Shenesin JFS
【Chemical Nature】
Condensation product of phenol and organic nitrogen bases
【Properties】
Shenesin JFS disperses the other substances which are applied to the leather during retanning. This generally improves their ability to penetrate, with the result that leathers can be dyed to more level shades, without the shade being made lighter.
Shenesin JFS assists in neutralizing chrome-tanned leathers. Leather treated with Shenesin JFS responds well to buffing, and it can be dyed to intense shades. It is therefore particularly recommended for retanning suede and nubuck.
Shenesin JFS has high light fastness and heat resistance. Its low residual monomer content complies with the latest ecological standards.
