Description

2-Propenoic Acid, Polymer With 1-Ethenyl-2-Pyrrolidinone is a synthetic copolymer of acrylic acid and vinylpyrrolidone, known for its excellent film-forming, adhesive, and thickening properties. This versatile polymer is engineered to provide enhanced performance in formulations requiring water solubility, binding strength, and compatibility with a wide range of ingredients. It is a critical raw material for manufacturers in the pharmaceutical, personal care, adhesive, and specialty coatings industries seeking reliable and consistent polymer performance.

Application

• Pharmaceutical Formulations: Used as a binder in tablet manufacturing, a film-forming agent for coatings, and a stabilizer in suspensions and emulsions.
• Personal Care & Cosmetics: Serves as a primary film former and fixative in hair styling products (mousses, gels, sprays) and as a thickener and stabilizer in creams and lotions.
• Adhesives & Sealants: Acts as a key component in water-based pressure-sensitive adhesives (PSAs) and remoistenable adhesives for labels and tapes.
• Specialty Coatings: Employed as a film-forming agent and adhesion promoter in industrial and protective coatings, as well as in ink formulations.
• Textile & Paper Processing: Functions as a sizing agent, coating binder, and processing aid to improve strength and surface properties.
• Detergents & Cleaning Agents: Utilized as a anti-redeposition agent and soil release polymer in laundry and dishwashing formulations.
