Zinc-rich epoxy paint is designed as a primer in coating systems where excellent durability is needed.
They provide good corrosion resistance by cathodic protection. Zinc dust will sacrifice itself and protect the steel substrate which becomes the cathode.
Here are some outstanding characteristics of zinc-rich epoxy primers:
- Provides cathodic protection
- Suitable as a first in various paint systems
- High zinc loading and low VOC level
According to SSPC Paint 20, zinc content coating shall be classified according to the level of zinc dust by weight present in the dried film as follows:
Level 1 — equal to or greater than 85%
Level 2 — equal to or greater than 77% and less than 85%
Level 3 — equal to or greater than 65% and less than 77%
Structural steel and piping exposed to a wide range of corrosive atmospheric environments up to very high. These coatings are recommended for:
- Onshore & Offshore structures like splash zones
- Refineries & Power plants
- Bridges and buildings
- Mining equipment and storage tanks

For application of zinc rich epoxy primer, it is impossible for us to prepare the surface by sand-blast. Is there any solution?
Our zinc content epoxy primer tolerates Sa2 and St3 prepared surfaces. Read the TDS of IriZinc655.
Awesome stuff. Cheers!
