An anti-static spray is a topical chemical solution applied to surfaces, materials, or equipment to reduce electrostatic charge generation, lower surface resistivity, and prevent electrostatic discharge (ESD) events that damage static-sensitive electronic components.
Anti-static sprays work by depositing a thin conductive or static-dissipative layer onto a treated surface. This layer provides a controlled path for electrostatic charge to dissipate safely, rather than accumulating and discharging uncontrollably onto static sensitive electronic devices.
They are used across electronics manufacturing, PCB assembly, medical device production, packaging, and any industrial environment where electrostatic discharge poses a risk to product quality, personnel safety, or operational continuity.
Electrostatic charge builds up when two materials come into contact and separate, a process called triboelectric charging. In industrial environments, this happens constantly: operators walking across floors, components moving through conveyors, packaging being applied and removed, and materials being handled on workbenches.
The consequences are measurable and costly:
Component damage. A single ESD event can cause catastrophic or latent damage to ICs, MOSFETs, and other static-sensitive devices. Latent damage is particularly problematic; the component continues to function but with degraded reliability, leading to field failures weeks or months later.
Contamination and dust attraction. Charged surfaces act as magnets for airborne particles, dust, and bacteria. In cleanroom and PCB assembly environments, this contamination directly affects soldering quality, optical inspection accuracy, and process yields.
Process disruption. In packaging, printing, and converting operations, static charge causes material jamming, sheet slippage, misfeeds, and adhesion failures, all of which reduce throughput and increase waste.
Fire and explosion risk. In environments where combustible vapours, solvents, or fine dust are present, an uncontrolled electrostatic discharge can act as an ignition source creating serious safety hazards under ATEX-classified conditions.
Data and system errors. ESD events near static-sensitive electronics including automated test equipment and data processing systems can cause memory errors, data corruption, and system resets without any visible physical damage.
Static charge does not need to be visible or perceptible to cause damage. ESD events as low as 100 volts can destroy many modern semiconductor devices far below the human perception threshold of approximately 3,000 volts.
Anti-static sprays function through one or more of the following mechanisms depending on their formulation:
Hygroscopic moisture absorption. Many anti-static agents are hygroscopic; they attract trace moisture from the surrounding air and retain it on the treated surface. This moisture layer increases surface conductivity, providing a path for charge to dissipate. This is why surface resistivity is typically lower at higher relative humidity.
Conductive polymer coating. Higher-performance formulations deposit a thin layer of conductive or static-dissipative polymer onto the substrate. This coating remains effective even at very low relative humidity below 15% RH unlike humidity-dependent formulas.
Ion neutralisation. Some sprays work in conjunction with ionisation to neutralise existing surface charge at the point of application, providing immediate dissipation before the protective coating takes effect.
Surface resistivity modification. The applied coating changes the electrical classification of the treated surface. Untreated plastics and insulators typically have surface resistivities above 10¹² ohms, well into the insulative range. Effective anti-static sprays reduce this to the static-dissipative range of 10⁶ to 10¹¹ ohms, or conductive range below 10⁶ ohms, depending on formulation strength.
| Parameter | Insulative Surface | Static-Dissipative | Conductive |
| Surface Resistivity | >10¹¹ Ω | 10⁶ – 10¹¹ Ω | <10⁶ Ω |
| ESD Risk | High | Controlled | Grounded path |
| Anti-Static Spray Target | Yes | Maintained | Enhanced |
Electrostatic decay time is the rate at which a charged surface returns to near-zero volts after treatment. High-quality Staticide® formulations achieve static decay in under 2 seconds, meeting MIL-B-81705 and Federal Test Standard 101, Method 4046 criteria.
Once applied, the protective layer persists from several weeks to several months depending on the substrate, traffic volume, and cleaning frequency. Coverage rates are predictable: 1 US gallon treats approximately 2,000 sq. ft. on non-porous surfaces.
Anti-static sprays are deployed across a broad range of industrial and manufacturing contexts. The application environment determines which product type and formulation is appropriate.
Electronics manufacturing and PCB assembly. The highest-risk environment for ESD damage. Anti-static sprays are applied to workbenches, tote boxes, carriers, component trays, and non-ESD packaging materials. Every surface that contacts a static-sensitive device must be treated or inherently static-dissipative.
