Methyltetrahydrophthalic anhydrideProperties

Methyl tetrahydrophthalic anhydride is of high purity and light color. It can be directly prepared or prepared into epoxy resin products of various colors required.

Low Viscosity: Casting, filling and impregnation process is good. When casting, a large number of fillers can be added, so that the properties of cured products are excellent.

It has stable performance, low freezing point, long service life and can be stored at room temperature for a long time.

Low volatility: low toxicity; low heating loss, toxicity is only one twentieth to one fortieth of amine curing agent.

Mutual solubility: This product can be soluble with all epoxy resins, low mixing viscosity, while heating curing system shrinkage is small.Description of necessary first-aid measures

Methyltetrahydrophthalic anhydride Application

This product is an essential new fine chemical product in electronics industry and electromechanical industry. It is widely used in filling, casting, encapsulation, lamination, moulding, bonding, winding and other processes. Epoxy resin curing agent: electrical and electronic insulation material (VPI motor impregnation/dry transformer/transformer pouring/high voltage switch/capacitor), LED digital tube filling glue, ornament coating (crystal dropping plastic polishing glue), FRP composite material (CNG cylinder/wind turbine blade/electrical bushing).
