WHICH MATERIAL CAN BE COATED?
Powder coating can be used to coat many types of materials. The most common material is metal, but you can also powder coat wood, plastic, composites, glass, and MDF.
Powder coating can be used to coat many types of materials. The most common material is metal, but you can also powder coat wood, plastic, composites, glass, and MDF. The first consideration for coating objects besides metal, is can it withstand the temperature. Most plastics will melt when subjected to 400 degree heat for any length of time so it is important to research exactly what your object is made of before you try to powder coat it. During the powder coating process of metal, the powder is electro-statically attracted to the metal when it is grounded.
The problem that arises when powder coating other materials, is that they are not electrically conductive. If you were to spray powder on these materials, the powder won't stick. Preheating is required to coat these materials. This method requires the object to be heated before the powder is applied. As the powder touches the heated object, it will slightly melt on contact, which is how the powder sticks. Once the powder has been applied, the object will be put back into the oven and cure. Powder coating is economic and useful technology for most of materials. Application area is wide and equipment of powder coat is easily accessible.
