  MTHPA (methyl tetrahydrophthalic anhydride)

  Our MTHPA is  widely exported to Russia ,used in Oil and gas pipelines, insulating rod, transformer

   

  Used in epoxy resin solidifying agent, adhesive as well as insecticides, plasticizers and rust preventative etc.
  
   
  
  1. It is an acid anhydride type curing agent with high performance. It has the typical performances as Methyltetrahydrophthalic anhydride MTHPA Cas11070-44-3 (to Russia used in Oil and gas pipelines, insulating rod, transformer ) : high purity, light color, low viscosity, low volatility, low toxicity, low heating loss, stable performances, long use life, low freezing point, and can be stored for a long time under room temperature.
  
   
  
  2. It has more excellent performances than that of Methyltetrahydrophthalic anhydride MTHPA Cas11070-44-3 (to Russia used in Oil and gas pipelines, insulating rod, transformer ) :colorless, transparent, basically unchanged color after being added accelerant.
  
   
  
  3.The appearance of final products is white;, good resistance to heat, especially under the temperature lower than 150°C, excellent mechanical and electric properties, excellent weatherability, not be affected by light and heat, good moisture resistance, high reaction activity, fast solidifying speed and short gelation time
