The process involves spraying finely ground, electrostatically charged particles of pigment and resin onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces. The materials used are free of Volatile Organic Compounds (VOC’s), making the process environmentally friendly. The coated parts are then placed into a curing oven for a specific time and at a specific temperature, depending on the type of metal being coated. Curing ovens can be powered by various heat transfer technologies, such as convection, infrared, or ultraviolet. Powder coating technology is replacing liquid finishing technologies because of its durability, ease of use, and uniform application, while also rewarding its users with cost savings versus conventional liquid coatings. It has become prevalent where extraordinary coating durability is valued. Over the last 20 years, it has become recognized as a superior process and is now widely used in various industrial finishing applications. For these reasons, powder coating is the most rapidly growing finishing technology in North America. 

Sand Blasting is a mixture of water, glass,sand or soda and Environmentally friendly additives to prevent flash rusting. It’s virtually dustless and ideal for all types of metal, cast, aluminum ‎brick and concrete.

GENERAL OVERVIEW 

The entire powder coating process involves several steps:

  • a blasting, stripping and/or solvent cleaning step to insure the substrate is free of any oils, dirt, rust, mill scale, etc; 

  • a pretreatment step (an important step not done by all coaters) during which the product is treated with a pretreatment chemical or conversion coating, usually phosphate or zinc based, to further protect it and improve the surface for powder adherence; 
  • rinse, rinse, rinse…dry completely then; 

  • powder coat, usually done with an electrostatic gun, but sometimes in a fluidized bed; 
  • 
finally, FULLY cure the powder in the oven, generally at 375-400 deg. F, 15-20 minutes (varies) , making sure the oven is preheated to temp.

ADVANTAGES https://totalcoatings.com/eng/advantages/ https://totalcoatings.com/eng/advantages/#respond Fri, 24 Dec 2021 23:24:48 +0000 https://totalcoatings.com/eng/?p=49 Continue Reading ]]> Although a finish represents only one attribute of a coated part, it is the most visible and influential characteristic to the consumer. Powder coatings have a positive impact on the consumer, both directly and indirectly, and provide solutions to issues of public concern. Powder coatings have become the coating technology of choice for consumable goods from toolboxes, bicycles, office furniture, and lawn furniture to widespread markets such as appliance and automotive for the reasons listed below.

QUALITY

The unique rheological and application characteristics of powder coatings provide superior consistency and uniformity of finish without sags, drips, runs, or bubbles. They provide extremely tough, durable films, enhancing the high quality, value-added image of consumer products. In general, the performance properties, such as impact resistance, flexibility, and corrosion resistance, of powder coatings are better than with liquid paints. Powder coated parts resist cracking, peeling and marring during handling and normal service use. In many cases, merchandise is specifically being advertised as “POWDER COATED”because of the quality image it projects.

ECONOMICS

Powder coatings are frequently a cost saving alternative to liquid paints with respect to energy savings, labor costs, rework costs, material usage, waste disposal, and overall line efficiency. The advantage to manufacturers and the consumers is a coated part with a superior quality finish at a reasonable cost.

ENVIRONMENTAL

Environmental issues are of significant interest and importance to the government and general public today. Unlike many liquid paints, powder coatings are compliant with environmental regulations. Liquid paints often contain solvents, which can contribute to air pollution and, in some cases, ozone depletion. Powder coatings are free of such pollutants. Wet painting processes can generate sludge, which must be disposed of into hazardous waste landfills. Properly formulated powder coatings generate no such hazardous waste. The consumer can feel good about buying a powder-coated product, which is ENVIRONMENTALLY RESPONSIBLE.
