Part preparation processes and equipment
Purpose	Process	Method
Remove oil, soil, lubrication greases, metal oxides, welding scales etc.	prior to the powder coating process	done by a variety of chemical and mechanical methods. The selection of the method 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 of the finished product.
The pre-treatment process both cleans and improves bonding of the powder to the metal.Recent additional processes have been developed that avoid the use of chromates, as these can be toxic to the environment.	multiple stages and consist of degreasing, etching, de-smutting, various rinses and the final phosphating or chromating of the substrate. Titanium zirconium and silanes offer similar performance 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
Another method of preparing the surface. Blast media and blasting abrasives are used to provide surface texturing and preparation, etching, finishing, and degreasing for products made of wood, plastic, or glass.	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.
