Description
ACC EE RTV 2005 is a readily pourable, white, two component silicone elastomer which cures on addition of the catalyst to a resilient rubber.

Applications

  • Potting sensitive components to protect from vibration, high humidity or other harsh environmental conditions
  • Protective coating for pcb's
  • Protection for automotive electronics, control boxes, etc
  • Potting and sealing of cable joint assemblies

Catalysation and Cure
The recommended concentration of Curing Agent A is between 0.25% and 1% depending on the desired pot life and tack-free time. In general the pot life of ACC EE RTV 2005 catalysed with Curing Agent A will vary from about 3 hours at 0.25% catalyst to about 1 hour at 1%. The rubber will cure in approximately 24 hours to a hardness of approximately 40 °IRHD (measured on a test piece 12mm thick).
