Also known as sandblasting, grit blasting, or media blasting.
Abrasive Blasting is used to:
1. Make a rough surface smooth.
2. Make a smooth surface rough.
3. Shape a surface.
4. Remove surface contaminants or material, like paint, rust, or residue.
5. Clean or prepare a surface for primer and final coating
How Abrasive Blasting Works?
There are typically three-part to blasting processes…
1. Abrasive container, or blasting pot
2. Propelling device or mechanism
3. Blasting nozzle
Blasting is the first step of the powder coating procedure. It means applying material (such as steel grit, garnet, etc.) on the surface with high pressure for removing all contaminations, dirt, and impurities. Blasting is by far the most efficient and environmentally friendly process of cleaning materials.
Anti-corrosion Coatings (Epoxy Primer) allow for added protection of metal surfaces and acts as a barrier to inhibit the contact between chemical compounds or corrosive materials. Epoxy Primer is recommended to all clients if products are not coated within 24 hours.
Powder Coating nowadays is slowly replacing wet paint on most metals. It means spraying electrostatic deposition (ESD) on the surface of the metal. The powder is usually applied to the metal via a spray gun which electrostatically charges the powder to attract it to the grounded part.
Baking in an oven at a temperature between 160 - 240° C. The heat causes a chemical reaction that produces long molecular chains which make the coating much more resistant against environmental disturbances. It goes without saying that the materials must be clean before starting the powder coating procedure.
