  •  Encapsulation of electronic components

ELASTOSIL® RT 563 is cured by adding Catalyst T37 for long pot lives and curing times, or Catalyst T40 for short pot lives and curing times.


The pot life is the period of time at 23 °C / 50 % rel. humidity during which the catalyzed mix to attain a viscosity of 100,000 mPa s and still be just pourable


Catalyst T 37 and T 40 act as solvents until curing is complete. Preliminary tests must therefore be carried out to ensure that they are compatible with the components.
