Marine Epoxy Primer for Steel Corrosion Protection
Two-component epoxy primer systems for blasted steel, maintenance repair, galvanized surfaces, ship structures, tanks, decks, and offshore steel where strong adhesion and corrosion control are required.
Start from substrate condition and service environment.
JDH06-4 is selected when zinc-rich first-coat protection is specified for marine steel.

|---|---|---|---|---|
| Zinc-rich first coat | JDH06-4 Epoxy Zinc-Rich Anti-Rust PrimerEpoxy zinc-rich anti-rust primer | Use when zinc-rich protection is specified; confirm DFT with latest TDS. | Ship hulls, decks, waterlines, port machinery, heavy steel. | First anti-corrosion layerUse over properly prepared steel |
| General steel primer | JDH815 Iron Oxide Red Epoxy PrimerGeneral-purpose marine steel primer | Selected for marine and industrial steel where epoxy primer adhesion is required. | Steel structures, pipelines, port facilities, hull steel. | Practical baseline primerCompatible with epoxy systems |
| Grey primer / intermediate | JDH816 Grey Epoxy PrimerGrey epoxy primer for marine structures | Use where grey primer color or intermediate role is preferred. | Hulls, decks, cargo holds, ballast tanks. | Marine structure protectionGood system visibility |
| Repair primer | JDH818 Rough Surface Epoxy PrimerPrimer for imperfect or rough steel preparation | For maintenance areas where complete rust removal is difficult. | Repair steel, older hulls, hand-cleaned areas, maintenance work. | Repair-friendlyConfirm preparation grade |
| Zinc phosphate option | JDH819 Epoxy Zinc Phosphate PrimerEpoxy zinc phosphate anti-corrosion primer | Alternative general anti-corrosion primer where zinc phosphate pigment is selected. | Marine steel, industrial steel, coating maintenance. | General corrosion controlSystem compatibility check required |
| Special substrate primer | JDH838 Primer for Galvanized Steel SheetPrimer for galvanized, aluminum, stainless, hard-to-roughen surfaces | Use for non-standard substrates that need special adhesion support. | Galvanized steel, aluminum, stainless steel, workshop repairs. | Special substrate adhesionConfirm topcoat compatibility |
| Final primer choice depends on substrate, surface preparation, service area, topcoat plan, and the latest official TDS. | ||||
Compare Marine Epoxy Primer Options
| Primer Type | Representative Products | Main Use | Substrate Condition | Follow-Up Layer |
|---|---|---|---|---|
| Zinc-rich epoxy primer | JDH06-4 | Heavy-duty first-coat corrosion protection. | Properly prepared carbon steel. | Epoxy intermediate, tie coat, PU or other compatible topcoat. |
| General epoxy primer | JDH815 / JDH816 / JDH819 | Baseline marine steel anti-corrosion primer. | Prepared steel surface according to specification. | Epoxy, polyurethane, chlorinated rubber, or project-specified topcoat. |
| Rough surface epoxy primer | JDH818 | Maintenance and repair when preparation is limited. | Rougher or older steel after suitable cleaning. | MIO tie coat, epoxy intermediate, or topcoat as specified. |
| Special substrate primer | JDH838 | Adhesion primer for galvanized steel, aluminum, and stainless steel. | Hard-to-roughen metal substrates. | Compatible finish coat after confirmation. |
| Tie coat support | JDH263 / JDH817 | Transition between primer and antifouling/topcoat systems. | Sound compatible primer layer. | Antifouling, acrylic PU, or other compatible coating. |
