Zinc Ethyl Silicate paints are inorganic coatings that have good heat & corrosion resistance. The zinc dust in these coatings will protect the metal substrates by cathodic protection (sacrificial anode). Zinc Ethyl silicate paints adhere to the surface strongly and make a barrier layer that no corrosive substances will penetrate anymore.


The International Paint Specification No.20 (SSPC Paint 20) has explained the properties of zinc-rich coatings. Here are some characteristics of zinc ethyl silicate coatings:

  • Good chemical resistance
  • Good anti-corrosion resistance in industrial and marine exposure
  • Excellent weathering resistance
  • Good abrasion resistance
  • Heat resistance up to 400°C (depending on the coating system and condition of application)




IriSil a two-component moisture curing inorganic zinc ethyl silicate coating. It provides excellent corrosion protection. It is specially designed as a primer for coating systems where extended durability is required.


Examples of typical use:

  • Structural steel & piping
  • Offshore environments
  • Refineries & Power plants
  • Bridges, Buildings & Mining equipment


These paints are suitable for long term protection and heavy-duty rust preventing primer. For more information contact us.
