QSIL 553

Qsil 553

UL APPROVED RTV SILICONE POTTING COMPOUND / ENCAPSULANT

Qsil 553 Is a 2-component, silicone elastomer system specially designed for electronic potting applications.

It offers good protection against impact damage and can be employed in areas where low flammability is a prerequisite.

The cured product is a hard, medium to high modulus elastomer that can be repaired.

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
