SÄKATONIT Extra AR
Two-Pack Cold Cured Impact Resistant Epoxy-based Hydrophobic Lining / Coating for Acidic to Strongly Alkaline Media. High Gloss, Anthracite Finish
SÄKAPHEN SÄKATONIT Extra AR is a superior two-pack epoxy hydrophobic mechanically durable lining / coating, formulated for self-priming and direct to metal application. SÄKAPHEN SÄKATONIT Extra AR is chemically resistant to various substances ranging from sour to strongly alkaline, inorganic salts and their solutions, fuels, acidic aqueous solutions and concentrated hydrochloric acid (36%) as well as all types of water including brackish, river, sea and deionized.
The lining film surface is hard elastic abrasion and impact resistant with superb hydrophobic properties, preventing caking, fouling and incrustation. Following polymerization SÄKAPHEN SÄKATONIT Extra AR is fully machinable and can be applied on site as well as on concrete. The lining is resistant to temperature fluctuations.
Furthermore, SÄKAPHEN SÄKATONIT Extra AR contains an ultra-high solid volume (wt.%) of 95% or more, in addition to combatting extreme weather conditions, as observed in the desert of Saudi Arabia for an 18 month duration.
For the lining of Tube Sheets, Pipework and Meter Provers (Prover Loops), Spill Boxes, Water Boxes, Blowers, Fans, Compressors, Housings, Tanks, Vessels, Filter Interiors, Valves and Agitators. Slight surface imperfections can be covered by the increased applied thickness.
