POSYNTAN NF100 is an auxiliary agent for dyeing, having high efficacy for all kind of leathers. Its use allows to reduce the affinity of anionic dyes to the chrome-leathers, resulting in a faster penetration and a better colour evenness.
The recommended amount of use is 1-3% on shaved weight.
POSYNTAN NF100 can be added together with the anionic dyes.
On vegetable tanned leathers, where the natural affinity is much lower than with chromeleathers, only small amounts of POSYNTAN NF100 are needed to improve the penetration and the evenness.
POSYNTAN NF100 can also be used for water-proofing and water-repelling leathers, because it doesn’t modify the hydrophobicity.
