Description

Sulfite Liquors And Cooking Liquors, Spent, Polymer With Formaldehyde is a chemically modified polymer derived from spent sulfite pulping liquors. This product matters as a versatile, cost-effective, and sustainable material, offering unique binding and dispersing properties derived from lignin-based components. It is primarily needed by industries involved in adhesives, construction materials, and agricultural formulations, where it functions as a binder, tackifier, or dispersant. Its production from a by-product stream also aligns with circular economy principles.

Application

• Adhesive Formulations: Used as a tackifier and binder in wood adhesives, particleboard, and laminates.
• Construction Materials: Acts as a binding agent in cement additives, concrete admixtures, and dust control products.
• Agricultural Chemicals: Serves as a dispersant and binder in pesticide formulations, seed coatings, and fertilizer granules.
• Foundry Sand Binders: Employed in core and mold binders for metal casting processes.
• Oilfield Chemicals: Utilized as a component in drilling mud additives and fluid loss control agents.
• Textile Auxiliaries: Functions as a sizing agent or finishing chemical in textile processing.
• Pelletizing Aid: Used as a binder in the agglomeration of fine powders, such as mineral ores or biomass.
