Electrocoat Process for Non-Chromate Primers in DoD Manufacturing

WP-201010

Objective

The objective of this project is to evaluate and demonstrate novel electrodeposited, non-chromate, no volatile organic compound (VOC) primer technology that is environmentally acceptable (no hazardous air pollutants, regulated heavy metals, or emerging contaminants such as Cr6+, Ni, Co, or Ce), efficient, and cost-effective.

Technology Description

Electrodeposited primers are environmentally friendly coating technologies widely used in the automotive, industrial, and structural commercial markets. These coatings are applied via an electrically assisted dip method from an aqueous media where greater than 95% of the paint solids in the bath deposit on the parts being coated. The deposition process results in complete part coverage with uniform coating thickness over both exterior and interior part surfaces. This method can handle parts from basic flat surfaces to more complex three-dimensional parts and is especially applicable for parts that have recessed areas where conventional spray coatings would be difficult to apply. Additionally, electrocoat primers are resistant to commonly encountered hydrocarbon solvents and exhibit improved reliability, safety, and extended service life.

Benefits

The electrocoat process provides consistent film thicknesses and improved paint coverage on complex parts. Additionally, utilization of an electrocoat system reduces labor requirements, lowers paint line maintenance, and improves paint line efficiency. A required modification to meet permit regulations at the Fleet Readiness Center North Island would enable full-scale production of the electrocoat process after the conclusion of the project. The non-chromate electrocoat process has the potential to be transitioned to any Department of Defense facility that paints components such as wheels and struts.
