Broad product spectrum for optimal electronics protection

measurement with laser optics

The increasing digitization of our world is based on the increasing prevalence of high-performance electronics and the latest sensor systems. This demands more effective protection for these sensitive electronic components and sensors from a range of environmental influences. Only in this way can the functionality of electronics appliances, and the safety of their users, be maintained on a long-term basis. The requirements for such an optimal electronics protection system are many and stringent:


  • Protection from damp to fulfil impermeability guidelines in accordance with IP Codes or NEMA
  • Protection from mechanical stresses and infringement against vandalism and plagiarism
  • Micro-seals from 0.8 – 2 mm in cross-section for small-format parts
  • Listings under UL 50 / UL 50E (tightness) for the safety of electrical/electronic housings and devices

  • RoHS conformity (restriction of hazardous substances) in accordance with EU-guideline 2011/65/EU for the restriction of the use of certain dangerous substances in electrical and electronic devices
  • ATEX protection in explosion danger zones
  • Aging resistance, also under variable temperature
  • Electrostatic charge and heat dissipating at high temperatures
  • Electrical insulation of cables against leakage current
  • Good flow properties for the filling of complex cavities
  • Good adhesion on various surfaces
  • Low material stress, so that fine electronic wires do not tear, as well as vibration and shock resistance
