Description

2-Butenedioic Acid (E)-, Reaction Products With Abietic Acid, Esters With Glycerol is a specialized resin ester derived from fumaric acid, abietic acid (rosin), and glycerol, commonly known as a fumarated rosin glycerol ester. This product is valued for its excellent film-forming, adhesive, and tackifying properties, making it a crucial component in high-performance industrial formulations. It is primarily sought by manufacturers in the adhesives, coatings, inks, and polymer modification sectors seeking to enhance product durability and performance.

Application

• Hot-Melt Adhesives (HMAs): Acts as a key tackifier and modifier, improving adhesion, flexibility, and thermal stability.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes and labels to provide balanced tack, peel strength, and cohesive strength.
• Industrial & Protective Coatings: Imparts hardness, gloss, and water resistance to solvent-based and oleoresinous coatings.
• Printing Inks: Serves as a resinous binder in gravure and flexographic inks, enhancing pigment wetting and print quality.
• Polymer Modification: Functions as a processing aid and compatibilizer in rubber and plastic compounds.
• Sealants and Caulks: Contributes to elasticity, adhesion, and longevity in construction and automotive sealants.
