Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Methyl-2-Propenoic Acid, Ammonium Salt is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized ammonium salt of a multi-monomer polymer offers excellent film-forming, binding, and dispersing properties. It is a critical raw material for formulators in the coatings, adhesives, and construction chemical industries seeking to enhance product performance and stability.

Application

• Water-Based Paints & Coatings: Acts as a highly effective binder and film-forming agent, contributing to scrub resistance, adhesion, and durability in interior and exterior emulsion paints.
• Construction Chemicals: Used as a key component in cementitious tile adhesives, grouts, self-leveling compounds, and exterior insulation finishing systems (EIFS) to improve workability, water retention, and flexural strength.
• Adhesives & Sealants: Serves as a primary polymer in the formulation of pressure-sensitive adhesives (PSAs) and water-borne sealants, providing strong tack and cohesive strength.
• Textile & Non-Woven Binders: Functions as a durable binder for fiber bonding in non-woven fabrics and as a finishing agent for textiles to improve hand feel and dimensional stability.
• Paper Coating: Enhances the binding of pigments and fillers in paper coating formulations, improving printability, gloss, and surface strength.
• Industrial Dispersants: Utilized as a grinding aid and stabilizer for inorganic pigments and fillers in aqueous suspensions, preventing re-agglomeration and settling.
