DYESTUFF DISPERSANTS
BORREGAARD LIGNOTECH‘S DYE DISPERSANTS

Borregaard LignoTech offers a range of primary and secondary dispersants for use in disperse,
vat, reactive and acid dyes. Our high quality dispersants are based on a renewable, naturally
occurring raw material source and offer the following benefits:
• Milling economy
• Wide range of heat stability
• Controlled fibre staining
• Azo reduction
• Lower paste viscosity in the formulation
• Improved cost/performance after standardization of dye strength
• Environmentally friendly
MILLING ECONOMY AZO REDUCTION

Grinding efficiency is the ability to reduce the milling time Color loss in azo dye systems is the result of nitrogen bond
required to achieve a desired particle size during milling. breakage in the dye structure.
Grinding particles to colloidal size increases the surface
energy considerably. When a dispersant is adsorbed onto Our secondary dispersants contribute to lower azo
the dye particle, the surface energy is decreased, thus bond reduction and improved coloration due to lower
stabilizing the system. Fast adsorption of the dispersant interference with the dye structure.

grinding efficiency and stability of the dispersion. RECOMMENDED USE
