  CAS NO: 78-63-7

  Properties:

  Activation energy: 36.0kcal/mol 　　

  1min. Half life temp.: 192℃

  Flash point: 36℃

  SADT.: 80℃

  Alarm temp.: 75℃

  Application:

  FARIDA DHBP is used as curing agent for silicone rubbers, polyurethane rubbers, ethylene-propylene rubbers and other kinds of rubbers, as well as crosslinking agent for polyethylene and curing agent for unsaturated polyether.

  Compared with Di-tert-butyl peroxide and DCP, DHBP is less volatile and more stable. It is a very effective high temperature curing agent for vinylsiloxane rubbers with higher tensile strength and lower tensile stretch.

  Package and Storage:

  Packed in PE drums, N.W.: 25kg.

  Stored below 38℃.

  Keep away from direct sunlight, strong acids, reductive agents and violent shaking during transportation or storage.
