What is E-Coating ?
Despite having been proven and is well documented to as a high quality and durable treatment for steel, the E-coating process is still relatively unknown.
E-coating is a technique which is used in the manufacturing industry to protect steel from rust and dramatically reduce the chances of corrosion.
This technique involves immersing the part in a bath of water-soluble paint while being connected to an electrical power source set at certain voltage.
During this immersion the suspended paint particles are attracted to the item and are deposited uniformly across the body producing a smooth, durable, protective finish.
E-coating makes it possible to obtain a high level of protection against corrosion and is largely an automated process.
Why do we use E-coating?
Many industries have made use of E-coating since the 1970′s to add a level of corrosion protection to metal parts.
One of the main industries which make use of the benefits of E-coating is the automotive industry which use this process to add a protective, corrosion resistant base layer to metal bodies before final painting.
To create an extremely durable and corrosion resistant finish we recommend using a powder-coated finish applied on top of the an E-coated base. As well as the car industry, E-coating is used for domestic appliances and also urban street furniture.
- Perfect coverage and tough coating on all areas including corners and edges which are normally susceptible to chipping and flaking.
- Better coverage which and less chance of defects.
- Protects both the outer and inner edges of the products.
- Resistance to salt water spray
- Can be applied to all metals.
Sino Concept uses the same E-coating process as the automobile industry. Just take a look at how well modern cars resist rust and corrosion to see the effectiveness of E-coating.
E-coating or galvanizing?
So why should you choose E-coating over the more traditional option of hot-dip galvanizing? E-coating offers many advantages over hot dip galvanizing including.
E-coating is cheaper and more cost effective than hot dip galvanizing and offers a smoother finish with less chance of defects. What’s more E-coating offers an uniform coating with an equal layer across the length of a product, where as hot-dip galvanizing may have varying thicknesses.
Not only is an E-coated product as durable as a hot-dip galvanized one but with an attractive powder coated finish will offer more protection and could still cost far less!
