Description
Propylene Glycol Dibenzoate (CAS 19224-26-1) is a dibenzoate ester plasticizer commercially available under trade names including Benzoflex 284, K-Flex PG, and LexFeel Shine. It carries no assigned E-code and is categorised within the broader family of benzoate ester solvents and plasticizers.
In coatings and adhesive formulations, Propylene Glycol Dibenzoate functions as a primary plasticizer by reducing polymer glass transition temperature, improving film flexibility and substrate adhesion. In printing inks and sealant systems, it acts as a coalescing solvent, lowering the minimum film formation temperature without compromising final film hardness.
Propylene Glycol Dibenzoate is supplied as a liquid-phase ester and falls under REACH registration requirements for EU market supply. Procurement teams should confirm compliance documentation, including Safety Data Sheets and technical data sheets, with the supplying manufacturer. Standard packaging formats vary by supplier volume tier.
