Si 14 EG
Diffusion resistan, Phenolic Based Heat Cured Lining for Weak Acidic to Light Alkali Media. Matt Red Finish
SÄKAPHEN Si 14 EG is a high-quality single-component phenolic based thermosetting heat cured lining that is resistant to water vapor diffusion (ΔT 85°C). Si 14 EG is self-priming and developed for direct to metal application.
Si 14 EG is chemically resistant to weak acidic to light alkaline aqueous liquids and vapors, organic and inorganic acids, fume gases, aromatic and aliphatic solvents and cooling water including brackish, river and sea water. Si 14 EG is also resistant to temperature fluctuations.
The lining film surface is hard elastic and once polymerized is fully machinable.
For the lining of Condensers, Condensate Receivers, Evaporators, Thermal Degassers, Hot Water and Stream Stressed Plant Parts and Uninsulated Tanks. Especially suitable for plant parts that are exposed to hot water and steam in neutral and acidic environments. Si 14 EG is also resistant to water vapor diffusion.

With non-insulated equipment that is coated, a ∆T > 30°C may cause water vapor diffusion. Through a complex mix of fillers, a lining film resistant to water vapour is created even with a dry film thickness below 1000 microns (1mm).
