Description

2-Butenedioic Acid (2E)-, Di-C12-18-Alkyl Esters, Polymers With Vinyl Acetate is a high-performance polymeric ester, specifically a copolymer of fumaric acid esters and vinyl acetate. This compound is engineered to deliver exceptional film-forming, binding, and plasticizing properties, making it a versatile additive in industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product flexibility, adhesion, and durability.

Application

• Industrial Coatings & Paints: Acts as a film-forming agent and plasticizer to improve flexibility, adhesion, and water resistance in solvent-based and high-solid coatings.
• Adhesives & Sealants: Used as a tackifier and binder to enhance cohesive strength, initial tack, and long-term stability in pressure-sensitive and structural adhesives.
• Printing Inks: Serves as a resin component to improve gloss, pigment wetting, and substrate adhesion in various ink systems.
• Polymer Modification: Employed as an internal plasticizer or compatibilizer in vinyl and acrylic polymer blends to modify mechanical properties.
• Textile & Leather Finishing: Functions as a finishing agent to provide softness, water repellency, and durable surface coatings.
• Caulks & Mastics: Imparts flexibility and weatherability to non-hardening sealants and mastic compounds.
