Methylhexahydrophthalic anhydride(MHHPA) serves as a curing agent for hot-cured epoxy resins in the electric/electronics industry. It is also utilized as a raw material in various applications, including polyurethane/polyester resins, adhesives, LEDs, outdoor high voltage castings and composites, automotive clear coats, insecticides, plasticizers, and antirust agents.


Electronic Applications:

Due to its specific properties, MHHPA is well-suited for electronic applications, particularly in high-performance LEDs, where it offers outstanding mechanical and electrical properties, along with excellent color retention.



MHHPA should be stored away from open flames or potential ignition sources and protected from moisture. Crystallization may occur in contact with air humidity, so properties should be checked before reuse.


Academic research on Methylhexahydrophthalic anhydride


Curing behavior and thermal properties of multifunctional epoxy resin with methylhexahydrophthalic anhydride

Yanfang Liu, Zhongjie Du, Chen Zhang, Congju Li, Hangquan Li, Published in Journal of Applied Polymer Science

The curing behavior and thermal properties of bisphenol A type novolac epoxy resin (bisANER) with methylhexahydrophthalic anhydride (MHHPA) at an anhydride/epoxy group ratio of 0.85 was studied with Fourier-transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), and thermogravimetry.


Biological monitoring of methylhexahydrophthalic anhydride by determination of methylhexahydrophthalic acid in urine and plasma from exposed workers

Christian H. Lindh, Bo A. G. Jönsson & Hans Welinder , Published in International Archives of Occupational and Environmental Health

To investigate whether methylhexahydrophthalic acid (MHHP acid) in urine and plasma can be used as a biomarker for exposure to methylhexahydrophthalic anhydride (MHHPA). The results indicate that MHHP acid in urine or plasma may be used for biological monitoring of the exposure to MHHPA.
