Surface-Tolerant Epoxy Aluminium Primer (0AR)
This is a two-component, polyamine-cured surface-tolerant epoxy coating. It features high surface tolerance and high solids content. It contains aluminium pigment, which improves protective performance. It is intended for areas where ideal surface preparation cannot be achieved or is not required. In atmospheric and immersion environments it may be used as a primer, intermediate coat, topcoat or one-coat system. It is suitable for suitably prepared carbon steel and aged coated surfaces. It can be applied at surface temperatures below 0°C.
General:
Mainly for maintenance and repair.
Marine coatings:
Hull shell, exterior and interior areas.
Industrial protective coatings:
Recommended for offshore environments such as refineries, power stations, bridges, buildings, mining equipment and general structural steel.
