ESD Coating FAQs and Guides

Understanding static control, coating behaviour and application selection

This guide answers common questions about ESD coatings, static-dissipative surfaces and how ProShieldESD is selected for real applications.

Rather than treating ESD control as a single product choice, the ProShieldESD coating platform is used to engineer controlled static behaviour directly into surfaces. This includes plastics, industrial equipment, work surfaces, packaging systems and hazardous environments.

For application-specific guidance, use the ProShieldESD solutions pages.

What is an ESD Coating?

An ESD coating is a surface-applied layer that controls electrostatic charge build-up and discharge behaviour. It is used to reduce contamination, improve handling stability and protect sensitive components.

ProShieldESD uses filler-free conductive polymer technology, where conductivity is built into the coating itself rather than added through carbon or metal particles.

How Does ProShieldESD Differ from Traditional ESD Coatings?

Conventional ESD coatings rely on conductive fillers such as carbon or metal particles. Performance depends on the continuity of these particle networks, which can vary with wear, ageing and environment.

  • Filler-based systems depend on particle distribution
  • Performance can drift over time or with humidity
  • Localised variation can occur across the surface
  • Hidden electrical failure may not be visible from surface appearance

ProShieldESD uses a homogeneous conductive polymer system, providing more stable and predictable surface behaviour.

For comparison, see conductive coatings vs conductive plastics.

Key point: Static control performance is defined by surface behaviour during use, not just material type or initial test results.

What Resistance Range is Required?

The correct resistance range depends on the application, environment and ESD control strategy.

  • Conductive: typically 104–106 Ξ©/sq
  • Static dissipative: typically 106–109 Ξ©/sq
  • Anti-static: typically above 109 Ξ©/sq

Most controlled ESD applications target static-dissipative behaviour, allowing safe and predictable charge decay without creating an excessively conductive surface.

What Materials Can Be Coated?

ProShieldESD can be applied to a wide range of substrates where coating adhesion and durability can be controlled.

  • Plastics and composites
  • Metals and coated surfaces
  • Foams and packaging materials
  • Wood and porous substrates
  • Floors, walls and equipment structures
  • Benches, racks, trolleys and facility surfaces

Suitability depends on preparation, environment, cleaning exposure, wear conditions and required ESD performance.

How Is the Right Coating Selected?

Selection is application-led rather than product-led. The coating chemistry and process route are selected based on real operating conditions.

  • Substrate type and surface condition
  • Wear, cleaning and handling exposure
  • Environmental conditions
  • Required resistance range
  • Application method and process constraints

See ProShieldESD chemistries for more detail. For a practical route through the main options, see How to Choose the Right Static Control Approach.

Can SCH Services Coat Parts for Customers?

Yes. SCH Services can support trials, samples, prototypes and repeat coating work through ProShieldESD subcontract coating services.

This is useful where customers need controlled ESD coating performance but do not want to invest immediately in coating rooms, extraction, process development or operator training.

ESD coating suitability depends on substrate, environment, resistance range, grounding strategy, cleaning regime, wear conditions and verification testing. Final performance must be confirmed through appropriate trials and qualification.
