Description

2-Propenamide, 2-Methyl-, Polymer With 1-Ethenyl-2-Pyrrolidinone is a synthetic copolymer of N-vinylpyrrolidone (NVP) and methacrylamide. This versatile polymer is engineered to provide excellent film-forming, binding, and thickening properties in aqueous systems. It is a critical raw material for formulators in the personal care, pharmaceutical, and industrial coating sectors seeking reliable performance and consistent quality.

Application

• Hair Care Products: Used as a film-forming agent and styling polymer in hair sprays, gels, and mousses to provide hold, shine, and humidity resistance.
• Skin Care & Cosmetics: Acts as a stabilizer, thickener, and binder in creams, lotions, sunscreens, and makeup formulations, enhancing texture and product stability.
• Pharmaceutical Coatings: Serves as a film-coating agent for tablets and granules, providing a protective barrier, controlled release, or taste-masking properties.
• Adhesives & Sealants: Functions as a rheology modifier and binder in water-based adhesive systems, improving application properties and bond strength.
• Industrial Coatings: Employed as a dispersant and viscosity modifier in pigment concentrates and water-based paints to ensure uniform application and stability.
• Printing Inks: Enhances the viscosity and binding characteristics of aqueous ink formulations for improved print quality and substrate adhesion.
