Preparation before the powder coating process is critical to the strong adhesion of the paint to the surface.
That starts with the correct abrasion cleansing application
CHEMICAL CLEANING
This is a quick way of removing all the old powder coat, paints, grease and oil
Our system involves:-
-
Dipping process item goes into our acid bath
-
Remove item from acid and clean back with water
-
Then peening if required (light blasting as required this may be because of some corrosion
-
Next over for outgassing ready for coating if required
LIGHT BLAST CLEANING
Using high pressured air thats then "blasted" through a hose this is an extremely effective method for removing debris and restoring the original substrate.
​
Light blast cleaning means using finer products to strip the material bare
​
Powders that range in diameter from 1mm to 0.1mm
HEAVY BLAST CLEANING
When a heavy piece of metal is required to be prepped then often heavy blasting will be needed.
​
Heavier products are used as the "blast" such as shot, glass, sand and many other depending on the finish required.
​
When the pat is blasted a blast profile is created whihc helps adhesion.
OUTGASSING
To prevent tiny pinholes appearing in the finished coating we "gas out" the part.
​
During the casting process gasses can become trapped
​
This process involves heating to essentially expel any gasses that may exist within the metal that will interfere with the powder coat as its curing under heat.
