Methylhexahydrophthalic anhydride Chemical Properties,Uses,Production

Chemical Properties

colorless clear

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.

Preparation

Methyl hexahydrophthalic anhydride is produced from methyl tetrahydrophthalic anhydride by catalytic hydrogenation. It is a high-performance product among acid anhydride-type solidifying agent.

Definition

ChEBI: Methylhexahydrophthalic anhydride is a cyclic dicarboxylic anhydride that is the cyclic anhydride of methylhexahydrophthalic acid. It has a role as an allergen and a curing agent. It is a cyclic dicarboxylic anhydride and a tetrahydrofurandione.

storage

MHHPA must be stored away from open flames or other potential ignition sources, and should be protected from moisture, because it easy crystallizes when it's in contact with the humidity of the air. When some crystallization occurs, check the properties before reusing.
