It might seem that simply cleaning metal surfaces thoroughly should be enough to ensure good powder coating results. But while it is true that the process demands a clean surface at least, by applying a proper metal pre-treatment process the results will be at their maximum.
For many industries, lengthening the lifespan of essential machinery is a critical concern. Logically, powder coating is a time and cost-effective way of doing so. Of course, this process has to be done right to be worthwhile, which is why a phosphate pre-treatment process is considered a key element of any preservation policy.
