Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Sodium Salt is a water-soluble, anionic copolymer of methyl acrylate and butyl acrylate. This specialized polymer is engineered to deliver superior performance as a thickening, suspending, and stabilizing agent in aqueous systems. It is a critical raw material for formulators seeking to enhance the rheology and stability of their products. Key industries that rely on this polymer include paints & coatings, adhesives, construction materials, and personal care.

Application

• Paints & Coatings: Acts as a highly efficient thickener and rheology modifier in water-based latex paints, improving brushability, spatter resistance, and film build.
• Adhesives & Sealants: Provides viscosity control and enhances the stability of water-based adhesive formulations, including pressure-sensitive adhesives (PSAs) and construction adhesives.
• Construction Chemicals: Used as a key additive in cementitious products, tile adhesives, and grouts to improve workability, water retention, and sag resistance.
• Personal Care & Cosmetics: Functions as a thickener and emulsion stabilizer in lotions, creams, and hair care products, providing a desirable sensory feel.
• Textile & Paper Processing: Serves as a sizing agent, coating binder, or processing aid to improve strength, printability, and surface properties.
• Industrial & Institutional Cleaners: Enhances the viscosity and suspension of active ingredients in liquid detergent and cleaner formulations.
