Description

Polymer Aus C20/C22-Fettacrylat Und Maleinsureanhydrid is a high-performance copolymer synthesized from C20/C22 fatty alcohol acrylate and maleic anhydride. This specialized polymer is engineered to deliver exceptional performance as a rheology modifier, dispersant, and film-forming agent in demanding formulations. It is a critical raw material for industries requiring advanced surface modification, pigment stabilization, and controlled viscosity, such as high-end coatings, specialty adhesives, and advanced polymer composites.

Application

• As a dispersing agent and grinding aid for inorganic pigments (e.g., TiO2, iron oxides) and organic pigments in industrial and automotive coatings.
• Primary rheology modifier and thickener in solvent-based and high-solids coating systems to prevent sagging and ensure optimal application properties.
• Key component in adhesive and sealant formulations to enhance wetting, adhesion to low-energy surfaces, and mechanical properties.
• Utilized as a compatibilizer and impact modifier in polymer blends and composites to improve interfacial adhesion and dispersion of fillers.
• Employed in the formulation of printing inks to control flow, improve pigment dispersion, and enhance gloss and print quality.
• Acts as a surface treatment agent for fillers and fibers to improve their compatibility and performance within polymer matrices.
