QSil 553 Silicone Encapsulants

Adhesive Bonding Technology

2-Part Encapsulation and Potting Silicone - This 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. The cured elastomer can be repaired. The component parts have relatively low viscosities and are readily mixed either by hand or machine.

Key Features

  • 100% solids
  • no solvents
  • Long pot life
  • Low modulus and good elongation
  • UL94 V0 listed in file No. E205830

Application

  • Electrical insulator, application cars e.g. encapsulation of ABS control unit.
