Description

Lignin, Alkali, Reaction Products With Dimethylamine And Formaldehyde is a chemically modified lignin derivative, specifically a Mannich reaction product. This modification imparts valuable cationic and amphoteric properties to the natural lignin polymer, enhancing its functionality in demanding industrial applications. It is primarily utilized as a high-performance dispersant, flocculant, and retention aid in sectors such as water treatment, paper manufacturing, and construction chemicals.

Application

• Paper Industry: Acts as a cationic retention and drainage aid, improving fiber and filler retention in papermaking processes.
• Water Treatment: Used as an organic flocculant and coagulant aid for the clarification of industrial wastewater and process water.
• Construction Chemicals: Functions as a plasticizer and water-reducing agent in concrete admixtures and cement dispersions.
• Dye & Pigment Dispersion: Serves as a dispersing agent for inorganic pigments and carbon black in various formulations.
• Oilfield Chemicals: Employed as a fluid loss control additive and thinner in drilling mud formulations.
• Agriculture: Can be used as a component in controlled-release fertilizer coatings and soil conditioners.
• Textile Auxiliaries: Utilized in dyeing processes as a leveling agent or dispersant.
