  Performance characteristics
  Colorless transparent liquid, basically unchanged after adding an accelerator, the epoxy cured product is white in color; the complex composed of aliphatic epoxy resin has low viscosity, long application period, and the cured product has good heat resistance and high temperature 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 and is resistant to aging. The molecular structure is relatively non-polar, and the cured product has good moisture resistance; it has high reactivity, can be cured quickly, has a short gel time, and the cured product has a high thermal deformation temperature.
  Main uses
  1. Epoxy resin curing agent: It can be used for the impregnation of coils of electrical equipment, the casting of electrical components and the potting of semiconductor materials, such as the casting of outdoor insulators, light-emitting diodes (LED), ignition coils, special-purpose capacitors, transformers, motors, sports and entertainment equipment, etc., which require resistance to outdoor ultraviolet light and good moisture resistance.The field.
  2. Epoxy composite materials: together with fiber reinforced materials, their application in lamination, centrifugal casting, pultrusion, etc. has received more and more attention. Such as pressure cylinders, pressure pipes, fishing rods, golf clubs, etc.
  3. Adhesive: The refractive index of the aliphatic epoxy adhesive made of MHHPA is similar to that of optical glass. After curing, the internal stress is small, the bonding strength is high, no discoloration, and aging resistance. It is suitable for bonding large-area optical parts.
  Packaging and storage
  Packed in 25 kg plastic drums, 220 kg iron drums, and IBC drums, this product has stable performance. During storage and transportation, pay attention to airtight, moisture-proof, fire-proof, and waterproof. Store in a dry and ventilated warehouse and store at room temperature for one year without deterioration. If the storage is improper, crystallization or turbidity will occur after moisture absorption, and it needs to be opened and heated again to restore it to its original state without affecting the original performance.
