maleic anhydride

Main Applications: Polyester Resins & Plastics – a key ingredient in unsaturated polyester resins (for fiberglass composites) and in modifying polymers (e.g. maleated polyolefins as coupling agents for composites), Coatings & Adhesives – used in alkyd and epoxy-resin formulations and as a curing agent or adhesion promoter in certain adhesives and sealants (improves bonding to polyolefins and crosslinking density), Construction Materials – used in making plasticizers, curing agents, and additives for construction products (and in paper sizing and water treatment chemicals). Overall, it’s central to coatings, adhesives, and polymer manufacturing for improved material performance.
