Product Overview

Sodium Lignosulfonate is a water-soluble lignin derivative obtained from the sulfite pulping process. It is a complex organic polymer with excellent dispersing, binding, emulsifying, and film-forming properties.Often used in large-scale industrial applications, sodium lignosulfonate serves as a dispersant, binder, and stabilizer in a wide range of products including construction chemicals, animal feed, oil drilling additives, dyes, and adhesives.

Key Features

✔ Excellent Dispersant & Stabilizer — Promotes uniform distribution of solids in liquid systems

✔ Strong Binding Ability — Improves cohesion in granules, pellets, and molded products

✔ Good Film-Forming Properties — Enhances surface coverage and durability

✔ Water Soluble & Easy to Use — Rapid dissolution in aqueous systems

✔ Cost-Effective & Eco-Friendly — Derived from renewable biomass

✔ Compatible with Multiple Systems — Works with pigments, fillers, and contrast agents

Major Applications

1) Construction Materials

Used as an additive in:

• Cement grinding aids

• Concrete admixtures

• Mortars and grout

• Plaster & tile adhesive formulations

Benefits include improved workability, strength development, and reduced water demand.

2) Animal Feed & Agriculture

As a binder or pelletizing aid, sodium lignosulfonate:

• Enhances pellet durability

• Improves nutrient retention

• Facilitates feed processing
  It is also used for soil conditioning and as a carrier in fertilizer blends.

3) Oil Drilling & Mining

In drilling fluids and muds, it:

• Acts as a dispersant and deflocculant

• Reduces viscosity at high temperatures

• Improves drilling efficiency and cuttings removal

4) Dyes & Pigments

Used as a:

• Dye dispersant

• Pigment stabilizer

• Emulsion component
  It helps prevent particle agglomeration and enhances color uniformity.
