Aluminium Pigmented Bituminous Ship-bottom Anti-corrosive Paint L44-81 is a primer. It is suitable for ship-bottom areas as an anti-corrosive primer for ship bottoms, and can also be used for corrosion protection of immersed facilities such as condensate pipes, wharf pontoons and interiors of water tanks. It is composed of coal tar pitch, anti-corrosive pigments such as aluminium powder, extender pigments, coal tar solvents, etc. The paint film contains a relatively high amount of aluminium powder and has a certain resistance to atmospheric exposure. Parameters on this page: volume solids 53 ± 3%, dry film thickness 40 µm, theoretical spreading rate 99 g/m².

This product is mainly composed of coal tar pitch and leafing aluminium powder, etc. After a period of storage, because
the black pitch has a strong colouring effect, and the aluminium powder is affected so that its colour changes from silver to silver-brown,
causing the paint film colour to darken. This is a normal phenomenon and has no effect on anti-corrosive performance.