ESD Protected Areas (EPAs). Any designated EPA – as defined under IEC 61340-5-1 – requires all surfaces within it to meet resistivity specifications. Anti-static sprays maintain the ESD performance of mats, floors, benches, and equipment between scheduled replacements.
Automotive and avionics assembly. High-reliability sectors where latent ESD damage creates field failure risks in safety-critical systems. Anti-static treatment of assembly surfaces and storage materials is a compliance requirement, not a preference.
Medical device manufacturing. Static charge attracts particulate contamination and can damage static-sensitive electronic sub-assemblies. Anti-static sprays used here must be biocompatible, non-toxic, and leave no residues incompatible with cleanroom environments.
Packaging, printing, and converting. Static causes sheet jamming, label misapplication, web breaks, and ink adhesion failures. Anti-static sprays applied to rollers, guides, and substrates reduce process interruptions and waste.
Warehouse and logistics. Tote boxes, shelving, and plastic packaging materials accumulate charge during movement and handling. Treating these surfaces with anti-static spray reduces discharge events at goods-in and goods-out stages, protecting components throughout the supply chain.
Cleanrooms. Anti-static sprays rated for critical environments control both charge generation and particle attraction on non-conductive surfaces where permanent ESD flooring or matting is not practical.
Selecting the wrong product wastes budget and can leave surfaces inadequately protected. The correct choice depends on five variables:
Do not use standard household cleaners, silicone-based products, alcohol, or wax-containing solutions on ESD-controlled surfaces. These leave insulative residues that increase surface resistance and directly compromise ESD protection.
Anti-static spray is one component of a broader ESD control programme. Understanding where it fits, and where it does not, prevents over-reliance or under-specification.
| Control Method | Mechanism | Best Use Case | Limitation |
| Anti-static spray | Topical coating reduces surface resistivity | Existing non-ESD surfaces; flexible treatment | Requires reapplication; not a permanent fix |
| ESD matting | Inherently dissipative two or three layer material | Workbenches and floor mats in EPAs | Fixed installation; surface must be maintained |
| ESD flooring | Conductive or dissipative floor tiles/vinyl | Permanent EPA flooring | High installation cost; must be cleaned with ESD-approved products |
| Ionisation | Air ions neutralise charge on non-grounded surfaces | Insulators that cannot be grounded or treated | Equipment cost; maintenance of ion balance |
| Wrist straps and grounding | Ground operators directly | Personnel grounding at workbenches | Requires regular testing; ineffective if not worn |
| ESD packaging | Prevents charge generation on stored/shipped items | Component storage and transit | Consumable cost |
When anti-static spray is the right choice:
When spray alone is insufficient: Anti-static spray does not replace grounding. Surfaces must still be bonded to earth for static charge to dissipate effectively. In high-throughput PCB assembly, a comprehensive ESD programme – ESD mats, flooring, wrist straps, ionisation, and topical treatment is required to meet IEC 61340-5-1.
The primary standard governing ESD control programmes in UK and European electronics manufacturing is IEC 61340-5-1 — the international standard for the protection of electronic devices from electrostatic phenomena. It defines:
ANSI/ESD S20.20 is the equivalent US standard, widely referenced in global supply chains and required by many US-based OEM customers. Products carrying ANSI/ESD S20.20 compliance markings, such as Staticide® hand lotion, are approved for use in EPAs conforming to this standard.
Key compliance requirements that anti-static sprays support:
Audit risk: A common cause of ESD failures during compliance audits is the use of non-ESD cleaning products by facilities or contract cleaning staff. Standard commercial cleaners often contain silicone, wax, or alkaline compounds that leave insulating films on mats and floors, increasing resistance to ground and invalidating EPA status. Any cleaning contractor working within an EPA must use only approved ESD cleaning products and be trained in ESD awareness.
Anti-static sprays and ESD cleaning products should carry documented test data, including electrostatic decay time, surface resistivity after treatment, and humidity performance to support audit evidence files.
Bondline Electronics Ltd has supplied static control products to UK and international electronics manufacturers since 1986. Our range covers every surface type and application within an ESD control programme.
What it is: A ready-to-use, water-based cleaning solution formulated specifically for ESD vinyl and rubber flooring.
What it does: Removes contamination from ESD flooring surfaces including dirt, grime, and particulates without compromising the floor’s static-dissipative properties. Maintains the original resistivity of ESD flooring between formal test cycles.
