Want to sound like an industry pro?
Here are four powder-coating terms to add to your vocabulary:
Knowing these terms will not only help you communicate effectively but also enable you to make informed decisions when discussing your project with an industry expert.
Powder adhesion refers to the ability of powder particles to stick or adhere to a surface. Proper surface preparation is essential for achieving optimal adhesion when applying a coating. Thoroughly cleaning the surface beforehand ensures that any contaminants or residues are removed, allowing the coating to adhere effectively. Additionally, the surface should have sufficient hardness and a texture that is neither too smooth nor porous.
This commonly used deposition method involves spraying charged powder particles onto a grounded substrate. The charged particles adhere to the substrate due to electrostatic attraction, resulting in a high-quality finish.
Outgassing refers to the release of gas or air that was dissolved, trapped, or absorbed in a material. The simplest way to avoid damage is to heat the part before coating it, which allows the gases to be released. Surface contamination can also cause outgassing, so it is important to ensure proper pretreatment of your parts before coating them.
Overbake is the result of curing powder coat at too high of a temperature or leaving a part in the curing oven for too long. The film can often become excessively hard, leading to potential embrittlement. Additionally, the color and gloss may be adversely affected.
