MTHPA - Model WNY1002 -Anhydride Curing Agent

SHARE

Methyl tetrahydrophthalic anhydride (MTHPA, MeTHPA) is a high performance product of anhydride curing agent. Our MTHPA products of WNY-1002 series has excellent performance when reacting with epoxy resins. Its characteristics include high purity, light color, low viscosity, low volatility, low toxicity, low heating loss, stable performance, long pot life, and freezing point. It can be long-term stored at low and room temperature. The specific characteristics are as follows:

  • Chemical Name: Methyl tetrahydrophthalic anhydride (MTHPA, MeTHPA)
  • Specification: WNY1002
  • Molecular formula: C9H10O3
  • Molecular weight:166.178
  • CAS No.:26590205  11070443
  • EC：2478301
  • Structural formula:

Physical and chemical properties:

  • High purity and light color: Light yellow and transparent. Epoxy resin products can be directly produced or produced into various colors required.
  • Low viscosity: Good processing properties for winding, molding, casting, bonding, potting, lamination, dipping and impregnation. A large amount of filler can be added during casting to make the cured product excellent in performance.
  • Stable performance, low solidifying point, long application period: sealed preservation and longterm storage at room temperature.
  • Low toxicity: Toxicity is only onetwentieth to onefortyth of the amine curing agent.
  • Low volatility.
  • Low heating loss.
  • Good mutual solubility: This product 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 moulding, pultrusion and interwinding.
