TWO-COMPONENT, EPOXY-BASED HYDROPHOBIC COATING FOR ACIDIC TO STRONGLY ALKALINE MEDIA. RED, HIGH GLOSS.

SÄKAPHEN® HR 60® Extra G Red is a superior hydrophobic two-component epoxy-based thermosetting coating.

The coating is chemically resistant to all types of water, including brackish, river and sea water as well as deionized water, various substances ranging from acidic to strongly alkaline, inorganic salts and their solutions, fuels and acidic aqueous solutions and concentrated hydrochloric acid.

The surface is hard elastic with hydrophobic properties and prevents caking, fouling and incrustation.

The coating can be applied on-site. Weather-resistant.

The images are for illustration purposes only and may differ from the actual appearance of the products.

 

Fields of application:

For the coating of blowers, fans and compressors, the corresponding houses, tanks and vessels, piping, spools and prover loops, for the application in water treatment and desalination.

HR 60 Extra G Red has been exposed to the athmospheric conditions present near Abqaiq in the Kingdom of Saudi Arabia for 18 months:

  • ØTemperature from 10°C to 44°C with peaks of 55°C
  • 55% average humidity
  • Sandstorms
  • Salty air

Hardness and impact strength of HR 60 Extra G Red were not affected by the exposure. Apart from the superficial matting no further deterioration within the coating can be determined.
