Description

Starch, Oxidized, Polymers With Bu Acrylate, tert-Bu Acrylate And Styrene is a specialized, high-performance graft copolymer designed for advanced material applications. This engineered polymer combines the renewable, film-forming backbone of oxidized starch with the robust mechanical and adhesive properties of synthetic acrylate and styrene monomers. It is essential for formulators seeking to enhance product performance with bio-based content or tailored rheological profiles. Key industries that utilize this material include adhesives, coatings, textiles, and paper manufacturing, where it acts as a binder, thickener, or surface modifier.

Application

• Adhesive Formulations: Serves as a key bio-based component in pressure-sensitive adhesives (PSAs), laminating adhesives, and construction adhesives, offering improved tack and cohesion.
• Coatings and Paints: Functions as a rheology modifier and binder in water-based coatings, providing enhanced viscosity control, film integrity, and substrate adhesion.
• Textile and Nonwoven Finishing: Used as a sizing agent, binder for nonwoven fabrics, or finishing chemical to impart stiffness, strength, or water resistance to fibers.
• Paper and Packaging: Applied as a surface sizing or coating additive to improve printability, strength, and barrier properties of paperboard and packaging materials.
• Construction Materials: Acts as an additive in cementitious mixes, gypsum boards, or ceramic tiles to modify workability, adhesion, and reduce dust.
• Personal Care and Cosmetics: Utilized as a film-forming agent, thickener, or stabilizer in hair styling products, creams, and lotions.
