State-of-the-Art Enhanced Performance Pretreatment (EPP)
Preferred Powder coating utilizes a new titanium based nanotechnology conversion coating in both the batch and conveyorized paint systems. This process, known as Permatreat EPP or “Enhanced Performance Pretreatment” is a conversion coating process developed to replace the iron and zinc phosphate conversion coatings currently under scrutiny.
The EPP process allows Preferred Powder to compress the surface preperation steps into four stages; Alkaline cleaner, Rinse, EPP Conversion Coating, DI Rinse. This allows Preferred Powder Coating to meet and exceed the pretreatment needs of high performance powder products and customer specifications for multi-metal applications including all RoHS and WEEE legislative directives.
Preferred Powder coating utilizes CNC automated monitoring with real-time and continuous automatic chemical adjustment to ensure our surface preperation system is always properly balanced. Computer screens throughout the organization display the specific operating parameters of each washer stage. At the same time, the automatic pumping system maintains the preset chemical balances.
