Hexahydrophthalic anhydride (HHPA)
1, can make the epoxy resin has good mechanical properties, electrical properties and chemical corrosion resistance. Epoxy products cured with hexahydrophthalic anhydride have a lower shrinkage rate than other curing agents, which means that during the curing process, the size of the product changes less and can better maintain shape and accuracy. For example, in the packaging of electronic components, this low shrinkage characteristic can effectively prevent damage to components caused by the shrinkage of packaging materials.
2, has good compatibility, can be well compatible with a variety of polymer materials such as polyvinyl chloride (PVC), polyester, etc., will not appear phase separation phenomenon. At the same time, it can also improve the cold resistance of polymer materials, so that the material can still maintain good flexibility in low temperature environment.
3, can effectively reduce the crystallinity of polyester resin, improve the transparency and flexibility of the resin. At the same time, it can also improve the water resistance and chemical resistance of polyester resin.

Applications:
Epoxy resin curing agent: widely used in electronic and electrical fields, such as manufacturing circuit boards, electronic components packaging materials; In the coating industry, it is used to prepare high-performance anticorrosive coatings and insulating coatings; In the field of composite materials, it is used to produce fiber reinforced composites, such as glass fiber reinforced epoxy resin composites, which can be used to manufacture aerospace components, automotive parts, sports equipment, etc.
Plasticizer: In the plastics industry, it is often used to manufacture soft PVC products, such as wire and cable skins, hoses, soles, etc., to improve the flexibility and processing performance of these products.
Polyester resin modifier: widely used in coating, ink, adhesive and other fields. For example, the use of modified polyester resin in coatings can improve the gloss, adhesion and weather resistance of the coating; In the ink can improve the fluidity of ink and printability; In the adhesive can enhance the adhesive bond strength and flexibility.
