Conductive Coating

Conductive Coating is an excellent way to provide EMI Shielding to plastic enclosures. As a secondary process it provides a means to add coating later in production, allows rapid prototypes to be shielded and can provide varying performance dependent on requirement.

Conductive coatings exhibits excellent adhesion and can be applied to most plastics (including ABS, PC, PBT, PLA) and with the use of specialised adhesion promoters even low surface-energy materials like Polypropylene, and Nylon can be coated.

  • Excellent Coverage

    Complex Geometry

    Wet-spray coating allows complex internal geometries to be coated with minimal tooling costs.

  • Light Weight

    Low Weight

    With possible coating thickness below 12.5μm strict weight restrictions can be achieved with plastic enclosures.

  • Highly Conductive

    High Conductivity

    Surface resistivity can be < 0.015 Ohm/square with excellent attenuation offering outstanding shielding performance.

Why Conductive Coating?

  • No Expensive Metalwork

    Provides excellent shielding performance on plastic moulded, SLA or FDM enclosures. Eliminating the need for costly machining.

  • Saves Weight

    A very low film thickness when applied to plastics allow for significant weight savings.

  • Excellent EMI Protection

    Silver Coating provides shielding satisfying the most rigorous EMC testing requirements.

  • In-House Mask Tooling

    Our capability to produce in house mask tools provide very short lead times on complicated enclosures.


  • Excellent Surface conductivity
  • Dry thickness can be < 12.5μm
  • Excellent adhesion to most substrates
  • Compatible with sensitive plastics
  • Adhesion Promoter can be used on difficult substrates
  • Good scratch and heat resistance
  • Range of products to suit requirements

FDM Tool Manufacture

In-House Tool Manufacture

At Uvox we produce in-house tooling for nearly all conductive coating applications. Enabling rapid prototyping and revisions throughout the design process with minimal tooling and re-tooling costs. We use traditional techniques combined with cutting-edge additive-manufacture to provide a solution tailored to each job.
