Prior to paint or coating application, it is important that the parts are prepared for the best possible adhesion. This is achieved through pretreatment processes where parts are treated using degreasers, cleaners, and rinses that eliminate contaminants. In many cases the parts are then coated with anti-corrosion protection by means of chemical agents or nanotechnology.
Our pretreatment systems come standard with the following features:
- Stainless steel tanks and housing
- Pretreatment entrance and exit vestibules to control the air flow and eliminate potential hazardous air leaks into the workplace
- Double welded storage tanks made of carbon or stainless steel
- Directional nozzles with sphere-type adjustment
- Tanks with drainage system
- Standard controls with control panel based on PLC
- Gas train, control thermocouples, thermometers, and manometers
The are two different types of pretreatment processes. The two basic ones are zinc phosphate and iron phosphate. Zinc phosphate is the most corrosion resistant process, but the most difficult to control. Iron phosphate is noted for good corrosion resistance, but it does not obtain the same resistance as zinc phosphate. Over the years, new technologies have emerged, which help become these processes environmentally friendly.
