Epoxy Bitumen Ultra High-build Anticorrosive 546 is an epoxy coating used as a primer. Suitable as a heavy-duty anti-corrosion coating for ship bottoms, ballast tanks, wharf steel piles, offshore oil drilling platforms, hydraulic steel gates, mine steel supports, and internal and external pipe walls. A two-component high-performance anticorrosive composed of epoxy resin, coal-tar pitch, epoxy curing agent, anti-corrosive pigment, extender pigment, additives and solvent. One airless-spray coat can achieve a dry film thickness of about 250 µm. Parameters on this page: volume solids 69 ± 3% (after mixing), dry film thickness 250 µm, theoretical spreading rate 470 g/m².

702 Epoxy Zinc-Rich Shop Primer, 703 Epoxy Iron Oxide Shop Primer, 704 Inorganic Zinc Silicate Shop Primer
Primer, 842 Epoxy MIO Anticorrosive, or applied directly to steel derusted to Sa2.5
Steel surfaces.
When used as a ship-bottom anticorrosive, apply 616 Chlorinated Rubber Iron-red High-build Anticorrosive over 546 as one
coat as a transition layer, then apply 839 Long-life High-build Antifouling to improve the intercoat
adhesion. In applications free from marine fouling, 546 may be used alone.
Mill-scale-free steel: blast clean to Sa2.5, or abrade with a flexible disc to St3
Shop-primed steel: sweep blast or grind corroded areas to St3 with elastic abrasive discs
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 curing agent stops; outdoor application is not recommended, and the winter-grade epoxy bitumen anticorrosive may be selected
