It is the process of applying a liquid coat to the part or object to be coated. The material is heated until it is a powder. It is then applied using a sprayer. The powder then hardens and bonds to the part, creating a finish. It is a method that uses fewer solvents than other types of coating. However, this method creates problems for some people.
What makes powder coating a better investment than wet paint?
Powder coating has a number of benefits over conventional paint when it comes to coating metals and plastics. For one, powder coatings produce a much higher degree of corrosion resistance than conventional paint. This is especially true of galvanized and Galvan sealed steel and aluminum, which are common metals used for automotive and architectural purposes. Paint that gets wet and then dries can corrode metal and wood, making them susceptible to premature deterioration. With a powder coating, there is virtually no chance of this happening.
What Finish Do You Need?
The type of powder used to coat the surface of a part will determine whether it requires a high gloss or a matte finish. High-gloss powder forms a shiny finish that is easy to clean. Matte finishes are generally darker and more durable and require a dry powder for best results. High-gloss powder is most commonly used for small parts while matte powder is usually recommended for large parts. There is also a process called chemical conversion that can be used to create different finishes.
What Size Powder Coating Oven Is Right?
The best size oven for powder coating depends on the volume of products you will be coating. If you are using small parts (one-piece models), a smaller size oven will work better. However, if you are coating large numbers of pieces (multi-piece models), a larger oven is needed to accommodate the greater surface area.
The size of the oven will also affect your powder coating process. Smaller sizes are used for parts that will not require more than one layer of powder. Larger sizes are used for parts that will require multiple layers of powder. The smallest size is used for parts that need to be completely covered with powder.
What Size Powder Spray Booth Do You Need?
If you’re spray coating, you’ll need to choose a powder spray booth. The size of the booth will depend on the thickness of your powder coatings. A small booth will be best for thinner powders, while larger booths will handle thicker coats better.
You’ll also need to factor in how much time and effort it will take to set up the booth. The last thing you want is for your shop to become a powder explosion. So don’t underestimate the importance of having a powder coating booth. It’s a good investment for your business.
Powder Application Problems
There are several ways to apply powder. Many people use electrostatic charging to get the best adhesion. This method requires charging tools with a positive or negative charge, such as a charge plate, a triboelectric tool or even a hair dryer. If you do not have access to one of these devices, then using a static dissipative powder and a spray bottle will give similar results. Spray the powder onto the article being coated and allow it to flow and settle. The longer you wait, the more the powder will settle. This can also be done on a belt. A powder coating equipment specialist can help answer any questions you have.
