• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.
• Effects of Short Term Exposure: The substance is irritating to the skin. The substance is severely irritating to the eyes.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.
• Uses: Methylhexahydrophthalic Anhydride(MHHPA) is a hardener for hot-cured epoxy resins in the electric/electronics industry as well as a raw material for polyurethane/polyester resins, adhesives, LEDs, Outdoor High Voltage Castings and Composites, automotive clear coats, insecticide, plasticizer and antirust. Due to its cycloaliphatic structure and the absence of aromatic bonds, metals or contaminants, MHHPA imparts inequivalent resistance to UV radiation and atmospheric agents. These characteristics make MHHPA particularly suited for electronic applications, such as high performance LEDs and for automotive clear coats. In addition, MHHPA exhibits outstanding mechanical and electrical properties, as well as excellent color retention.
