VOS free resins

The VOS free resins for impregnation have been developed over the last 15 years to minimize emissions into the atmosphere.
The high viscosity and the lower reactivity of low VOC (Volatile Organic Substance) content resins generally means that the impregnation and curing cycles have to be set up very accurately.
Ideal for:

  • immersion impregnation at atmospheric pressure
  • trickle impregnation
  • roll dip/roll through impregnation
  • UV +Joule heating impregnation
  • vacuum impregnation
  • vacuum pressure impregnation

DOLPHON CC-1115 is a one-component thixotropic epoxy resin formulated for vacuum pressure impregnation in which good penetration and high material retention is required.

Its most important features are:

  • Excellent moisture resistance
  • Good penetration and reduced dripping during curing
  • Good electrical and mechanical properties
  • Good thermal shock resistance
  • High flash point
  • Good tank stability
  • Solvent free

DOLPHON CC-1118-LV is a thixotropic one-component epoxy compound suitable for the vacuum impregnation of electrical equipment in which excellent electrical characteristics at high temperature, low corona discharge and maximum resistance to chemical agents are required.
DOLPHON CC-1118-LV impregnates and encapsulates at the same time, thereby ensuring excellent penetration and good external coverage. This product makes it possible to impregnate equipment that has been preheated up to 60°C in order to improve penetration and shorten the treatment cycle without damaging the stability of the resin.
The main advantages of DOLPHON CC-1118-LV are:

  • Exceptional moisture resistance. Motors impregnated with DOLPHON CC-1118-LV pass the total immersion tests required by the US Navy according to specification MIL-M-17060E (200h of salt water operation)
  • Excellent electrical properties at high temperatures
  • Thixotropic – High and low viscosity with the same resin
  • Penetrates through several layers of mica tape
  • Complete covering with minimal dripping
  • Greater resistance to the corona discharge effect
  • Exceptional tank stability – Cooling not required
  • Formaldehyde free
  • EN-45545-2 approved
