Si 17 N

Phenolic Based Heat Cured Lining for Highly Acidic to Weak Alkali Media and Metal Oxychlorides. Satin Grey Olive Finish

SÄKAPHEN Si 17 N is a high-quality 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 smooth 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.

Filler fuses with a crystalline structure, similar to diamonds, to create a unique mechanical stability due to their covalent bonding, thus increasing the mechanical and chemical resistance of the lining.
