\Structural formula

Physical and chemical properties:

  • High purity and light color: The color of MTHPA is light yellow and transparent. It can be directly produced or produced into various colors required.
  • 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: Longterm storage at room temperature.
  • Low toxicity: Toxicity is only onetwentieth to onefortyth of the amine curing agent.
  • Low volatility: Sealed preservation.
  • Low heating loss.
  • Good mutual solubility: MTHPA WNY1008 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: More suitable for pipelining, white encapsulation, moulding, pultrusion and interwinding.
