Powder Coated Steel Pipe

Powder coated steel pipe is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminum extrusions, drum hardware, automobiles, and bicycle frames.

Powder coated steel pipe advancements in powder coating technology like UV-curable powder coatings allow for other materials such as plastics, composites, carbon fiber, and MDF (medium-density fiberboard) to be powder coated due to the minimum heat and oven dwell time required to process these components. The powder coating process was invented around 1945 by Daniel Gustin and received US Patent 2538562 in 1945. This process puts a coating on an item electrostatically, which is then cured by heat. The finish is harder and tougher than conventional paint. The process is useful for coatings on metal used in many household appliances, aluminum products and automotive parts.

● Powder coatings contain no solvents and release little or no amount of volatile organic compounds (VOC) into the atmosphere. Thus, there is no need for finishers to buy costly pollution control equipment. Companies can comply more easily and economically with environmental regulations, such as those issued by the U.S. Environmental Protection Agency.

● Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.

Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.

● A wide range of specialty effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.

● Curing time is significantly faster with powder coatings compared to liquid coatings especially when using ultraviolet cured powder Coatings or advanced low bake thermosetting powders.
