Our complete range of dyeing auxiliaries for wet end processing.
Achieving the desired color tone while making sure it is uniform across the entire surface is crucial for every tanner. Bomapell’s dyeing auxiliaries are suitable for all skin types and guarantee optimal results.
Whether it’s dye penetration into the leather, dye uniformity, shade brightness, color intensity, or dye fixation, Bomapell auxiliaries help tanners meet any need.
BOMASINT NSC
Dispersant/Dinaphthalene methane sulfonate sodium
Main features
BOMASINT NSC is a synthetic auxiliary tannin. Due to its anionic nature, it promotes dyeing uniformity by reducing the affinity of anionic dyes (acid and substantive dyes), particularly when dyeing chrome-tanned leather, thereby slowing down the rate at which the dye sets to ensure better uniformity and depth of colour.
BOMASINT NSC is a powder that dissolves easily in cold water.
BOMASINT NSC can also be added undissolved to the dye bath.
BOMAFIX RZ
Polyamine Condensation Product – Tincture Fixative
Main features
BOMAFIX RZ is a special cationic polymer used during the dyeing process with acid or direct dyes.
Its use is particularly recommended where the aim is to improve dye yield and enhance the brilliance of the colour in the dyeing process.
BOMAFIX RZ significantly increases both the exhaustion of the
dye baths and the fixation of the dye on the leather.
Consequently, the use of BOMAFIX RZ in a fresh bath at the end of the dyeing process
significantly improves the fastness of the dye to chemical and physical stresses such as: rubbing, acidic and alkaline perspiration, etc.
