Nickel

EMC Shield Nickel Colloids have been formulated to meet the strictest control of electrical interference both radiation and susceptibility. It is formulated with specially prepared nickel granules and conductive resins to provide a conductive layer when applied by RF Solutions, compatible on to plastic, resins and metal substrates for a wide range of products. The highly conductive shield when applied to specification provides an effective shielding against radiated radio and Electromagnetic interference (RFI & EMI) and in other application can act as a ground plane to protect against electrostatic discharge (ESD).
