Description

2-Butenedioic Acid (Z)-, Dibutyl Ester, Polymer With Ethenyl Acetate And Sodium Ethenesulfonate is a specialized polymeric dispersant and rheology modifier designed for high-performance industrial applications. This copolymer is engineered to provide superior particle stabilization and viscosity control in complex aqueous and solvent-based systems. It is a critical raw material for formulators in the coatings, adhesives, and construction chemical industries seeking to enhance product performance and process stability.

Application

• As a high-efficiency dispersant for inorganic pigments (e.g., titanium dioxide, iron oxides) and fillers in water-based architectural and industrial coatings.
• As a rheology modifier and stabilizer in synthetic polymer dispersions (e.g., acrylic, styrene-acrylic) to prevent settling and improve application properties.
• In the formulation of construction chemicals, including tile adhesives, grouts, and self-leveling compounds, to improve workability and water retention.
• As a processing aid and anti-settling agent in agrochemical suspensions (SC formulations) and ceramic slurries.
• For the stabilization of mineral suspensions in drilling fluids and other oilfield chemical applications.
• In textile printing pastes and dye dispersions to ensure color uniformity and prevent agglomeration.

Quality Control

Our production of this polymeric dispersant adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solid content, viscosity, pH, and ionic character are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific lot specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); ensure containers are securely sealed after use to prevent moisture absorption, which may affect product performance.
