>>> If we need to add some color back, I guess we would Aniline-21?
Aniline-21 is the base structural dyestuff originally used for aniline, semi-aniline, suede and nubuck - it is a staining dyestuff that works by “hydrogen bonding” (a “positive” ionic leather protein fiber that link with the “negative” ionic dyestuff) on contamination free structure and surface. When the leather structure is contaminated with body oil, grease and sweat, as an example the result may be blotchy. Surfactant-3.6 is first applied to observe any surface tension that may result in blotchiness prior to Aniline-21 application, to save the tedious task of removing otherwise any dyestuff unevenness.
That is why Aniline-76 is developed for aniline surface coating.
And Nubuck-17, Nubuck-28 and Nubuck 29 developed for Nubuck.
Note this chair is a combination of Aniline and Nubuck finishes and should be kept distinctly separated to retain its original characteristic appearances.
