Feature

Methylhexahydrophthalic anhydride is a high-performance product in acid anhydride curing agents, in addition to the general performance of methyltetrahydrophthalic anhydride (high purity, light color, low viscosity, low volatility, low toxicity, low heating loss, stable performance, suitable for Long period, low freezing point and long-term storage at room temperature), in addition to methyl tetrahydrophthalic anhydride has more superior performance, such as color and colorless transparent liquid, after adding accelerator does not change color, epoxy cured white color; Good heat resistance, especially at 150 °C, epoxy cured products have excellent mechanical and electrical properties. The molecular structure does not contain double bonds, and the cured epoxy resin has good weather resistance and is not affected by light and heat. The molecular structure is relatively non-polar, and the cured product has good moisture resistance; high reactivity, fast curing, and short gel time, which is conducive to the immersion molding of large motors.

Description

Methylhexahydrophthalic anhydride is an excellent organic solvent. It is mainly used as a solvent for oils and fats, extractants, electrolytic solvents for lithium batteries, chlorine-based solvent stabilizers, pharmaceutical intermediates, and raw materials for co-formaldehyde, silk finishing agent, sealant material, epoxy curing agent.

Usage

1. As a curing agent for epoxy resin, methylhexahydrophthalic anhydride is a heat curing type anhydride curing agent, mainly used in the electrical and electronic fields. It has a low melting point, a low viscosity compound with an alicyclic epoxy resin, a long pot life, and high heat resistance of the cured product. Methylhexahydrophthalic anhydride has better electrical properties and higher heat distortion temperature than methyltetrahydrophthalic anhydride, so this product provides raw materials for the upgrading of the electronic and electrical industry. Methylhexahydrophthalic anhydride can be used for impregnation of electrical equipment coils and casting of electrical components and sealing of semiconductors, such as casting outdoor insulators, light emitting diodes (LEDs), ignition coils, special purpose capacitors, transformers, motors, sports and entertainment equipment, etc. Areas with good light and moisture resistance.

2. As an epoxy-based composite material, methylhexahydrophthalic anhydride is more and more widely used in high-performance composite materials. It is combined with fiber-reinforced materials such as pressure gas cylinders, pressure pipes, fishing rods, golf clubs, etc. Pressure, centrifugal casting, pultrusion and other applications are getting more and more attention.

3. As an adhesive, the refractive index of alicyclic epoxy adhesive made of methylhexahydrophthalic anhydride is similar to that of optical glass. After curing, the internal stress is small, the bonding strength is high, the color is not changed, and it is resistant to aging. It is suitable for bonding large-area optical parts.
