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
