You may have heard the term “powder coating” metal but do you know what it is? Powder coating is a dry powder that is heated at a low temperature to adhere and form a skin. Usually the powder is a thermoplastic or thermoset polymer that is applied electrostatically.
Many household items are powder coated: appliances, light fixtures, car parts. It is commonly used in industry for its uniform appearance and durability. Though it is also a great way for jewelers to add color and even texture to their work. For production jewelry it is ideal because several pieces can be cured at one time.
Large items like that are powder coated using a spray booth and static charge to get the powder to “stick” to the surface. Though you can also sift the dry powder onto a surface similar to applying enamels.
Once the powder has been applied it can be heated in a toaster oven to cure and flow. Do not use a toaster oven that you also use for food.
Some benefits to powder coated surfaces are:
Once heated and cooled the powder turns into a smooth “skin” like coating that is permanently attached to the surface. Unlike enamel the curing temperatures are low enough that powder coating can be applied to more than just metal. Wood and some organic items can also be powder coated. Anything that can withstand a temperature of 450 degrees Fahrenheit can be powder coated.
