Chemical Bathing Metal

What is a chemical bath?

Metal surfaces must be cleaned by a chemical bath for a finish to be successfully applied. Prior to powder coating, all foreign matter must be removed for adhesion to occur with a smooth coat.

Examples of debris requiring cleaning

  • Dirt
  • Oil
  • Grease
  • Scale (Metal Salt)
  • Particulates
  • Stencil Markings
  • Dust
  • Oxides, hydroxides and carbonates of Fe, Mg, Ca, Zn, Cu and Mn. For example, these can be geothite FeOOH and haematite Fe2O3
  • Sulphates of Mg and Ca
  • Phosphates of Fe, Mg and Ca. (hydroxyapatite (Ca3(PO4)2; Ca(OH)2)
  • Sulphides of Zn, Cu, and Fe
  • Silicates (acmite Na2O; Fe2O3; 4SiO2)
  • Mineral and animal oils and fats
  • Algae and slime found in cooling water circuits
  • Heat denatured product
  • Polymers and hydrocarbons formed in various process streams

Cleaning & stripping metal

A combination of chemical reaction, detergency, mechanical action and solvent dissolution helps achieving effective surface cleaning of various metals. The main methods employed in cleaning metal parts include soak, electrolytic and spray.

Chemical baths for cleaning metals come with a number of advantages. The greatest advantage is that the metal surfaces are easy to be cleaned making them ready for powder coating.

Metal surfaces get typically both inorganic and organic substances deposited on it. These substances are removed in a five step process depending on the nature of the deposits.
Cleaning & stripping metal continued
The cleaning processes of metal surfaces include hot alkaline detergent cleaning, solvent cleaning, acid etch, and electro cleaning. The water break test is the most common industrial test for metal cleanliness.

This test involves thoroughly rinsing of the metal surface that is then held vertical. Oils and other hydrophobic contaminants allow the water to rapidly drain, because it beads and breaks up. Perfectly clean metal surfaces will retain an unbroken sheet of water that does not drain off or bead up because they are hydrophilic.

First of all, our powder coating services allows us to add color to any metal surface! Such as, architectural structures, fences, furniture, wheel rims, etc. Therefore, if it is made entirely of metal, or the non-metal parts can be removed, it can be powder coated! Secondly, we provide chemical bathing to ensure removal of small particles, such as dust and various dirt, on the metal that may cause the powder coating not to adhere smoothly. Also, this cleans and strips the metal of remaining debris that may be on it prior to applying the paint. Thirdly, cleaning the metal is important for everything. Fourthly, metal collects tons of different debris. Fifthly, you want your metal to coat smoothly. Also, you want your coat to stay adhered to your metal. Therefore, clean your metal. In conclusion, you should get your metal bathed before powder coating it.
