Industrial Applications of 5-Norbornene-2,3-dicarboxylic anhydride
| Industry | Application | Process |
|---|---|---|
| Composites | Epoxy resin curing agent for high-performance composites, e.g., aerospace components and wind turbine blades | Heat-cured after blending with epoxy resin to form a three-dimensional network exhibiting high glass transition temperature (Tg) and superior thermal resistance |
| Electronic Encapsulation | Curing agent for epoxy molding compounds (EMCs) used in semiconductor packaging | Mixed with bisphenol-A epoxy resin and fillers, then injection-molded and thermally cured to yield low moisture absorption and high dimensional stability |
| Coatings | Crosslinker for high-temperature and chemical-resistant coatings | Reacted with hydroxyl- or amino-based resins via thermal curing to produce industrial protective coatings suitable for high-temperature applications such as engine components |
| Adhesives | Curing component for high-performance structural adhesives | Thermally cured with epoxy matrix resins at 120–180 °C to achieve high shear strength and aging resistance |
| Plasticizer Modification | Heat-stabilizing plasticizer intermediate for polymers such as polyvinyl chloride (PVC) | Converted via esterification into nadic anhydride derivatives (e.g., trimethylolpropane trinadate), then compounded and plastified with PVC |
