Application Case Study

ESD Conversion of Label Printers

Applying controlled ESD behaviour to desktop and industrial label printers used near sensitive electronics.

The problem

Label printers are commonly positioned at production lines, test stations, and packing areas. While essential for traceability and logistics, their plastic housings and frequent human interaction can introduce uncontrolled static charge close to ESD-sensitive devices.

Conventional ESD programs often overlook label printers, assuming distance or grounding is sufficient. In practice, repeated handling, paper movement, and operator contact can create static risk.

The substrate

Label printer enclosures are typically made from ABS or polycarbonate plastics, sometimes combined with painted metal panels. These surfaces are electrically insulating and prone to static accumulation.

Why replacement was not viable

  • Limited availability of purpose-built ESD label printers
  • High replacement cost for industrial-grade printers
  • Disruption to validated printing and traceability systems
  • Inconsistent compliance when standard devices are reintroduced

The ProShieldESD solution

ProShieldESD was applied as a thin, uniform coating to the external surfaces of label printer housings. The coating creates a controlled ESD surface while preserving ventilation, access panels, and mechanical tolerances.

The two-part system provides strong adhesion to plastic and painted metal substrates, delivering humidity-independent ESD behaviour suitable for continuous production environments.

Performance outcome

  • Surface resistance within the ESD dissipative range
  • Uniform charge dissipation across the printer housing
  • No impact on printing quality, sensors, or connectivity
  • Stable performance under frequent operator interaction

Standards alignment

The converted label printers support ESD control programs aligned with IEC 61340 and ANSI/ESD S20.20 requirements when deployed within grounded work areas.

Key benefits

  • Reduces ESD risk near production and packing stations
  • Avoids costly replacement of validated equipment
  • Maintains operational continuity and uptime
  • Easy to recoat or repair by in-house maintenance teams
