EMI Coating protects electronic equipment
EMI Shielding - EMI Coating - EMC
Today, various types of Electronic equipment are produced with electromagnetic interference (EMI) shielding to ensure electromagnetic compatibility (EMC). Such properties are important factors for the functionality of e.g. electronic communication equipment.

Polyteknik can provide metallic EMI shielding layers with excellent adhesion and long term durability, incorporated in housings of different plastic compositions. As a result of the controlled layer thickness the weight of the final product is not affected. This yields a coating special suitable for lightweight products.

Some common shielding coating materials are Silver, Gold, Copper, Nickel, Stainless Steel and Aluminum.

Some of the benefits of Polyteknik PVD EMI coating are:

- Outstanding adhesion and conductivity provides excellent EMI/RFI/ESD shielding
- Repeatability of coating conductivity and thickness
- Thin film coatings will not interfere with product assembly
- More consistent coverage and resistivity than conductive paint or other conventional processes
- Uniform coverage on complex substrates
- Coatings can be applied to most plastics
- Environmentally friendly process
