Lignosulfonate used in Dust control

Lignosulfonate could work as naturally binder as its original form of lignin to bind the cellulose and fiber,so it can be used binding agent in pellets or compressed materials,also could used as dust control agent,which will be much more environment friendly and lower cost compared with Chloride.

How lignosulfonate control the dust

Lignosulfonate binds the road dust surface particle,when evaporate it will become the high-viscosity, naturally sticky material traps dust particles,then after sun heat will make a water resistant durable dust control surface.

Features & Benefits

Naturally Occurring Product – Lignosulfonate is a naturally occurring polymer derived from lignosulfonate a by-product of the tree pulping industry. While in the tree, lignosulfonate acts like glue holding the cellulose fibers of pulp together – and that’s what it can do for your roads.

·  Binding Agent – Just like in the tree, lig works as a dust palliative by binding the different sizes of road particles together when applied topically or mixed in. The water used to liquify lignosulfonate for application evaporates as it dries, and that’s how it binds the dust to the larger aggregate with its high-viscosity, naturally sticky material.

·  Visible Application – When lignosulfonate is first applied it has a dark brown color that lets the public and your crew know where it has been applied. The color will fade as traffic and rain slowly wear down the application.

·  Sun Cured – Over time, some of the lignosulfonates can become completely insoluble due to solar heating.

·  Environmentally Safe – It is non-corrosive and non-toxic to nearby plants and wildlife when applied correctly.

·  More Effective – lignosulfonate Sulfonate treatments tend to be more effective at suppressing dust and holding the road together than chlorides on gravel roads containing higher levels of fines and sand, especially in dry, arid climates like the Southwestern United States.

·  Blading Not Required – Although road prep (blading and rolling) will increase the quality of the road and its longevity, it can be used for ungraded areas and just applied topically.


Application rates for a topical application are 0.3-0.5 gallons per square yard.
