Why Powder Coat
What is Powder Coating?
Powder Coating is the application of organic powder by electrostatic attraction to metal. Once cured by heat the finish is a smooth, hard skin. All processes are factory applied under controlled, stable conditions. This provides significant benefits over traditional wet painting” – Patrick Handlovsky, TIGER Drylac Canada Inc
Why Powder Coat?
Top 5 Reasons to Powder Coat Your Products:
- Durability – Thermal bonding process used in powder coating makes for a much more durable finish than wet spray paint. This bonding process creates a virtually unbreakable sheet of protection upon the surface of the parts. Powder coating generally produces a coating twice as thick as standard paint. The real advantage is its flexibility and ability to bend and yield with the material it is applied to.
- Cost –The economic benefits of powder coating are numerous but the largest benefit has to do with efficiency and overspray. The average transfer efficiency of powder coating is 60-70% and any over spray is a solid and can be reclaimed and re-used netting virtually no wasted product. With liquid paint you have a transfer efficiency of 30-35%, roughly 50% of the product is evaporated and there is no possibility of reclaiming over spray. With less waste over spray and less risk for runs and other defects, powder coating has become even more cost efficient. The base product for powder coating is also substantially cheaper than wet paint.
- Speed – The main advantage from a production point of view is that when the powder coated product comes out of the oven it is completely cured once it has cooled to ambient temperatures and ready to be put to work. Standard liquid paints can take days to completely cure and depend on the atmospheric You can literally put a powder coated object to work as soon as the part is cool enough to touch.
- Colors and Textures – A large array of specialty effects, textures, colors and designs are accomplished through powder coating with ease, including effects that would otherwise be near impossible to accomplish through conventional liquid coating. Virtually any variation of color on the spectrum can be found in powder form. A constantly increasing variety of textures, wrinkles, veins and hammertones are available. Veins and hammertones are textures of alternate colors that appear throughout the part. effects that would near impossible to accomplish through conventional liquid coating.
- Environmentally Green – The powder granules are not a significant health, fire, or environmental hazard. In its dry form, it’s called a nuisance dust largely because it will make a dusty mess if it gets spilled. The waste isalso not hazardous and can be disposed in the landfill. It has virtually no volatile organic compounds (VOCs), it’s non-flammable, and is non-carcinogenic. Compare that to wet automotive paint which is flammable, carcinogenic, and full of VOCs. Wet paint contains harmful chemicals (VOCs) that have been proven to deplete the ozone and produces hazardous waste that needs to be disposed of in an appropriate and costly manner. Though, safely applying powder coating requires precautionary measures to avoid breathing in the powder and getting it on your skin; this is an easier task to manage since the product is a solid and inert (it doesn’t pose a health risk when not being sprayed). Powder coating uses an air gun to blow away misapplied uncured powder opposed to the chemical thinners that wet spray paints require to clean up, or fix, application errors.
The Future of Powder Coating
The global powder coatings market is expected to reach $12.48 billion by 2020, according to a new study by Grand View Research, Inc. Growing support for the use of powder coatings in comparison to conventional liquid paints by regulatory agencies such as EPA and REACH on account of negligible VOC emissions is expected to be a key driver for market growth. In addition, growing application demand with regards to automotive, appliances and consumer goods is also expected to drive powder coating sales over the next six years.
The powder coating market presents a rapid annual growth of around 6% from 2012 to 2018. Currently, the industrial uses are the largest application market of powder coatings. Automotive industry experiences the most dynamic growth. Steady and strong growth is also expected by furniture and appliance markets. Furthermore, the application of powder coatings in IT & Telecommunication is also being widely explored
