Si 17 E

Phenolic Based Heat Cured Hydrophobic Lining for Highly Acidic to Weak Alkali Media. Electrically conductive. Satin Olive Finish

SÄKAPHEN Si 17 E is a high-quality hydrophobic single-component electrically conductive phenolic based thermosetting heat cured lining. The lining is self-priming and developed for direct to metal application. The electrical volume resistance is below 107Ω.

Si 17 E is chemically resistant to various liquid and gaseous media, including but not limited to organic and inorganic acids, aliphatic and aromatic hydrocarbons, salt solutions, oils and greases and acidic to weakly alkaline liquids up to max. pH 8. The lining is also resistant to temperature fluctuations.

Si 17 E also provides high impact and abrasion resistance. The surface contains exceptional hydrophobic properties, preventing caking, fouling and incrustation and is resistant to water vapor diffusion (≤ ΔT 85°C). Si 17 E once polymerized is fully machinable.

For the lining of Containers and Process Vessels for storing and transporting chlorinated hydrocarbons and flammable liquids, classified as dangerous according to class AI / AII and B and water endangering media (aliphatic and aromatic chlorinated hydrocarbons) due to an electrical volume resistance below 107Ω.
