Description

1,3-Isobenzofurandione, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol And Oxybis[Propanol] is a specialized polymeric resin derived from phthalic anhydride, pentaerythritol, and dipropylene glycol. This product is engineered to deliver consistent performance as a key intermediate or additive in demanding industrial formulations. It is primarily sought by manufacturers in the coatings, adhesives, and specialty polymer industries for its ability to modify resin properties and enhance final product characteristics.

Application

• Alkyd Resin Modifier: Used to improve flexibility, drying time, and adhesion in alkyd-based surface coatings and paints.
• Polyester Resin Intermediate: Serves as a building block in the synthesis of unsaturated polyester resins for composites and laminates.
• Adhesive Formulation: Imparts tack and cohesion properties in pressure-sensitive and structural adhesive systems.
• Plasticizer & Stabilizer: Acts as a secondary plasticizer and stabilizer in various PVC and other polymer compounds.
• Ink Vehicle Component: Incorporated into resin vehicles for printing inks to regulate viscosity and film formation.
• Cross-linking Agent: Functions as a cross-linker in thermosetting polymer networks to enhance durability and chemical resistance.
