Description

Fatty acids, C18-unsatd., dimers, polymers with dipentaerythritol, ethylenediamine, maleic anhydride, pentaerythritol, phthalic anhydride, soybean oil, tall oil and tall-oil fatty acids CAS NO 106233-18-5 is a high-performance, multi-functional polymeric resin derived from renewable vegetable and tall oil sources. This complex co-polymer is engineered to deliver exceptional adhesion, flexibility, and chemical resistance, making it a critical component in advanced industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and ink industries who require durable, high-quality binders with versatile performance characteristics.

Application

• Industrial & Protective Coatings: Serves as a key resin binder in high-performance alkyd paints, marine coatings, and corrosion-resistant primers, offering excellent gloss retention and durability.
• Adhesives & Sealants: Used as a tackifying and strengthening agent in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding compounds.
• Printing Inks: Functions as a versatile resin in flexographic and gravure ink formulations, providing good pigment wetting, rub resistance, and substrate adhesion.
• Polymer Modification: Acts as a reactive modifier or cross-linking agent in epoxy, polyester, and polyamide systems to enhance flexibility and impact resistance.
• Foundry & Core Binders: Employed in sand-casting processes as a component of binder systems for molds and cores.
• Composite Materials: Utilized in the production of fiber-reinforced plastics and laminates to improve matrix properties and interfacial adhesion.
