System Function	Product Recommendation	Typical Role	Suitable Area	Key Benefits
First primer	JDH815 / JDH816	General epoxy primer for prepared hull steel	Below waterline and topside steel	Adhesion and anti-corrosion foundation
Zinc-rich option	JDH06-4	Zinc-rich anti-rust primer where specified	High-protection hull and waterline projects	Strong zinc-layer protection
Tie coat	JDH263	Bridge layer between epoxy primer and antifouling	Underwater hull systems	Improves intercoat adhesion
Antifouling	JD753 / JD744 / JD713	Fouling-control topcoat	Underwater hull and vessel bottom	Self-polishing or chlorinated rubber options
Hull finish	JD918 / JDC43-31	Above-waterline hull finish options	Topsides and visible hull areas	Weathering, color, and maintenance selection

Technical Parameters

Item	Reference Value	Specification Note
Epoxy primer solids	Project-specific by product	JDH815 / JDH816 are common hull primer choices.
Tie coat DFT	Around 50 um typical	Confirm with JDH263 / JDH817 latest TDS.
Antifouling type	JD753 self-polishing or JD744/JD713 chlorinated rubber	Select by voyage profile and dry-dock interval.
Topside finish	PU or alkyd	PU is preferred where gloss and weathering resistance are important.

Construction Suggestions

Before final coating work, verify substrate condition, environment, compatibility, and the latest TDS.

Remove salts, fouling, grease, and loose coating before repaint.
Use tie coat when moving from epoxy primer to antifouling topcoat.
Confirm minimum and maximum recoat intervals before launching.
Record batch number, DFT, temperature, humidity, and dew point for project files.

FAQ

Ask another question ->

Why does a hull system need a tie coat?

A tie coat helps connect epoxy primer or intermediate layers with antifouling paint and reduces intercoat compatibility risk.

Is JD753 suitable for all hulls?

JD753 is a key commercial antifouling option, but the final choice depends on route, vessel speed, idle time, fouling pressure, and dry-docking interval.

Can old antifouling be overcoated?

Only after confirming coating type, adhesion, surface cleaning, and compatibility. Unsound or unknown coatings should be treated cautiously.
