Lignin as a Binder

Lignosulfonates are a very effective and economical adhesive, acting as a binding agent or “glue” in pellets or compressed materials. Lignosulfonates used on unpaved roads reduce environmental concerns from airborne dust particles and stabilize the road surface. This binding ability makes it a useful component of:

Binder for Fertilizer

  • Biodegradable Plastic
  • Coal briquettes
  • Plywood & particle board
  • Ceramics
  • Animal feed pellets
  • Carbon black
  • Fiberglass insulation
  • Fertilizers and herbicides linoleum paste
  • Dust suppressants
  • Soil stabilizers

Lignin as a Dispersant

Lignosulfonate prevents the clumping and settling of undissolved particles in suspensions. By attaching to the particle surface, it keeps the particle from being attracted to other particles and reduces the amount of water needed to use the product effectively. The dispersing property makes lignosulfonate useful in:

  • Cement mixes
  • Leather tanning
  • Clay and ceramics
  • Concrete admixtures
  • Dyes and pigments
  • Gypsum board
  • Oil drilling muds
  • Pesticides and insecticides

Lignin as an Emulsifier

Lignosulfonate stabilizes emulsions of immiscible liquids, such as oil and water, making them highly resistant to breaking. Lignosulfonates are at work as emulsifiers in:

  • Asphalt emulsions
  • Pesticides
  • Pigments and dyes
  • Wax emulsions

Lignin as a Sequestrant

Lignosulfonates can tie up metal ions, preventing them from reacting with other compounds and becoming insoluble. Metal ions sequestered with lignosulfonates stay dissolved in solution, keeping them available to plants and preventing scaly deposits in water systems. As a result, they are used in:

  • Micro-nutrient systems
  • Cleaning compounds
  • Water treatments for boilers and cooling systems
