Your old piece of metal is out of tune and needs to be freshened up a little bit A new powder coating is required to give the piece new life. But before you head towards this method, you might have seen pros working on sandblasting too. These two terms, namely sandblasting and powder coating, are completely industrial base and newbies will find it hard to understand the same. It is really important that you get to learn about these options first, before you finally plan to use them right away.
What Is Powder Coating?

| Sandblasting And Powder Coating |
Powder coating is primarily defined to be a form of coating, which is applied as dry and free-flowing powder. The powder comes out at a high speed in a jet stream. This makes the surface of the metallic piece smooth. The primary difference between powder coating and conventional liquid paint is that the first one is not in need of any solvent for keeping the filler parts and binder in liquid suspension section. The coating over here is mainly applied in an electrostatic manner and then cured just under heat to allow forming a skin.
- The powder over here is mostly thermoplastic or even a form of thermoset polymer. It is mostly used for creating a hard finish, proven to be tougher than any of the conventional paint.
- Powder coating is widely used for coating metals like aluminum extrusions, household appliances, bicycle parts, automobile spare parts and even drum hardware.
- Some of the newer technologies will help to introduce other materials like MDF in sandblasting and powder coating to be powder coated in nature with the help of various other methods.
The Idea Of Sandblasting:
Sandblasting is mainly a form of metal preparation and part of sandblasting and powder coating process, where some of the fine bits of materials like sand will be propelled right at high velocity for cleaning or just etching any surface. Sand blasting does not need to be done with sand but is also done with other abrasive material. These are coarse pieces of jet stream sprayed onto the piece. Whenever the term talks about sand as the main material, other uniform and smaller particles like the walnut shells and silica sand can also be seen used mostly these days.
- These sandblasters are designed to use pressurized gun for producing of the high powdered pressure to shoot out the sand particles towards any metal surface at faster pace.
- This is a high and fast pressure movement, which will make sandblasting quite an effective option in just removing all forms of dirt on any metal surface.
Types Of Sandblasting Methods:

You might know that sandblasting and powder coating can be stated as two of the major parts of the industrial area, especially while dealing with metallic objects. Most of the time, sandblasting usually take place before hitting the powder coating process. After the coating the painting becomes really easy. The surface is smooth and shiny. There are multiple sandblasting methods readily available for you to understand.
- The first one is the silica sand, which is also termed as silicon dioxide. The idea of silica sandblasting of sandblasting and powder coating is a common method used for removing impurities from surfaces. It is mainly because these particles are of same size and edges are quite sharp.
- Another option to consider got to be the soda sandblasting. Here, baking soda is used in the present blasting procedure. Soda is primarily used as abrasive for removing rust from metals without damaging or depressing metal under the rough patch of land.
Apart from the methods stated there are some more available like steel grit, glass bead and so many more. It is always recommended to log online and get help from pros in order to learn more about the sandblasting and powder coating practices. The more you learn, the better you will get to understand the value of industrial uses of sand blasting lately.
