Key Players
Competitive Landscape
Companies compete on whether their products protect several metals and still fit the approved steps from surface prep to e-coat. PPG shows phosphate surface prep as the first step before electrocoat. Nihon Parkerizing develops phosphate and zirconium treatment routes for vehicle paint bases. Atotech shows phosphate-free multi-metal surface prep through its Interlox platform for industrial coating preparation. A wide product range helps only when plant teams prove stable bath control. They must also show that the later coat works under normal line conditions.
Companies also compete on how much heat and sludge a bath adds to the line. Phosphate-free systems can cut one plant burden. Lower-temperature phosphate routes can keep more of the known process. Plant teams still need support before they change an approved set of steps. They must test the exact metal mix and the needed bath controls. Brownfield lines favor suppliers that bring the treatment product with test data. These plants need a practical retrofit plan instead of a process made only for a new site.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| September 2026: Henkel disclosed APNR 2.0 as a new no-rinse adhesion promoter for aluminum pretreatment. | Need for fewer rinse stages and stable paint adhesion | No-rinse aluminum pretreatment is moving into new product development as finishers target lower resource use without losing coating preparation quality. | Coil and profile lines can evaluate shorter pretreatment sequences when adhesion results remain inside established specifications. |
| June 2026: PPG reported that ENVIRO-PRIME EPIC low-temperature electrocoat received a 2026 Ringier Technology Innovation Award. | Need for lower-temperature downstream coating without sacrificing corrosion protection | Low-temperature electrocoat is receiving independent technical recognition as manufacturers target lower curing energy and process efficiency. | Pretreatment suppliers can align bath changes with downstream low-temperature coating programs when the complete corrosion system remains qualified. |
| May 2026: Chemetall opened its first Vietnam surface-treatment application laboratory with liquid, panel and workpiece testing for technical trials. | Shorter validation cycles for local production | Application laboratories are moving closer to production clusters so chemistry can be tested against customer specifications before plant conversion. | Regional testing can shorten qualification of new pretreatment routes without forcing a full production trial first. |
DuBois Chemicals and Quaker Houghton show current conversion-coating platforms for multi-metal or paint-surface prep needs. Atotech / MKS and SurTec show similar current platforms.

These companies cover full vehicle coating systems and specialist surface-treatment products. Their recorded routes include phosphate and phosphate-free options.
Which companies connect pretreatment directly with electrocoat operations?
PPG and Chemetall / Surventis show surface prep that connects with later coating steps. Nippon Paint Surf Chemicals and Nihon Parkerizing also show routes tied to paint-base prep. SurTec and Atotech / MKS publish surface-prep systems tied to downstream coating or e-coat needs.
Which companies document phosphate-free multi-metal pretreatment?
Chemetall / Surventis and Nihon Parkerizing publish phosphate-free or zirconium routes for several metals. DuBois Chemicals and Quaker Houghton show similar treatment options. Atotech / MKS and SurTec also publish multi-metal routes that use lower-impact chemistry.
What differentiates the strongest technical-service positions?
Application labs and bath-control skills help suppliers move a product from panel tests into line use. Local troubleshooting lowers risk during that change and helps plants stay inside the approved bath range.
Why does legacy zinc phosphate remain commercially relevant?
Zinc phosphate remains important because many plants already have approved rust results and bath ranges. A bath change may save some energy or sludge. Plants may still avoid switching when the new route adds more tests or line risk.

Research Methodology
The companies shown here illustrate current competition in e-coat surface prep. The list does not rank every supplier in the market. FMI includes a company only when current evidence supports its surface-prep products or a recorded surface-treatment route for coating prep. Dated developments rely on official company or certification records and keep the reported event status. Each capability applies to the named surface-prep or surface-treatment platform. It does not apply to the company's wider portfolio without proof. FMI keeps its market-share estimates private for the 2026 to 2036 forecast period and does not reproduce them here.
