Description

1,3-Isobenzofurandione, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol And 1,2-Propanediol, Dodecanoate is a specialized polymeric resin derived from phthalic anhydride, pentaerythritol, and propylene glycol, terminated with lauric acid. This compound is valued for its role as a versatile building block and modifier in high-performance polymer formulations, offering enhanced flexibility, adhesion, and compatibility. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and specialty plastics industries seeking to fine-tune material properties.

Application

• Alkyd Resin Modifier: Used to improve flexibility, drying time, and gloss in industrial and decorative coatings.
• Adhesive & Sealant Formulations: Acts as a tackifier and compatibility enhancer in pressure-sensitive and structural adhesives.
• Plasticizer & Stabilizer: Incorporated into PVC and other polymer systems to enhance processability and long-term stability.
• Printing Ink Resins: A key component in resin binders for high-quality lithographic and flexographic inks.
• Cross-linking Agent: Utilized in thermosetting polyester and polyurethane systems to control cure profiles and network density.
• Specialty Polymer Synthesis: Serves as a reactive intermediate for creating custom copolymers with tailored properties.
