SPECIFICATION SHEET OF MTHPA
Product Name: Methyl tetra-Hydro Phthalic Anhydride (MTHPA)
Product number: JC-1018
Molecular formula: C9H10O3
Molecular weight: 166.178
CAS No.: 11070-44-3
Structural formula：
Performance Characteristics:
High purity, light color: can be directly made or made into a variety of color epoxy resin products.
Low viscosity: Excellent processing properties for winding, molding, casting, bonding, potting,
lamination, dipping and impregnation. A large amount of additive can be added during casting to
make the cured product excellent in performance.
-Stable performance, low solidifying point, long application period: Long-term storage at room
temperature.
-Low toxicity: Toxicity is only one-twentieth to one-fortyth of the amine curing agent.
-Low volatility: Sealed preservation.
-Low heating loss.
-Good mutual solubility: MTHPA can be miscible with all epoxy resins, the mixing viscosity is
low, and the shrinkage rate of the system is small when heated and cured.
-Application: It is used as an epoxy resin curing agent and is widely used in electronic
components, LED digital tube potting glue, glass fiber reinforced plastic composite materials,
wind power blades, auto parts, dry transformers, high-voltage switches, high-voltage capacitors,
transformers, home appliance capacitors, power capacitors and resistors, integrated circuit
impregnation, pouring, winding and other fields...
