Description

2-Butenedioic Acid (2E)-, Di-C8-18-Alkyl Esters, Polymers With Vinyl Acetate is a high-performance polymeric ester derived from maleic acid and vinyl acetate, designed for advanced material science applications. This specialized copolymer offers unique properties as a film-forming agent, internal plasticizer, and rheology modifier, providing enhanced durability and flexibility to polymer matrices. It is a critical raw material for formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for specialty polymer production.

Application

• Coatings & Paints: Acts as a film-forming agent and internal plasticizer in industrial and architectural coatings, improving flexibility, adhesion, and water resistance.
• Adhesives & Sealants: Used as a tackifier and modifier to enhance cohesive strength, adhesion to low-energy surfaces, and elongation properties.
• Polymer Modification: Serves as a reactive comonomer or additive to modify the rheology, impact resistance, and processing characteristics of base polymers like PVC, acrylics, and polyolefins.
• Inks & Pigment Dispersions: Functions as a grinding aid and dispersant for organic pigments, improving color strength, stability, and flow in printing ink systems.
• Textile & Leather Finishing: Imparts softness, water repellency, and durable press properties to fibers, fabrics, and leather goods.
• Lubricant & Grease Additives: Employed as a viscosity modifier and extreme pressure (EP) additive in synthetic lubricants and industrial greases.
