Description

2-Methyl-2-Propenoic Acid Polymer With Butyl 2-Propenoate And Ethenylbenzene, Sodium Salt is a synthetic, water-soluble polymer belonging to the class of acrylic-based copolymers. This versatile material is engineered to provide excellent thickening, stabilizing, and film-forming properties in aqueous systems. It is a critical component for formulators in industries such as paints and coatings, adhesives, textiles, and personal care, where consistent rheology control and product performance are paramount.

Application

• Paints & Coatings: Acts as a rheology modifier and thickener in water-based paints, improving application properties and sag resistance.
• Adhesives & Sealants: Used as a thickening and stabilizing agent in aqueous adhesive formulations to control viscosity and enhance bonding performance.
• Textile Processing: Serves as a binder, thickener for prints, and finishing agent to improve fabric hand and durability.
• Personal Care Products: Functions as a film former, stabilizer, and viscosity-increasing agent in lotions, creams, and hair styling gels.
• Paper Coatings: Employed as a binder and coating additive to improve surface strength, printability, and gloss.
• Construction Chemicals: Used in cement-based mortars, tile adhesives, and grouts as a water-retention agent and workability aid.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solids content, viscosity, pH, and ionic character. A Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption and caking.
