Description

2-Propenoic Acid, Ammonium Salt, Homopolymer is a water-soluble, synthetic polymer derived from acrylic acid. This versatile polyelectrolyte is valued for its excellent flocculation, dispersion, and water-retention properties. It is a critical component for industries requiring efficient water treatment, mineral processing, and the formulation of specialty coatings and adhesives.

Application

• Water Treatment: Acts as a highly effective flocculant and coagulant aid for clarifying process water, wastewater, and municipal water.
• Mineral Processing: Used as a dispersant and settling agent in the beneficiation of ores such as phosphate, potash, and kaolin clay.
• Paper Manufacturing: Serves as a retention aid, drainage aid, and dry-strength additive to improve paper quality and production efficiency.
• Coatings & Paints: Functions as a thickener, rheology modifier, and stabilizer in water-based formulations.
• Textile Industry: Employed in fabric finishing and as a dye dispersant to enhance color uniformity and fastness.
• Adhesives & Sealants: Provides viscosity control and improves the bonding characteristics of aqueous adhesive systems.
• Agriculture: Used in pesticide formulations and as a soil conditioner to improve water retention.
• Personal Care: Can be found as a thickener and stabilizer in select cosmetic and personal care products.
