What are surface treatments used for?

Surface treatments are important for prolonging the life of certain products and materials. Some of the common methods include:

Dip Coating – This is a finish that is often applied to items like tool handles. It involves heating the metal to a very hot temperature of about 250 degrees Celsius. Once it has been heated, the metal is dipped into a polythene powder. Air is passed through to help an even coat to form, dusting the hot metal and resulting in a smooth coated metal.

Powder Coating – Paint in a powder form is drawn towards an object that has been electrically charged. This helps to produce a smooth and even coating of paint powder over the surface of a material. On heating the object, the powder starts to melt, and you end up with a paint finish with no running. For more details on Surface Treatments, visit Poeton, suppliers of Surface Treatments.

There are many materials that would corrode and rust if they are left untreated. These items include lamp posts and items made from steel. Galvanising is the process used for steel to offer protection from rust. Galvanising involves dipping steel in molten zinc to provide a protective coating. This is quite an effective process and galvanised items can last for some decades before requiring a recoating.

Electroplating – This method involves applying a thin metallic coating by passing a positive charge through a solution of dissolved metal ions and a negative charge current through the metal to be plated. Virtually any base metal that are conductors can be electroplated to improve the performance.
