Spray Pretreatment Powder Coating Line
| Part preparation processes and equipment | ||
| Purpose | Process | Method |
| Remove oil, soil, lubrication greases, metal oxides, welding scales etc. | prior to the powder coating process | a variety of chemical and mechanical methods, depends on the size and the material of the part to be powder coated, the type of soil to be removed and the performance requirement |
| cleans and improves bonding of the powder to the metal and avoid the use of chromates, which can be toxic to the environment. | degreasing, etching, de-smutting, various rinses and the final phosphating or chromating, against corrosion and adhesion of the powder. | Chemical pre-treatments involve the use of phosphates or chromates in submersion or spray application |
| In many high end applications to get high end performance characteristics | following the pretreatment process and subsequent to the powder coating application. | the part is electrocoated , This has been particularly useful in automotive and other applications |
| Blast media and blasting abrasives are used to provide surface texturing and preparation, etching, finishing, and degreasing | prior to coating. The most important properties to consider are chemical composition and density; particle shape and size; and impact resistance. | abrasive blasting or sandblasting and shot blasting. |
