SÄKAPHEN Si 17 N is a high-quality hydrophobic single-component phenolic based thermosetting heat cured, abrasion and impact resistant lining. Si 17 N is self-priming and developed for direct to metal application.
Si 17 N is chemically resistant to metal oxychlorides (VOCL3), 40% hydrofluoric acid, organic and inorganic acids, fume gases, chlorinated aromatic and aliphatic hydrocarbons, oils and greases. The lining is also resistant to temperature fluctuations.
The surface contains exceptional hydrophobic properties, preventing caking, fouling and incrustation. Si 17 N is resistant to water vapor diffusion (ΔT 85°C) and once polymerized is fully machinable.
For the lining of Storage, Transportation and Process Vessels, Pipework, Rotating Equipment and others where excellent chemical resistance, enhanced abrasion resistance and / or resistance against diffusion is needed.
