Description

Poly(2-Acrylamido-2-Methyl-1-Propanesulfonic Acid) CAS NO 27119-07-9 is a high-purity, synthetic polyelectrolyte known for its exceptional water solubility and strong anionic charge density. This polymer is valued for its superior performance as a scale inhibitor, dispersant, and viscosity modifier in demanding aqueous systems. It is a critical raw material for manufacturers in the water treatment, oilfield chemicals, personal care, and coatings industries seeking reliable and efficient anionic functionality.

Application

• Water Treatment: Primary application as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Oilfield Chemicals: Key component in drilling fluid formulations to control viscosity, fluid loss, and shale inhibition, and in enhanced oil recovery (EOR) as a thickening agent.
• Personal Care & Cosmetics: Used as a rheology modifier, emulsifier, and antistatic agent in hair care products (shampoos, conditioners) and skin care formulations.
• Coatings & Paints: Acts as a pigment dispersant and stabilizer to prevent settling and flocculation, improving color development and shelf life.
• Textile & Paper Processing: Serves as a dye dispersant, leveling agent, and retention aid to improve process efficiency and product quality.
• Adhesives & Construction: Functions as a thickener and water-retention agent in cementitious mixtures, tile adhesives, and grouts.
