Suitable for properly prepared carbon steel substrates and recommended to be applied in an automated shop priming line in lower film thicknesses or applied by airless spray when used as holding primer. Compatible with advanced welding technologies including MIG, MAG and G-FCAW when applied in low film thickness.

Suitable as shop primer or holding primer on vessels. Suitable for structural steel and piping to be exposed to corrosive environments up to very high and immersed.
Recommended for offshore environments, refineries, power plants, bridges, buildings, mining equipment and general structural steel.


Prepare carbon steel to Sa 2 1/2. Apply using an airless spray, Conventional sprays and brushes can be used for touch up purposes.
