this technique can help to reduce the risk of hospitals passing infections between patients. Surgical tools are powder-coated to ensure they adhere to the highest standards of hygiene, with no ridges or pits that bacteria can hide in.

One particularly important medical application of powder coating is the coating of implantable medical devices. Smoother surfaces on these devices help to reduce the risk of a blood clot forming, which means that powder coating can literally save lives.

3. Home Appliances

Powder coating is used in appliances that have metal surfaces that are frequently exposed to heat and water, such as washing machines and dishwashers. Without the powder coating, these appliances would be very vulnerable to corrosion and would break down much more frequently. Powder coating ensures that all machines produced by a manufacturer meet production standards and are able to perform well throughout their warranty period.

4. Pharmaceutical Products

Although metal powder coating is the most well-known form of this technique, it can also be used with polymers. One of the most interesting applications of polymer powder coating is in the production of pharmaceutical products. Chemists use powder coating to apply protective coatings to pharmaceuticals, allowing them to have much longer shelf lives than would otherwise be possible. Medications treated with polymer-based powder coating are also able to withstand a much larger range of conditions, which means that they can be used and stored in a much wider range of settings.
