The problem

Metal wardrobes and storage cabinets are commonly used in electronics manufacturing, laboratories, and controlled areas for storing tools, components, garments, and personal items. Although metal structures can be grounded, painted doors, shelves, and handles often remain electrically isolated.

Repeated opening, closing, and handling can result in inconsistent ESD behaviour, especially when cabinets are located near ESD-sensitive workstations.

The substrate

Powder-coated or painted steel wardrobes and cabinets, including doors, shelves, frames, and handles.

Why replacement was not viable

• High cost of purpose-built ESD storage cabinets
• Long lead times for specialised furniture
• Large installed base already deployed
• Operational disruption during replacement

The ProShieldESD solution

ProShieldESD was applied as a thin, uniform coating to the painted and accessible surfaces of the wardrobes, including doors, shelves, and handles. The coating creates a continuous dissipative surface while maintaining mechanical durability.

When combined with proper grounding of the cabinet structure, the system delivers predictable and uniform ESD behaviour during daily use.

Performance outcome

• Controlled surface resistance across all coated areas
• Uniform charge dissipation during door and drawer operation
• No impact on cabinet function or storage capacity
• Durable performance under repeated use

Standards alignment

The converted wardrobes support ESD control programs aligned with IEC 61340 and ANSI/ESD S20.20 requirements when integrated into grounded ESD-controlled areas.

Key benefits

• Upgrades existing cabinets into ESD-safe storage assets
• Improves ESD consistency near workstations
• Avoids replacement cost and downtime
• Easy to maintain or recoat if damaged
