Description

1,2-Propanediol Dibenzoate is a high-purity benzoate ester derivative of propylene glycol. This compound serves as a versatile and effective plasticizer and solvent intermediate, valued for its compatibility with a wide range of polymers and resins. It is primarily utilized in the production of adhesives, coatings, and specialty plastic formulations where controlled solvency and low volatility are required.

Application

• Primary Plasticizer for polyvinyl chloride (PVC), cellulose acetate, and other synthetic resins.
• Solvent and Coalescing Agent in industrial and architectural coating formulations.
• Adhesive Formulation Component, enhancing flexibility and adhesion in pressure-sensitive and hot-melt adhesives.
• Additive for Printing Inks, improving pigment wetting and film formation.
• Intermediate for Chemical Synthesis in the production of specialty esters and polymers.
• Component in Sealant and Caulk Formulations to modify rheology and durability.
