The problem on site
Electronics manufacturing plants, testing laboratories, and cleanroom facilities often face a critical hurdle during plant commissioning or client audits: the floor fails static resistance tests. A contractor may have delivered a smooth, clean, and durable resin finish, yet the testing instruments show improper electrical resistance values across the surface.
When an electronics plant floor fails electrostatic discharge testing, production lines cannot safely start. Electrostatic charges that accumulate on personnel, tools, and trolleys remain on the surface rather than safely bleeding away. If an electrostatic discharge occurs near sensitive electronic components, integrated circuits, or sub-assemblies, the sudden spark can cause latent defects or direct component failure. For facility owners and site engineers, this leads to rejected handover inspections, delayed operations, and costly project overruns.
Why it happens
The primary reason for failed static tests is that conventional epoxy and polyurethane floor coatings act as electrical insulators. Standard polymer floors are formulated to provide seamless protection, chemical resistance, and compressive strength, but they naturally possess high electrical resistivity. As workers move across an insulated floor or push trolleys with synthetic wheels, triboelectric charging generates static electricity. Because the resin layer resists the flow of electrical current, there is no direct or controlled path to earth.
In other cases, an antistatic or static-dissipative coating may have been applied, but the system fails due to errors in design or installation. Common reasons for failure on site include:
- Omission of a conductive primer: Applying a dissipative topcoat directly over an insulating primer breaks electrical continuity.
- Improper copper grid installation: If the copper tape layout is spaced too far apart, torn during application, or isolated from the conductive layer, charges cannot travel horizontally across the floor.
- Disconnected earth terminals: The copper grid must connect directly to the facility earthing system. If these connections are missed, loose, or untied to earth pits, the charge remains trapped within the floor plate.
- Incorrect layer build-up: Excessive film build of non-conductive layers or incorrect mixing ratios can insulate conductive additives, preventing them from forming a continuous dissipative network.
How Space Arc Engineering approaches it
Space Arc Engineering works with builders, industrial flooring contractors, and site engineers as an authorised project distributor and technical solution provider. We do not treat resin flooring as merely a drum of material delivered to your site gate. Resolving electrostatic discharge issues requires an integrated flooring and grounding strategy.
When you consult Space Arc Engineering for an ESD antistatic epoxy flooring requirement, our team assists you in selecting the correct specification based on your facility operations. We review the operational conditions, such as wheel types, mechanical loads, cleanroom classifications, and grounding points. We supply the materials alongside clear installation methodologies, helping your execution team understand the relationship between concrete preparation, copper tape layout, conductive primer application, and the final dissipative topping.
By coordinating the technical requirements before application begins, Space Arc Engineering helps project teams avoid installation errors, protect their schedules, and ensure that the finished floor meets the required static-dissipative performance standards during facility sign-off.
The system we supply
To provide reliable static control in sensitive industrial environments, Space Arc Engineering supplies Fosroc Nitoflor SL3000 UT ESD, manufactured by Fosroc. This system is a static-dissipative seamless resin floor screed developed for cleanrooms, electronics production areas, and technical assembly spaces.
The Fosroc Nitoflor SL3000 UT ESD system offers distinct advantages for industrial projects:
- Designed to dissipate static charge: The formulation incorporates conductive elements that allow static charges to safely dissipate through the floor to ground, helping to safeguard sensitive electronics and instrumentation from electrostatic hazards.
- Seamless, easy-to-clean finish: Cleanroom environments require hygienic surfaces that do not harbor dust, contaminants, or process chemicals. The seamless nature of the system prevents dirt collection at joints and simplifies regular cleaning routines.
- Installed with an earthing arrangement: The system is designed to work as an integrated assembly comprising a dedicated primer, an earthing network incorporating copper tape connected to facility earth points, a conductive intermediate layer, and the static-dissipative topping.
- Mechanical durability: Engineered to withstand foot traffic, transport trolleys, and regular industrial movement typical of modern electronic manufacturing plants.
As an authorised distributor, Space Arc Engineering ensures that the complete material system manufactured by Fosroc is supplied with genuine components, full batch traceability, and manufacturer-recommended application literature.
What to check before you order
Before placing an order for ESD antistatic epoxy flooring, site engineers and project managers should conduct a thorough site evaluation. Reviewing these key parameters ensures smooth execution on site:
- Substrate moisture: Resin flooring requires a dry, sound concrete base. Check the concrete substrate for residual moisture and ensure a suitable damp-proof membrane is active below the slab.
- Mechanical surface preparation: The concrete base must be free of laitance, oil, curing compounds, and loose debris. Captive shot-blasting or mechanical diamond grinding is necessary to provide an open profile for proper bonding.
- Earth connection points: Coordinate with the site electrical contractor to identify earth pit connection points or grounding busbars around the perimeter of the room before laying the copper grid.
- Movement and expansion joints: Structural movement joints in the concrete must be brought through the ESD floor system. Coating over active expansion joints can lead to cracking and continuity breaks in the earthing grid.
- Ambient conditions during application: Resin systems are sensitive to temperature and ambient relative humidity during mixing and curing. Confirm that the room environment meets the application guidelines set by the manufacturer.
