Conductive primer AEROCRON®

coatingcorrosion protectionspray

Product overview
AEROCRON® electrocoat primer is PPG's chrome-free, water-based electrocoat primer formulated for aerospace applications. It provides adhesion and corrosion protection for common aerospace substrates and is compatible with industry-standard pretreatments and topcoats.

Substrates

• Aluminum alloys: 2024, 2050, 2214, 5083, 6056, 6061, 7075, 7175 and AS7G
• Titanium
• Stainless steel

Application and process

• Electrocoating (electrically driven dip) enables coating of conductive aircraft parts, including recessed areas, and eliminates overspray compared with spray processes.
• Precise film-thickness control ensures uniform coverage on complex geometries, reducing runs, drips and sags.
• Thermal cure cycle enables immediate handling of fully cured parts.
• Process can be automated and integrated into closed-loop lines to minimize waste and labor.

Environmental considerations

• Chrome-free, water-based formulation.
• High transfer efficiency: approximately 90–95% material usage.
• Low VOC: below 150 g/l.
• Near-zero waste discharge due to closed-loop electrocoat process.

Performance

• Provides corrosion protection and improved topcoat adhesion for durable aircraft finishes.
• Designed to deliver barrier and corrosion-resistance properties.
• Qualified to SAE/AMS-3144.
• Weight-saving properties that can contribute to reduced fuel consumption compared with traditional spray primers.

Health, safety and productivity benefits

• Chrome-free and low-VOC formulation reduces worker exposure to hazardous substances and lowers fire risk.
• System operation and maintenance can be performed by a single operator; supports non-uniform line loading where applicable.
• Immediate part handling reduces cycle time and paint waste.
