Demo-Xearch-XYZ is pleased to offer our powder coating capabilities – a beautiful, and extremely durable finish on all metal fabricated products including custom casters. What is Powder Coating? Powder coating is a type of coating applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or thermoset polymer . Advantages: Powder coating emits zero or near zero VOCs (Volatile Organic Compounds – bad for the atmosphere and your health!) Powder coating produces a much thicker, tougher coating than conventional paint. Powder coated surfaces have fewer surface defects, such as sags and runs. How does Powder Coating Work? Powder is applied to a part through electrostatics: The spray gun imparts a positive charge to powder. Parts to be coated are electrically grounded. The difference in electrical charge attracts powder to part. Powder builds up on the part until the electric charge is fully insulated from the layer of powder. Once the part is covered in powder it is placed in an oven to cure The powder melts into a uniform film and cures into a hard, solid surface. All booths and ovens are 30 feet long x 10 feet wide x 10 feet high The oven operating temperature up to 500°F Parts can be coated in over 6,500 different colors! Attractive and durable, finished parts are removed from the oven and ready to be shipped once cooled.
