Description

Unsatd.(C=18) Fatty Acids Dimers, Hydrogenated Polymers With Adipic Acid And 1,4-Butanediol is a high-performance polymeric ester derived from dimerized fatty acids. This specialized chemical is engineered to deliver exceptional flexibility, hydrolytic stability, and adhesion properties in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Dispersions (PUDs): Serves as a key polyol component for producing flexible, waterborne polyurethane coatings and adhesives with excellent mechanical properties.
• Hot-Melt Adhesives: Imparts superior flexibility, low-temperature performance, and adhesion to diverse substrates, including plastics and metals.
• Solvent-borne Coatings & Inks: Used as a polymeric plasticizer and resin modifier to improve film flexibility, gloss, and weatherability.
• Elastomers and Sealants: Acts as a backbone polymer for creating flexible, durable, and hydrolysis-resistant elastomeric products.
• Powder Coating Flexibilizers: Incorporated to reduce brittleness and improve the impact resistance of thermosetting powder coatings.
• Specialty Plasticizers: Provides permanent, non-migrating plasticization for PVC and other polymer systems where high performance is required.
