Description

Butyl Methacrylate/Dim Ethylaminoethyl Methacrylate Copolymer is a synthetic copolymer designed to impart specific functional properties to advanced material formulations. This product matters for its unique combination of hydrophobic butyl groups and cationic aminoethyl functionality, enabling versatile performance in demanding applications. Industries requiring advanced rheology modifiers, film formers, or charge-modifying agents, such as the personal care, coatings, and specialty adhesives sectors, will find this copolymer essential for developing high-performance products.

Application

• Hair Care Styling Products: As a key film-forming agent and fixative resin in hair sprays, mousses, and gels to provide strong hold and humidity resistance.
• Conditioning Formulations: Acts as a cationic conditioning polymer in shampoos and conditioners, improving wet combing, manageability, and imparting a soft feel.
• Industrial & Protective Coatings: Used as a binder or rheology modifier to enhance adhesion, film integrity, and chemical resistance in various coating systems.
• Pressure-Sensitive Adhesives (PSAs): Modifies tack, peel strength, and shear resistance in adhesive tapes and labels.
• Printing Inks: Serves as a grinding resin and dispersant for pigments, improving ink stability, gloss, and adhesion to substrates.
• Textile & Leather Finishing: Provides durable hand feel, water repellency, and anti-static properties to treated fabrics and leathers.
• Pharmaceutical & Cosmetic Delivery Systems: Utilized in the formulation of controlled-release matrices or as a stabilizer for emulsions and suspensions.
