Pretreatment
Powerful Pretreatment for Flawless Powder Coat Finish
Surface preparation makes or breaks your coating results. Our custom-engineered metal pretreatment systems get the job done right the first time, whether manual or automatic. Eliminate oils, oxides, and contaminants from metal surfaces quickly with the Autowash multi-stage pretreatment system, or opt for a hands-on approach with the RTS 750 Manual Spray Wand System.
Pretreatment for Paint Adhesion
Whether you apply iron phosphate, zinc phosphate, zirconium, or nano conversion coatings, pretreatment determines your paint adhesion and long-term corrosion resistance. Riveer systems prepare metal parts for powder coating, liquid paint, E-coat, and plating operations, from basic wash booths to fully integrated finishing lines.
Riveer systems capture, contain, and control the entire pretreatment process. Closed-loop recycling options reuse wash solution across every stage for zero-discharge operation. You save on chemistry and water costs while keeping your process environmentally compliant.
Multi-Stage Pretreatment for Powder Coating
Riveer pretreatment systems come in multiple stages, including degrease, rinse, pretreat, and seal, in a range of PLC-controlled configurations. Vacuum recovery isolates each stage to minimize cross-contamination. Cycle times are tuned to your cleanliness spec, so every part gets a consistent, repeatable surface clean at production speed.
Conversion coating application and recovery systems can be fully automated, manual, or hybrid. Riveer engineers work with you to plan for your production volume, part loading, and process chemistry. The result is an easy-to-use, turnkey system built for your operation.
Case Study
AUTOWASH Multi-Stage Pretreatment Eliminates Production Bottlenecks
By replacing manual processes with our multi-stage cleaning system, our customer, Sewer Equipment cuts bottlenecks and rework costs. The company now operates with consistent, rapid cycles. Riveer multi-stage systems recycle every stage of the wash cycle for reuse, delivering higher throughput and lower chemical costs.

Pretreatment FAQs
Are there alternatives to manual wand pretreatment?
Yes. We offer autowash multi-stage pretreatment systems that prep metal parts for powder coating, liquid paint, E-coat, and plating operations. Our fully integrated finishing lines give your operation the flexibility to wash, degrease, and pretreat parts of any size, shape or material before you paint.
What is metal pretreatment for paint and powder coating?
Metal pretreatment cleans and chemically treats metal surfaces before painting, powder coating, E-coat, or plating. The pretreatment process removes oils, oxides, and contaminants, then applies a conversion coating that improves paint adhesion and corrosion resistance.
What is a conversion coating?
A conversion coating is a chemical layer that bonds to the metal surface during pretreatment. Common options include iron phosphate, zinc phosphate, and zirconium. The conversion coating gives the finish coating a stable surface to grip and helps prevent flash rust and long-term corrosion.
How many stages does a pretreatment washer need?
It depends on your cleanliness spec and finish requirements. Riveer configures PLC-controlled systems across full ranges, tailored to your parts.
What causes powder coating adhesion failure?
Most adhesion failures, like peeling and blistering, trace back to inadequate surface preparation. Common causes include oils left on the part’s surface, inconsistent chemistry, and skipped rinse stages. A controlled, repeatable pretreatment process is the most reliable way to prevent rework.
