Powder-coated aluminum is a process that creates a durable, protective finish on metal surfaces without using solvents. Polymer granules (polyester, polyester-epoxy, or fusion-bonded epoxy and acrylics) are mixed with pigments and other powder ingredients, then heated in an extruder. The extruded mixture is rolled flat, cooled and broken into small chips that are milled to a fine powder and sprayed onto the surface with an electrostatic gun. The gun imparts an electric charge on the powder, which is then sprayed to the frame, attracting the “paint” particles into every crevice. When the frame is heated, the powder melts and forms a hard, protective coating creating a continuous, seamless application.
Like any fine-painted surface, such as an automobile, routine washing with mild soap (pH:neutral) and a non-abrasive cloth or sponge, and clear rinsing will keep your painted furniture looking new. We recommend you provide extra protection with a regular application of a reputable automobile wax, which will actively repel the accumulation of moisture and water spots and minimize stains from mustard and red wine. First, rinse with a hose to remove salt accumulation, then apply wax per manufacturer’s instructions. Never use abrasive or aggressive solvent products on aluminum.
