PLURAL COMPONENT, VINYL ESTER NOVOLAC-BASED CONDUCTIVE ABRASION-RESISTANT AND WATER VAPOR-RESISTANT GLASS FLAKE-FILLED COATING FOR STRONGLY ACIDIC TO STRONGLY ALKALINE MEDIA. BLACK, MATT.

SÄKAPHEN® SÄKAFLAKE® 900 Black 3K is a plural component vinyl ester epoxy novolac-based abrasion resitant electrically conductive glass and graphite flake-filled coating, resistant to water vapor diffusion (≤ ΔT 85°C).

The coating is chemically resistant against aggressive substances such as acids, bases, solvents, salt solutions, fluegas and all types of water, including brackish, river and sea water as well as deionized water. The electrical volume is less than 107Ω.

The coating can be applied on-site.


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

 

Fields of application:

 

For the coating of chamber parts of heat exchangers, evaporators and air coolers, blowers, fans and compressor casings, flue gas funnels/channels, flue gas desulfurization equipment, wash towers, process and storage tanks, vessels and containers. For equipment requiring a coating resistant to water vapor diffusion also with high temperature gradients and electrical conductivity.

 

 

Statiically conductive.
