Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Propenoic Acid, Ammonium Salt is a specialized ammonium salt of a synthetic copolymer, designed to deliver enhanced performance in aqueous systems. This product matters for its ability to act as a highly effective dispersant, rheology modifier, and stabilizer, offering superior compatibility and functionality. It is primarily needed by formulators in the coatings, adhesives, construction chemicals, and textile processing industries seeking to improve product stability and application properties.

Application

• Coatings & Paints: Acts as a pigment dispersant and grinding aid in water-based architectural and industrial coatings to prevent settling and improve color development.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in cementitious systems like self-leveling compounds and tile adhesives to enhance workability and strength.
• Adhesives & Sealants: Functions as a rheology modifier and stabilizer in aqueous adhesive formulations, improving open time and application consistency.
• Textile Processing: Serves as a dye dispersant and leveling agent, ensuring uniform dye uptake and improved fastness properties on synthetic fibers.
• Paper Coatings: Utilized as a retention aid and dispersant for pigments like calcium carbonate and kaolin, improving coating quality and printability.
• Ceramic & Clay Processing: Enhances the deflocculation and rheology of ceramic slurries and clay bodies for more efficient casting and shaping.

Quality Control

Our production of this copolymer ammonium salt adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. While typically supplied as a technical grade material, specifications for key parameters such as solid content, pH, viscosity, and ionic character are tightly controlled. Certificates of Analysis (COA) documenting these parameters are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
