Description

Itaconic Acid is a white, crystalline organic acid with significant industrial importance as a bio-based platform chemical. Its unique structure, featuring two carboxylic acid groups and a reactive methylene group, makes it a versatile monomer for synthesizing polymers, resins, and specialty chemicals. This product is essential for manufacturers in the polymer, adhesive, and coating industries seeking sustainable alternatives to petrochemical-derived intermediates.

Application

• Polymer Synthesis: Key monomer for producing polyitaconic acid, styrene-butadiene-itaconic acid (SBI) latex, and other copolymers for superabsorbent polymers, detergents, and dispersants.
• Resins & Coatings: Used in the manufacture of unsaturated polyester resins, alkyd resins, and powder coatings, enhancing flexibility and adhesion.
• Adhesives & Sealants: Serves as a co-monomer to improve the performance and water resistance of acrylic and pressure-sensitive adhesives.
• Chemical Intermediates: A precursor for synthesizing various derivatives, including esters, amides, and pyrrolidones, used in lubricants, plasticizers, and solvents.
• Chelating Agents: Forms effective biodegradable chelating agents for water treatment and cleaning formulations.
• Personal Care: Incorporated into hair styling resins and other cosmetic formulations for its film-forming properties.
