JBA upper control arms are not finished with standard paint. We use a multi-stage industrial powder coating system designed to deliver superior corrosion resistance, coating adhesion, and long-term durability in harsh off-road and road salt environments. While we use Tiger Drylac Bengal Red powder coating as a top coat, JBA’s process goes far beyond a basic paint or single-step powder coat.
Industrial Powder Coating Process for JBA Upper Control Arms
JBA steel upper control arms go through a 10-stage paint preparation and powder coating process. Each step is designed to properly prepare the steel, prevent corrosion, and ensure the coating bonds correctly for long-term performance. This process is used to protect upper control arms from rust, chipping, peeling, and premature coating failure.
JBA 10-Stage Paint Preparation and Coating Process
1. Inspect and Bead Blast
Each upper control arm is carefully inspected and bead blasted to remove surface impurities and create a uniform surface for proper coating adhesion.
2. Alkaline Clean
An alkaline cleaning solution removes oils, cutting fluids, and manufacturing contaminants left on the steel during fabrication.
3. Post Alkaline Flush
Residual cleaning agents and loosened debris are flushed away to prevent contamination during later stages.
4. Iron Phosphate Treatment
The steel is chemically treated with iron phosphate to improve coating adhesion and increase corrosion resistance.
5. Post Phosphate Flush
Excess phosphate residue is rinsed off to ensure an even and consistent surface.
6. Final Phosphate Rinse
A final rinse prepares the surface for purification and sealing.
7. Reverse Osmosis Rinse
Purified reverse osmosis water removes minerals and contaminants that could negatively affect coating durability.
8. Final Seal
A sealing treatment is applied to prevent flash rust and enhance corrosion resistance prior to coating.
9. Zinc-Rich Epoxy Primer
A zinc-rich epoxy primer is applied to provide sacrificial corrosion protection beneath the top coat, helping protect the steel even if the outer coating is damaged.
10. Durable Powder Coat Finish
The upper control arms are finished with Tiger Drylac Bengal Red powder coating and oven cured at 400°F to achieve a fully cured, durable, and long-lasting finish.
Why JBA Powder Coating Lasts Longer
Most upper control arms on the market are simply bead blasted and powder coated in a single step. JBA’s multi-stage preparation, sealing, and priming process significantly improves coating adhesion and corrosion resistance.
This results in a finish that is more resistant to rust, chipping, and environmental wear over time.
Final Quality Inspection
Every JBA upper control arm undergoes a final visual inspection to ensure coating consistency, proper coverage, and finish quality before leaving the facility.
