Description

Lignosulfonic Acid, Sodium Salt, Polymer With Formaldehyde, Hydroxybenzenesulfonic Acid And 4,4-Sulfonylbisphenol, Sodium Salt is a high-performance, water-soluble synthetic polymer derived from renewable lignin sources. This engineered material is valued for its exceptional dispersing, binding, and complexing properties in demanding industrial formulations. It is a critical component for manufacturers in sectors requiring robust, multifunctional additives, such as construction, agriculture, and specialty chemical production.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer, improving workability and final strength of cementitious systems.
• Agricultural Formulations: Used as a dispersant and stabilizer in pesticide and herbicide suspensions and wettable powders.
• Oilfield Drilling Fluids: Serves as a deflocculant and fluid loss control additive in water-based mud systems.
• Dye & Pigment Dispersions: Enhances the stability and color strength of aqueous pigment pastes and dye solutions.
• Ceramic & Refractory Processing: Functions as a binder and rheology modifier in slurry formulations for casting and shaping.
• Industrial Cleaners: Utilized as a sequestrant and dispersant for scale inhibition in boiler and cooling water treatments.
• Textile Auxiliaries: Employed in dyeing processes to improve levelness and reduce agglomeration of colorants.
• Foundry Sand Binders: Acts as a core binder in sand casting processes for metal parts manufacturing.
