Description

Hydroxyethyl Methacrylate-Methacrylic Acid-Ethyl Methacrylate Copolymer is a synthetic, film-forming polymer designed to deliver specific rheological and adhesion properties. This versatile copolymer is engineered to provide excellent binding strength, water resistance, and compatibility with a wide range of polar and non-polar systems. It is a critical raw material for formulators in the personal care, pharmaceutical, coatings, and adhesive industries seeking to enhance product performance and stability.

Application

• Hair Styling & Fixative Products: Serves as a primary film-forming agent in hair sprays, gels, and mousses, providing strong hold, humidity resistance, and excellent gloss.
• Skin Care & Color Cosmetics: Used in sunscreens, foundations, and mascaras to improve water resistance, enhance pigment dispersion, and create durable, flexible films on the skin.
• Pharmaceutical Coatings: Employed in enteric or controlled-release tablet coatings, where its pH-dependent solubility profile is utilized for targeted drug delivery.
• Industrial & Specialty Coatings: Functions as a binder in water-based or solvent-based coatings, offering good adhesion to various substrates and improving overall film integrity.
• Pressure-Sensitive Adhesives (PSAs): Modifies tack, peel, and shear properties in adhesive formulations for labels and tapes.
• Textile & Leather Finishes: Imparts durable, flexible, and water-repellent finishes to fabrics and leather goods.
