Product Introduction

Static-dissipative epoxy flooring manages electrostatic charge within a controlled resistance band rather than providing the lowest possible path to earth. This controlled discharge is suited to electronics production, semiconductor handling and instrument rooms where sudden ESD events can damage components. Conductive additives extend through the epoxy thickness, while a compatible primer and grounding arrangement complete the electrical circuit. Final performance is evaluated as a floor-footwear-person system because footwear, humidity, cleanliness and test equipment all influence measured resistance and body voltage.

Key Features

The designed 10⁶–10⁹ Ω resistance range dissipates charge without treating the floor as a highly conductive metal surface.

Through-thickness conductive components retain static-control function as the top surface experiences normal wear.

A smooth non-porous finish supports particle control and repeated cleaning around sensitive assembly operations.

Compatible ESD footwear can be integrated with the floor to limit charge generated by walking personnel.

Customer Product Concerns

An ESD floor is only effective when resistance, body voltage, footwear and grounding work together under the actual room conditions.

A charge too small for personnel to feel still damages an exposed electronic component.The dissipative epoxy and compatible footwear continuously reduce body voltage during movement.

Some static-control coatings change resistance sharply as humidity falls.Conductive material distributed through the resin provides a more stable path than a surface-only treatment.

A floor passes a point resistance test but fails when evaluated with production footwear.Commissioning includes floor resistance and person-floor-footwear measurements across representative locations.

Dark conductive floors make small components and contamination hard to see.Pigmented dissipative formulations provide practical light gray, medium gray and selected color options.
