What is Powder Coating?
An organic powder is applied to the metal to form a coating using electrostatic attraction. The powder is then heated until it has a smooth, firm finish. Powder coating can last up to 40 years, depending on the preparation, type of coating used, components, and treatment method. Despite the fact that most powder coatings are quite durable, weatherproof, and able to sustain years of intensive use, some circumstances can significantly hasten fading and performance. A reputable powder coating manufacturer always measures the thickness of the powder before and after its curing process. Because it plays a crucial part in the effectiveness of the powder coating.
Types of Powder Coating
All of the types of powder coating fall under two categories known as polymers. One is thermoset and the other one is thermoplastic. But there are some powder coatings that are available in both thermoset and thermoplastic versions.
As we know that powder coating is a common method of metal finishing that handles a variety of product types and materials across numerous industries. You must make sure the thickness is appropriate for the task at hand as this is one essential component of an efficient powder coating. The thickness requirements can vary greatly depending on the product, but they are always a crucial component of the efficiency of the powder coating.
Determining the Thickness of Powder Coating
The thickness of optimal powder coating lies anywhere between 2 and 8 millimetres. Depending on the properties and performance requirements of the metal that needs to be coated, powder coating powder suppliers provide recommendations.
During the powder coating procedure, which makes use of an electrostatic field, products are covered with powder. The powder particles get electrically charged before they come into contact with the grounded coating components. A cohesive film that covers the entire substrate is formed when the particles mix during curing.
There are certain properties that you need to consider when measuring the thickness of the powder coating. You must consider these characteristics of the material that you want to coat:
- Range of coating thickness
- Type of coating
- The cost of equipment
- Substrate material
- Part’s shape and size
The Impact of Thickness on a Coating Durability
The thickness of powder coating can impact its overall performance, so the best thing is to understand the optimal range for your element. Thicker coatings are required for items that will be exposed to the elements or potentially corrosive conditions since they can help protect the components underneath. It is best to always follow the manufacturer’s recommended coating thickness. Because overcoating can result in delamination, improper curing, and other performance issues.
How to Make an Effective Coating Thickness?
The performance of an item is ultimately dependent on whether the coating thickness is within the supplier’s recommended range. For the product to work at its best, the coating thickness must be appropriate for the product’s shape, material, and possible applications. You can talk to the manufacturer’s helpline of customer support agents for information on the necessary film thickness.
