Description

2-Methyl-2-Propenoic Acid Polymer With Ethyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate, Sodium Salt is a synthetic, water-soluble polymer belonging to the class of acrylic-based polyelectrolytes. This terpolymer is valued for its excellent thickening, stabilizing, and film-forming properties in aqueous systems. It is a critical raw material for formulators in industries such as paints & coatings, adhesives, textiles, and personal care, where consistent rheology modification and performance are required.

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 sizing agent, thickener for printing pastes, and finishing agent to improve fabric hand and durability.
• Personal Care Products: Functions as a film former, stabilizer, and viscosity-increasing agent in hair gels, creams, and lotions.
• Construction Chemicals: Employed as a water-retention agent and workability aid in cement-based products like tile adhesives and grouts.
• Paper Coating: Used to improve the binding strength, smoothness, and printability of paper coatings.
• Detergents & Cleaners: Can act as an anti-redeposition agent and soil suspension aid in liquid detergent formulations.

Quality Control

Our production of this acrylic terpolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solids content, viscosity, pH, and residual monomers are rigorously tested. Certificates of Analysis (COA) documenting all relevant specifications are available upon request 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); the container must be kept tightly sealed after initial use to prevent moisture absorption and caking.
