PowerCron 8000HE (High Edge Build)

POWERCRON 8000HE is PPG’s eighth generation cathodic epoxy electrocoat technology modified for maximum edge coverage. This product demonstrates several improvements over previous generations including excellent corrosion resistance without the use of heavy metals, improved transfer efficiency, reduced cure temperature, and reduced volatile emissions.

8000HE was developed to provide superior corrosion resistance without the use of heavy metals in the formulation, particularly lead.  The resulting product is free of heavy metals in the coating film and also any effluent that is discharged from the system.

POWERCRON 8000HE exhibits one of the highest transfer efficiencies available in a high performance cationic epoxy electrocoat.  This was achieved through a reduction in the amount of cure by-products from the coating, or weight loss, during the curing process.

POWERCRON 8000HE is formulated with a low organic solvent content, resulting in a Volatile Organic Compound (VOC) content of less than 0.1 pounds per gallon.  In addition, this product is formulated with HAPs- (Hazardous Air Pollutants) free solvents.