Key specifications:
When to use it: Apply during routine floor maintenance in EPAs. Always sweep first with an ESD dustpan and broom before applying liquid cleaner standard dustpans and brooms generate static charge and should not be used in electrostatic protected areas.
What it is: A multi-purpose neutral cleaner designed for ESD mats, workbenches, and production area surfaces.
What it does: Removes flux residues, oily fingermarks, grease, nicotine, dirt, grime, and inorganic contaminants from ESD mats and worksurfaces. Critically, it does this without degrading the surface’s antistatic properties, maintaining original surface resistivity and extending mat service life.
Key specifications:
When to use it: Regular cleaning of ESD mats is essential. Accumulated flux and contamination create an insulating barrier on mat surfaces, preventing effective charge dissipation. Never use IPA wipes, Dettol, alcohol, or silicone-based products on ESD mats; these corrode ESD properties and will cause audit failures.
What it is: A ready-to-use topical anti-static spray for non-porous surfaces, the standard choice for electronics manufacturing environments.
What it does: Reduces a static charge to zero volts on treated surfaces. Inhibits static charge generation on carriers, tote boxes, component trays, plastics, and any non-porous surface that comes into contact with static-sensitive devices.
Key specifications:
Application methods: Trigger sprayer (8–12 inches from surface), fine-mist sprayer, foam roller, wiping, dipping, transfer roller, gravure or flexographic coating.
What it is: A ready-to-use anti-static spray formulated specifically for porous surfaces, including carpets, upholstery, and fabrics.
What it does: Eliminates static charge on porous materials that general-purpose formulations do not penetrate effectively. Prevents charge generation on carpet, fabric, and upholstered surfaces in industrial and office environments adjacent to EPAs.
Key specifications:
Application guidance: Apply so that carpet fibres absorb the anti-static solution — the surface should feel damp but not saturated. Allow to dry fully before use. For high-production applications, use fine-mist sprayers or foam rollers for even distribution.
What it is: A static-dissipative hand lotion for operators working in ESD Protected Areas.
What it does: Moisturises the skin to improve electrical contact between the operator’s skin and their ESD wrist strap. Dry skin increases skin resistance, which can prevent effective charge dissipation through the wrist strap causing test failures and potential ESD events even when a strap is worn correctly.
Key specifications:
When to use it: Apply before wrist strap testing or at the start of each shift. Operators with chronically dry skin — common in low-humidity winter environments should use hand lotion as standard practice to ensure consistent wrist strap continuity and avoid false test failures.
Anti-static spray is a targeted, cost-effective tool for controlling electrostatic charge on surfaces that are not inherently ESD-safe. It works by depositing a conductive or static-dissipative layer that lowers surface resistivity, reduces charge generation, and accelerates electrostatic decay protecting static-sensitive electronic components from ESD damage.
For UK electronics manufacturers, the correct product depends on surface type, operating humidity, application method, and compliance requirements. Bondline’s range covers every use case from general-purpose sprays for non-porous production surfaces, to heavy-duty formulations for porous flooring, to specialist mat cleaners, floor cleaners, and operator hand lotions for EPA compliance.

Anti-static spray is used to reduce electrostatic charge on surfaces, materials, and equipment in industrial and electronics manufacturing environments. It prevents ESD damage to static-sensitive electronics components, reduces dust attraction, and maintains ESD compliance in protected areas.
Staticide® topical sprays last from several weeks to several months depending on the substrate, application method, and foot or process traffic on the treated surface. Non-porous surfaces with low traffic retain the treatment longer than high-contact areas.
Staticide® formulations are proven effective below 15% relative humidity unlike many commodity anti-static products that rely entirely on ambient moisture. This makes them appropriate for use in air-conditioned, climate-controlled, or winter production environments.
The General Purpose Staticide Spray is suitable for non-porous surfaces including plastics, vinyl, metals, glass, and tote boxes. The Heavy Duty Staticide Spray is formulated for porous surfaces including carpet, upholstery, and fabric.
Yes. Staticide® General Purpose Anti-Static Spray is RoHS, REACH, CE, and IEC 61340-5-1 compliant. It meets MIL-B-81705 and NFPA-56A electrostatic decay criteria.
No. Anti-static spray reduces charge generation on treated surfaces but does not replace grounding infrastructure. Surfaces must still be bonded to earth for charge to dissipate. Spray is a complement to not a replacement for ESD mats, flooring, and grounding equipment.
