Electromagnetic Sheilding Adhesives – Achieve Optimal Device Usage

Table of Contents

With the growing proliferation of wireless devices, we have come to realise that it is increasingly essential to deal with electromagnetic waves that radiate the same frequency spectrum and cause electromagnetic interference. Devices that emit radio frequencies require effective electromagnetic shielding to limit the propagation of their interference to nearby components and to protect the final device from performance degradation. As electronics evolve towards miniaturisation, lower weight and higher speeds, these challenges become more and more significant, as conventional shielding methods have functional and operational limitations.

An optimal solution we propose for interference protection is the use of an electromagnetic shielding adhesive.

What Are Electromagnetic Shielding Adhesives?

Connectivity, reliability and stringent safety standards increase the need for high-performance electromagnetic interference (EMI) shielding solutions. Electromagnetic shielding adhesives are products designed to decrease the influence of electromagnetic fields and radiation on a device or object. The shield uses a barrier made of conductive material whose purpose is to protect the devices from electromagnetic interference and to attenuate the transmission of EMI outside the device.

A very effective electromagnetic shielding adhesive is Dowsil ™ EC-6601, This electronic silicone adhesive is capable of withstanding many compression and tension cycles and maintains a strong conductive path, making it ideal for 5G radar, camera and base station applications.

DOWSIL ™ EC-6601; winner of the 2020 R&D 100 Award, is one of the best electronically conductive adhesives. DOWSIL ™ EC-6601 is a stable and durable electromagnetic shielding adhesive. Compared to other products, it shows stronger adhesion, more conductivity, better material strength, higher flexibility and longer shelf life.

This unique adhesive offers:

  • Strong shielding over a wide frequency range
  • Elongation greater than 150% allows flexibility in the joints
  • Strong adhesion to many substrates
  • Reliable performance, with mechanical properties and mechanical and conductive properties
  • Excellent corrosion resistance
