Description

Sodium Styrene/Acrylates Copolymer is a synthetic, anionic polymer widely used as a film-forming agent and stabilizer. This versatile compound is valued for its ability to enhance texture, stability, and performance in aqueous formulations. It is a critical ingredient for manufacturers in the personal care, coatings, and adhesive industries seeking reliable rheology modifiers and binders.

Application

• Personal Care & Cosmetics: Primary film-former and stabilizer in hair styling gels, mousses, and sprays; used in sunscreens, creams, and lotions for water resistance and improved skin feel.
• Coatings & Paints: Acts as a binder and rheology modifier in water-based architectural paints, industrial coatings, and primers to improve film integrity and application properties.
• Adhesives & Sealants: Functions as a key component in pressure-sensitive adhesives (PSAs) and aqueous adhesive formulations, providing tack and cohesive strength.
• Textile & Leather Processing: Utilized as a finishing agent and binder in textile coatings and leather treatments to impart stiffness, gloss, or water repellency.
• Paper & Packaging: Employed as a coating binder to improve printability, gloss, and barrier properties of paper and paperboard.
