Hexahydrophthalic anhydrideCAS85-42-7

 Usage

Hexahydrophthalic anhydride (HHPA) is an important organic chemical raw material with relatively extensive applications:

• In the field of coatings: It can be involved in the preparation of various high-performance polyester resins. The coatings made based on these resins possess excellent adhesion, chemical corrosion resistance, and hardness. In industrial protective coatings and automotive topcoats, the use of polyester resins containing hexahydrophthalic anhydride can not only resist the erosion of external acids, alkalis, and solvents but also maintain the brightness and integrity of the coating for a long time, providing long-term protection for the coated objects.
• In terms of electronic and electrical materials: It is widely used in the production of epoxy resin curing agents. After being cured by hexahydrophthalic anhydride, the epoxy resin forms materials with outstanding insulation properties and good thermal stability. In printed circuit boards and electronic packaging materials, it can accurately ensure the stable operation of electronic components and prevent electrical failures such as short circuits and leakage.
• In the application scenarios of composite materials: As a key raw material for unsaturated polyester resins, when combined with reinforcing materials such as glass fibers, the fiberglass composite materials produced are high in strength and light in weight. They are commonly used in the manufacturing of aerospace, ship, and automotive parts, such as aircraft interior panels, ship hulls, and automotive body coverings. While meeting the requirements of mechanical properties, they also achieve the lightweight of components.
• In the adhesive industry: Hexahydrophthalic anhydride can adjust the curing characteristics and bonding strength of adhesives. It enables the adhesives to have not only good initial tack but also long-lasting adhesion. It is widely applied to the bonding between different materials such as metals, plastics, and wood. For example, the gluing processes in furniture assembly and electronic device assembly cannot do without it.
