Applications of 935-79-5
| Industry | Application | Process |
|---|---|---|
| Electronics & Electrical | Epoxy resin curing agent | Used as an anhydride-type curing agent in the curing of encapsulants, potting compounds, and insulating materials for electronic components, imparting excellent thermal resistance, electrical insulation, and mechanical strength. |
| Electronics & Electrical | Raw material for electronic-grade epoxy molding compound (EMC) | Reacted with polyols or phenolic resins to produce epoxy molding compounds for semiconductor packaging, enhancing moisture resistance and thermal stability of the packaging material. |
| Composites | Unsaturated polyester resin modifier | Used to produce modified unsaturated polyester resins, improving weather resistance, thermal stability, and mechanical properties—commonly applied in fiberglass-reinforced plastic (FRP) manufacturing. |
| Coatings Industry | Raw material for alkyd resins | Serves as a dibasic acid feedstock in alkyd resin synthesis for coatings, enhancing film hardness, gloss, and drying speed. |
| Coatings Industry | Curing agent for powder coatings | Used in combination with hydroxyl-functional polyester resins as a crosslinking curing agent for powder coatings, delivering good flow leveling and resistance to yellowing. |
| Pharmaceutical Chemicals | Pharmaceutical intermediate | Employed in the synthesis of specific drug molecules or pharmaceutical intermediates, leveraging its tetrahydrophthalic ring structure for subsequent chemical modification. |
| Fine Chemicals | Plasticizer production | Esterified to produce tetrahydrophthalic anhydride-based plasticizers, improving flexibility and processability of polymeric materials. |
| Adhesives | Curing agent for epoxy adhesives | Formulated into heat-resistant epoxy adhesives for structural bonding of metals or ceramics under high-temperature conditions. |
