• Detailed Description:

  Cas No. :11070-44-3 Specs:light yellow transparent liquid
  1.Light color, pre-addition 0.5-3% tertiary amine accelerator (BDM A, DMP-30) basically
  unchanged. It is a light yellow transparent liquid, which can be used to cast light or natural
  solids.
  2. Low viscosity: the process of casting, sealing and impregnation is good. A large number
  of fillers can be added when casting to make the curing material perform well. When used for
  impregnation, it is easy to adjust it into suitable impregnation conditions. Laminaring is
  conducive to the affinity of the basics.
  3. Stable performance, low freezing point, long application period, can be stored for a
  long time at room temperature, which is convenient for pipeline transportation. It is conducive
  to production automation and adapts to cold areas.
  4. Low volatility, small heating loss, low toxicity, and only amine curing
  agents1/20~1/40.less irritating to human eyes and skin.
  5. Good mutual solubility. This product is mutually soluble with all epoxy resins, and the
  mixing viscosity is low.At the same time, the contraction and exothermic effect of the system
  are relatively low when heated and curing.Main uses：
  6.Small heating loss, small volume shrinkage of curing, high thermal deformation
  temperature, excellent mechanical and electrical properties, and small dielectric loss angle
  tangent(110℃).
