SÄKAPHEN® SÄKATONIT® Extra AR is a superior hydrophobic mechanically durable two-component epoxy-based 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, acidic aqueous solutions and concentrated hydrochloric acid.

The surface is hard elastic, abrasion and impact-resistant 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 tube sheets, pipe work and prover loops, spill boxes, water boxes, blower-, fan- and compressor-housings, tanks, vessels, inside of filters, valves and agitators. Certain surface imperfections can be covered up by thickness of applied material.
