Description

2-Butenedioic Acid (Z)-, Monomethyl Ester, Polymer With Ethenylbenzene, 2,5-Furandione And (Z)-2-Methylpropyl Hydrogen 2-Butenedioate, Ammonium Salt is a specialized ammonium salt of a complex polymeric carboxylic acid, designed to offer unique rheological and dispersing properties. This compound matters for its ability to function as a high-performance dispersant, stabilizer, and rheology modifier in demanding aqueous systems. Industrial users in sectors such as coatings, adhesives, construction chemicals, and advanced material formulations need it to enhance product stability, control viscosity, and improve the dispersion of pigments and fillers.

Application

• Coatings & Paints: Acts as a highly effective dispersant and stabilizer for inorganic pigments (e.g., titanium dioxide, iron oxides) and organic pigments in water-based architectural and industrial coatings.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in cementitious systems, improving workability and final strength of concrete and mortar.
• Adhesives & Sealants: Serves as a rheology modifier and stabilizer in water-based adhesive formulations, ensuring consistent viscosity and preventing filler settlement.
• Ceramics & Inorganic Pigments: Enhances the milling efficiency and stability of slurries, promoting uniform particle size distribution and preventing agglomeration.
• Textile & Leather Auxiliaries: Functions as a dispersing agent for dyes and processing chemicals, improving color uniformity and process efficiency.
• Paper Coatings: Improves the dispersion of clay and calcium carbonate in coating colors, leading to better gloss, smoothness, and printability of paper.
• Industrial & Institutional Cleaners: Can be utilized in formulation to suspend soils and prevent redeposition on surfaces.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
