Description

2-Butenedioic Acid (2Z)-, Mono(1-Methylethyl) Ester, Reaction Products With Maleic Anhydride And Polyethylene, Ethoxylated Propoxylated is a specialized polymeric surfactant and dispersant derived from maleic anhydride chemistry. This product is engineered to provide exceptional performance as a wetting agent, emulsifier, and viscosity modifier in complex formulations. It is particularly valuable for industries requiring high-performance surface-active agents with tailored hydrophilic-lipophilic balance (HLB) properties. The CAS number for this compound is 75535-30-7.

Application

• Pigment and Filler Dispersion: Acts as a highly effective grinding aid and dispersant for inorganic pigments (e.g., titanium dioxide, iron oxides) and fillers (e.g., calcium carbonate, talc) in water-based coatings, inks, and masterbatches.
• Agricultural Formulations: Used as an emulsifier and stabilizer in suspension concentrates (SC) and oil-in-water (EW) emulsions for pesticides and herbicides, improving tank-mix stability and spray performance.
• Construction Chemicals: Serves as a plasticizer and workability aid in cementitious systems, gypsum plasters, and tile adhesives, enhancing flow and reducing water demand.
• Industrial Cleaners & Detergents: Functions as a surfactant and coupling agent in alkaline and acidic cleaning formulations, providing wetting and soil suspension properties.
• Textile and Leather Processing: Employed as a leveling agent, dye dispersant, and softener component in various textile and leather auxiliaries.
• Polymerization Aid: Can be utilized as an emulsifier or stabilizer in the emulsion polymerization of styrene-butadiene, acrylic, and vinyl acetate polymers.

Quality Control

Our production of this polymeric surfactant adheres to strict quality management systems (ISO 9001 certified) to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, hydroxyl value, saponification value, and viscosity. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with global regulatory frameworks such as REACH.

Storage

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