PHENOLIC EPOXY-BASED HYDROPHOBIC COATING FOR STRONGLY ALKALINE TO WEAKLY ACIDIC MEDIA. OFFERS EXCELLENT ABRASION RESISTANCE. DARK GREY, SATIN FINISH.

SÄKAPHEN® Si 570 AR is a high-quality hydrophobic phenolic epoxy-based heat-cured thermosetting coating.

The coating is chemically resistant to liquids, fumes and mist (also in droplets) of strongly alkaline to weakly acidic media, all types of cooling water, including brackish, river and sea water as well as deionized water, salt solutions, greases, oils and gases.

SÄKAPHEN® Si 570 AR offers excellent abrasion resistance especially for rotating equipment.

The coating offers twice the heat conductivity of SÄKAPHEN® Si 57® E - confirmed by 3M®.

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

 

Field of application:

  In particular for the coating of impellers and parts that are exposed to aggressive and abrasive alkaline substances at high temperature.
