The importance of Pre-treatment before
Powder Coating

Pre-treatment creates a surface that the coating can adhere to and significantly heightens the performance of powder coating, whose purpose is to provide excellent protection to the metal being used. Pre-treatment also ensures that powder coating reduces a metal’s susceptibility to rust, corrosion, or damage, increasing its use and lifespan. 

At Dynamic Steel Coaters, we have two pre-treatment procedures: shot blasting and the seven-stage chemical treatment.

A perfect powder coating depends on a well-prepared metal surface. Pre-treatment is a prerequisite for powder coating any metallic exterior. This is because various metal surfaces are often pre-coated with dirt or oil, which prevents perfect coating. Thus, pre-treatment is crucial for ensuring long-lasting results in all cases of powder coating.

What is Shot Blasting?

Shot Blasting is a widely generic term for cleaning, smoothing, and preparing a hard surface by blasting solid particles across the surface, causing the particles to chip away the “contaminated” surface, leaving a frosted effect. The effect would be like using sandpaper that provides a more even finish and no area left uncleaned, especially in corners or small nooks and crannies.

What Are the Benefits of Shot Blasting?

Shot Blasting is a way of ridding the surface of non-eco-friendly chemicals, leaving a smooth/polished, matte surface that is environmentally safe.
The use of Shot Blasting also allows metal workers to ensure that the steel surface is free of faults or defects.

What are the most common items that are shot blasted?

Shot Blasting can be used on items that require thorough cleaning but cannot move through an acid treatment cycle or conventional cleaning techniques. More oversized items, especially of higher material thickness, can be shot blasted for optimal cleaning.
