Si 14 E BKW
Phenolic-Based Heat Cured Hydrophobic Lining for use as Top Coat for Si 14 E for Highly Acidic to Weak Alkali Media, especially Chlorinated Hydrocarbons. High Gloss, Clear Finish
SÄKAPHEN Si 14 E BKW is a high-quality hydrophobic single-component phenolic based thermosetting heat cured lining, developed as a top coat for Si 14 E.
Si 14 E BKW is chemically resistant to organic and inorganic acids, salt solutions, aliphatic and aromatic chlorinated hydrocarbons. Si 14 E BKW is also resistant to temperature fluctuations and once polymerized is fully machinable.
The lining film surface is hard elastic with excellent hydrophobic properties, preventing caking, fouling and incrustation.
Free from fillers and pigmentation as a final top coat for SÄKAPHEN Si 14 E, particularly for the internals of ISO Tank Containers, Vessels and Storage Tanks where protection from Chlorinated Hydrocarbons is required.
