Advantages of powder coating over wet painting
Powder coating is an electrostatic application of powder to metal parts. It is a widely preferred finishing process due to its ability to produce durable and affordable finishes in various colors to the surfaces. This method of producing a protective and decorative finish has evolved to become one of the most popular finishing processes in recent times.
Powder coating uses resin and fine pigment particles powder and has several advantages over wet paint. While both processes serve the same purpose, powder coating applies to more products.
What are the advantages of powder coating over wet painting?
- Powder coating is unaffected by; Chipping, Fading, Wear and tear, Corrosion, Weather, Chemicals, or Scratching.
- In comparison to wet paint, powder coating gives a more appealing finish. Moreover, powder coating produces a uniform coating layer on the metal surface.
- The powder coating process needs minimal intervention, unlike wet painting. However, Powder coating has less waste disposal costs, lower energy costs, and fewer reject rates leading to fewer operational costs.
- Wet paint has volatile organic compounds and contains carcinogens; This imparts on the surrounding. On the flip side, powder coating is not harmful to the atmosphere, plant, or shop, and people dealing with the curing process.
- Liquid painted surfaces take days to cure, unlike powder-coated products, which take a maximum of one hour.
- Powder coating equipment is energy efficient as opposed to equipment used in the wet painting process.
All in all, Powder coating can produce a thicker coat than wet paint coating. Due to these features, the powder coating process is preferred (for curing surfaces such as electrical, construction, heating appliances, to mention but a few) to wet paint. However, it is vital to use the best-quality and reliable powder coating ovens to provide the required results.
What to consider when buying a powder coating oven
- Oven size required: Your productivity depends on the size of the oven you buy. Nonetheless, a small oven can help save money. At the same time may reduce productivity. Thus, after identifying your market, you should very concentrate on knowing the optimal oven size.
- Technology: Powder coating ovens come in infrared and conventional technologies. The infrared ones are gas or electric-driven. Therefore, when selecting an appropriate curing oven, you require to consider each type’s benefits. For an ideal judgment, always contact the powder coating oven supplier to know about the product.
- Air Velocity: When you decide to purchase an oven, ensure that the air velocity is not very strong. A high air velocity can powder off the parts, making them come into contact when stored.
- Certification: You should always acquire an oven from a certified supplier; This ensures that the curing oven is of the right quality.
- Controllers: Powder curing ovens may have analog or digital controllers. The controllers assist in adjusting temperatures. You should decide on which type of control you desire to have.
