Description

2-Butenedioic Acid (2E)-, Polymer With 2,5-Furandione, 1,3-Isobenzofurandione And 1,2-Propanediol is a specialized polymeric resin derived from maleic anhydride, phthalic anhydride, and propylene glycol. This compound matters as a versatile intermediate for producing high-performance alkyd and polyester resins, offering excellent durability and chemical resistance. It is primarily needed by manufacturers in the coatings, adhesives, and composite materials industries seeking to enhance product performance.

Application

• Primary raw material for the synthesis of alkyd resins used in industrial and decorative paints and coatings.
• Key component in the production of unsaturated polyester resins (UPR) for fiberglass-reinforced plastics (FRP) and composite materials.
• Used in formulating adhesives and sealants requiring strong bonding and environmental resistance.
• Intermediate for plasticizers and modifiers to improve the flexibility and processing of polymers.
• Base for specialty coatings applied in automotive, marine, and construction sectors for corrosion protection.
• Potential use in the synthesis of polymeric dispersants and grinding aids for pigment and filler systems.
