The component parts have relatively low viscosities and are readily

mixed in a simple 1:1 ratio

Industrial applications include:

  • Potting & encapsulation delicate electronic assemblies
  • PCB protection where thermal conductivity is required
  • Low viscosity to run around complex parts
  • Encapsulation when environmental protection is required
