The Technology Beyond the Coating
Filler-free ESD coating is the next step in static control. Most conventional ESD paints and plastics rely on carbon black or metal powders. These fillers create short-term conductivity but also cause long-term problems. They can segregate, drift, or wear away, leaving surfaces inconsistent and unreliable.
ProShield is different. Its conductivity comes from a pure polymer backbone, not from particles suspended in a binder. As a result, ProShield delivers permanent, homogeneous static control that filler-based paints and molded plastics cannot match.
Why Filler-Based Paints Fall Short Compared to Filler-Free ESD Coating
Traditional ESD paints are usually epoxies or urethanes loaded with conductive powders, often carbon black or metal fillers, as described by EPA guidelines on conductive coatings. At first, they seem effective, but the drawbacks appear quickly:
-
Fillers clump or settle during mixing and application.
-
Conductivity varies across the coated surface, creating weak spots.
-
Resistance values drift over time, especially in low humidity.
-
Coatings often require frequent reapplications or repairs.
-
Long-term maintenance adds cost and downtime.
Therefore, manufacturers using filler-based ESD paints often face hidden costs and inconsistent protection.
Molded Plastics vs Filler-Free ESD Coating
Molded plastics with conductive fillers are another common static-control option. They are used in trays, fixtures, and housings. However, they also present clear limitations:
-
They rely on carbon or metal powders mixed into the resin.
-
Only items that can be molded benefit from conductivity.
-
Material costs are higher than standard plastics.
-
Conductivity changes after machining, wear, or extended use.
-
Existing assets such as tables, floors, and packaging cannot be retrofitted.
In short, conductive molded plastics solve specific problems but create barriers in flexibility and cost.
The ProShield Advantage: A True Filler-Free ESD Coating
ProShield ESD coating removes these compromises:
- Filler-free conductivity – A 100% conductive polymer matrix eliminates clumping, segregation, and drift.
- Stable performance –Even in extreme low humidity conditions where many coatings fail, ProShield maintains conductivity, unlike many conventional antistatic paints.
- Multi-chemistry flexibility – Available as PU, epoxy, water-based, or solvent-based coatings. Each chemistry suits a different substrate while keeping identical conductivity.
- Universal retrofit – Floors, walls, plastics, metals, wood, cartons, and foams can all be protected. In other words, if you can paint it, you can protect it.
- Cost-effective scalability – Instead of buying expensive conductive plastics or specialist ESD furniture, ProShield retrofits existing assets, reducing total cost of ownership.
For example, an epoxy floor coated with ProShield maintains consistent conductivity year after year, while traditional carbon-filled paints often fail within two years.
Why it Matters
Choosing the right static-control technology is critical. With ProShield, industries gain protection that is:
-
More reliable than filler-based coatings, which drift and degrade.
-
More flexible than molded plastics, which are limited in form and cost.
-
More economical than replacing equipment with ESD-rated versions.
As a result, static-safe environments become accessible to small and mid-sized manufacturers, not just global corporations. ProShield lowers the barrier to compliance, making permanent ESD control practical across more industries.
