846 Epoxy Tar High-build Anticorrosive Paint is divided into 846-1 Epoxy Tar High-build Anticorrosive Primer and
846–2 and 846-3 Epoxy Tar High-build Anticorrosive Topcoat. 846-1, 846-2 and 846-3 are Component A
(also referred to as base), and 846A is Component B (also referred to as hardener).
Suitable for hull bottoms, ballast water tanks, dock steel piles, offshore oil drilling platforms, hydraulic steel gates,
mine steel supports and the inner and outer walls of pipelines, as a heavy-duty anticorrosive coating.

primer, 842 Epoxy Micaceous Iron Oxide Anticorrosive Paint. Or applied directly to steel with rust removal quality reaching Sa2.5 grade
on plates.
When used as a ship-bottom anticorrosive paint, 616 Chlorinated Rubber Iron Red High-build Anticorrosive Paint shall be applied over 846 as one
coat, followed by 839 Long-life High-build Antifouling Paint.
In applications without marine biofouling, 846 Epoxy Tar High-build Anticorrosive Paint may be used alone.
Mill-scale-free steel: blast clean to Sa2.5, or abrade with a flexible disc to St3
Shop-primed steel: light sweep blasting, or abrading rusted areas with a flexible disc to St3
Areas burned by welding, flame cutting or fairing: remove weld slag and spatter, grind smooth, then abrade with a flexible disc to St3
When the substrate temperature is below 5°C, the reaction between epoxy and hardener stops and application is not recommended; a winter-grade anticorrosive paint may be selected for application.
| Application method | Airless spray: Thinner 103 Thinner; Thinning 0–5% (by paint weight); Nozzle orifice 0.4–0.5 mm; Outlet pressure 20–30 MPa (approx. 200–300 kg/cm²). Air spray: not recommended for large-area application, only for small-area repair or small coated parts; Thinner 103 Thinner; Thinning 0–10% (by paint weight); Nozzle orifice 2.0–3.0 mm; Air pressure 0.2–0.4 MPa (approx. 2–4 kg/cm²) |
