ESD: A SIMPLE EXPLANATION
What is electrostatic charge?
And why does your component need protection?
What is ESD?
Electrostatic discharge: the sudden release of stored electrical charge. Even a few volts can cause permanent, invisible damage to sensitive electronic components.
How does static electricity build up?
Electric charges accumulate on insulating surfaces due to friction and contact. Plastics do not dissipate this charge.
Hazards in 3D Printing
Common printing materials such as PA12, ABS, and PETG are electrical insulators. Their porous surfaces further exacerbate static charge buildup. There is no ESD protection.
ATEX and Explosion Protection
In areas containing flammable gases or dust, an ESD spark can act as an ignition source. Components used in such areas must be demonstrably conductive – this is required by law.
dichtol ESD provides dual protection: The product permanently seals pores and microstructures in 3D-printed parts while simultaneously making the surface electrostatic dissipative. This allows charges to be dissipated in a controlled manner, rather than building up uncontrollably or discharging suddenly. And all of this in a single step.
THE PROBLEM – AND THE SOLUTION
Why 3D printing without impregnation is not sufficient in ESD areas
Without treatment
- Porous – permeable to gases and liquids
- No ESD protection – dangerous for sensitive electronics
- Not suitable for use in ESD-protected zones or ATEX-regulated areas
- Multiple steps, mixing, or oven curing required
with DICHTOL ESD
- Micro-pores and hairline cracks permanently sealed
- Protection against electrostatic charge – measurable
- Suitable for ESD protection zones and potentially explosive atmospheres
- 1-component, ready to use – all in one step
Designed for components in demanding production environments
dichtol ESD combines multiple protective functions into a single system, without compromising on application or results.
HOW IT WORKS
Apply in 3 steps. Done.
1
Prepare the component
The component must be clean and free of dust, powder residue, and grease. Wear gloves and safety goggles before use.
2
Apply
Spray, brush, or roll. The surface must be kept moist in accordance with the component’s geometry.
3
Let it harden & you're done
Dries on the surface in a few minutes. Fully cures at room temperature in 24 hours.
TYPICAL APPLICATIONS
Where dichtol ESD is used
Anywhere where 3D printing intersects with electronics or ESD protection requirements.
Parts holder
For use in electronics assembly or in ESD-protected areas. Both airtight and conductive.
Electronic Enclosures & Covers
Sealed and ESD-safe for direct use near sensitive components and circuit boards.
Tools & Handling Aids
Tools that come into direct contact with ESD-sensitive components receive the necessary protection with dichtol ESD.
Mounts, Clips, Grippers & Spacers
Structural components straight from the printer. Suitable for sensitive manufacturing environments.
Component & Tool Boxes / Storage Containers
Storage containers for ESD-sensitive parts: moisture-tight and safe against static discharge.
Potentially explosive atmospheres (ATEX)
In areas with explosive atmospheres, components must be conductive – dichtol ESD meets this requirement.
MEASURABLE EVIDENCE
Protection you can measure
The ESD protection provided by dichtol ESD can be verified directly using a multimeter.
- Directly measurable
A standard multimeter shows the difference immediately. Treated side: conductive. Untreated side: no reading.
- Versatile
dichtol ESD provides ESD protection exactly where it’s needed. No expensive ESD-printed material is required.
- All geometries
Whether it’s plates, enclosures, or grids – dichtol ESD delivers consistent, reliable results across all geometries.
FREQUENTLY ASKED QUESTIONS
FAQ
Sealing with dichtol ESD is suitable for all common printing processes, such as FDM, SLS, SLA, and MJF. Plastics, metals, and ceramics can be sealed as printing materials.
The product can be applied by brushing, rolling, or spraying. The most suitable method depends on the size and number of components to be sealed, as well as the equipment available at the customer’s site. It is important that the components are treated with dichtol for 3–5 minutes before they dry. dichtol ESD must be shaken or stirred before application to ensure even distribution of the particles.
With each coat of dichtol ESD, the color becomes darker, eventually turning black.
With each layer of dichtol ESD, more conductive particles are applied, which increases conductivity and reduces surface resistance.
It is difficult to tell whether dichtol ESD is evenly distributed on black components. For this reason, a blue-colored version, dichtol ESD blue, was developed.
We recommend allowing 24 hours for drying to ensure that the sealant is completely dry, even on walls several millimeters thick. The drying process can be accelerated by raising the temperature, for example, in an oven.
