Hexahydro-4-methylphthalic anhydride(Cas 19438-60-9) Usage

Flammability and Explosibility	Nonflammable
Contact allergens	Methylhexahydrophthalic anhydride is an epoxy hardener, irritant to skin and mucous membranes. It is included in nondiglycidyl-ether-of-bisphenol-A epoxy resins. It can induce both allergic contact dermatitis and immunologic contact urticaria. It is structurally close to methyltetrahydrophthalic anhydride, which can also cause sensitization.
General Description	Methylhexahydrophthalic anhydride, a congener of phthalic anhydride, is utilized in the production of plastics, paints, and electronic components. It can potentially result in allergenic effects on humans upon exposure and cause immunological reactions.
