QSil 553 s is a 2-component, silicone elastomer system specially designed for electronic potting and encapsulation applications. It offers good protection against chemicals, environmental contamination, mechanical shock, vibration and impact damage. It can be employed in areas where low flammability is a prerequisite. This cured elastomer can be repaired. This component parts have relatively low viscosities and are readily mixed either by hand or machine. Typical applications are electrical insulator, application cars e.g. encapsulation of ABS control unit.
