Description

2-Butenedioic Acid (2E)-, Di-C18-22-Alkyl Esters, Polymers With Vinyl Acetate is a high-performance polymeric ester derived from maleic acid and long-chain fatty alcohols, copolymerized with vinyl acetate. This specialized polymer is engineered to deliver exceptional performance as a rheology modifier, film-former, and dispersing agent in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability, stability, and application properties.

Application

• Industrial Coatings & Paints: Acts as a key rheology modifier and dispersing agent in solvent-based and high-solids coatings, improving pigment suspension, flow, and leveling.
• Adhesives & Sealants: Used as a tackifier and film-forming polymer to enhance adhesion, cohesion, and flexibility in pressure-sensitive and structural adhesive systems.
• Printing Inks: Serves as a viscosity control agent and resin component, contributing to ink transfer properties, gloss, and substrate adhesion.
• Polymer Modification: Employed as an internal plasticizer and processing aid to improve the flexibility and workability of vinyl and other polymer compounds.
• Lubricant & Grease Additives: Functions as a thickener and performance additive to enhance the viscosity index and extreme-pressure properties of lubricating greases.
• Specialty Chemical Intermediates: Utilized in the synthesis of further derivatives for applications requiring specific hydrophobic or film-forming characteristics.
