Composition: It consists of coal tar pitch, aluminum powder and other anti-corrosion pigments, constitution pigments, and coal coke solvents.
Main characteristics: It has good wettability, wet adhesion, rust resistance, water resistance and good alkali resistance to steel. The paint film contains more aluminum powder and has certain resistance to atmospheric exposure, but The film is poor in heat resistance.
Uses: Suitable for the bottom of the ship as a bottom anti-rust primer, can also be used as anti-corrosion of immersed water facilities such as condensing pipes, pontoons, sinks and other interior.

Description: This product is mainly composed of coal tar pitch and floating aluminum powder. After being stored for a period of time, it is black.
Asphalt has a great coloring effect, aluminum powder will be affected by the color from silver and silver brown, resulting in paint film
The darkening of color is a normal phenomenon and will not have any effect on rust prevention performance.
