Description

2-Propenoic Acid, 2-Methyl-, Homopolymer, Potassium Salt is a water-soluble polymer derived from methacrylic acid, known for its excellent thickening, suspending, and stabilizing properties. This high-performance polyelectrolyte is crucial for formulating products that require precise rheology control and enhanced stability in aqueous systems. It is an essential raw material for manufacturers in the personal care, pharmaceutical, and industrial coatings sectors seeking reliable, high-quality additives.

Application

• Personal Care & Cosmetics: Acts as a primary thickener, stabilizer, and suspending agent in shampoos, shower gels, lotions, and creams.
• Pharmaceutical Formulations: Used as a binder, disintegrant, and film-forming agent in tablet coatings and as a viscosity modifier in liquid suspensions and gels.
• Industrial Coatings & Paints: Serves as a rheology modifier and thickener in water-based paints, adhesives, and coatings to prevent sagging and improve application properties.
• Detergents & Cleaners: Enhances the viscosity and stabilizes the suspension of active components and abrasives in liquid soaps and hard surface cleaners.
• Textile & Paper Processing: Utilized as a sizing agent, coating additive, and thickener in processing aids to improve finish and handle.
• Agricultural Formulations: Employed as a stabilizer and suspending agent in pesticide and herbicide suspensions to ensure uniform application.
