HR 60 Extra G (Black)
Two-Pack Cold Cured Epoxy-based Hydrophobic Lining for Acidic to Strongly Alkaline Media - Electrically Conductive
SÄKAPHEN HR 60 Extra G (Black) is a high-quality two-pack epoxy hydrophobic electrically conductive lining and coating, formulated for self-priming and direct to metal application. HR 60 Extra G (Black) is chemically resistant to various acidic and strongly alkaline substances ranging from fuels and hydrocarbons to all types of water including brackish, river and sea water and deionized water. The product is resistant to temperature fluctuations.
The lining film surface is hard elastic with excellent hydrophobic properties, preventing caking, fouling and incrustation, following polymerization the lining is fully machinable. HR 60 Extra G (Black) is a low-solvent containing ultra-high volume of solid (wt. %) of 80% or more. The lining is resistant to temperature fluctuations.
For the lining of substrates requiring a smooth, low friction surface offering anti-static properties in potentially flammable areas due to an electrical volume resistance below 107Ω. These can be found in Tanks, Silos, Funnels and Trays where flammable products are being stored or discharged. Can be applied on site and on concrete.
