Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Castor Oil, Phthalic Anhydride And Polyethylene Glycol is a specialized polymeric resin derived from the condensation of unsaturated C18 fatty acid dimers, castor oil, phthalic anhydride, and polyethylene glycol. This engineered chemical offers a unique combination of flexibility, adhesion, and compatibility, making it a valuable intermediate for high-performance formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and functional properties.

Application

• Coatings & Inks: Acts as a polymeric modifier and resin in alkyd coatings, polyurethane dispersions (PUDs), and flexographic inks to improve flexibility, gloss, and adhesion to various substrates.
• Adhesives & Sealants: Serves as a tackifying resin and plasticizer in hot-melt, pressure-sensitive, and structural adhesives, as well as in sealants for enhanced bond strength and elasticity.
• Polymer Modification: Used as a compatibilizer and impact modifier in engineering plastics and rubber compounds to tailor mechanical properties and processing characteristics.
• Lubricant & Grease Additives: Functions as a thickener and performance additive in synthetic lubricants and greases, providing improved viscosity index and extreme pressure properties.
• Textile & Leather Auxiliaries: Employed as a softening agent and finishing resin to impart suppleness, water repellency, and durability to treated fabrics and leathers.
• Foundry & Mold Release: Utilized in core binders and as a component in mold release agents for the metal casting industry.
