WANSHIELD®62103 Anti – static Water – based Epoxy Primer for Floor Coating
WANSHIELD® 62103 Antistatic Water-Based Epoxy Primer is a two-component, water-based epoxy resin adhesive with reactive curing properties. As an environmentally friendly coating, it serves as a conductive black primer for antistatic epoxy flooring and can be combined with quartz sand or other fillers to formulate conductive epoxy mortar intermediate coatings.
Product Overview
WANSHIELD® 62103 Antistatic Water-Based Epoxy Primer is a two-component, water-based epoxy resin adhesive with reactive curing properties. As an environmentally friendly coating, it serves as a conductive black primer for antistatic epoxy flooring and can be combined with quartz sand or other fillers to formulate conductive epoxy mortar intermediate coatings.

Surface Preparation
Substrate Requirements
- For Concrete Floors: Minimum compressive strength ≥ C25; pull-off strength ≥ 1.5 MPa.
- Remove all contaminants (oil, grease, loose particles, old coatings) to expose sound concrete.
- Grind the surface to achieve a profile of CSP3-6 using shot blasting or mechanical abrasion.
- Ensure flatness ≤ 3mm (checked via 2m straightedge). Repair low areas with epoxy mortar.
- Substrate moisture content must be <6%; curing period completed.
Application Conditions
- Ambient Temperature: 10–35°C.
- Substrate Temperature: ≥3°C above dew point.
- Humidity: <85% RH.
- Pot Life: 50–60 minutes (23°C).
- Ventilation: Dust-free environment; avoid strong airflow.
Application Guidelines
| Parameter | Specification |
| Mixing Ratio (A:B) | 3:1 by weight; mix thoroughly. |
| Water Dilution | Max. 35% of Component A weight. |
| Pot Life (at 23°C) | 50 minutes. The higher the temperature, the shorter the pot life. When the ambient temperature during construction is higher than 40°C, construction is generally not recommended. |
| Application Methods | Roller, brush. |
| Cleaner | Water. |
| Drying Time | Surface dry: 8h; Full cure: 48h (23°C, 60% RH). |
| Recoat Interval | ≥24h (ensure full curing before overcoating). |
Note: Drying times vary with temperature, humidity, film thickness, and ventilation. Test under job-site conditions prior to full-scale application.
Packaging & Storage
Safety Precautions
PPE Requirements:
NIOSH-approved respirator
Chemical goggles + nitrile gloves
First Aid:
Skin: Soap/water → seek medical help if irritation persists.
Eyes: 15-min flush → immediate ophthalmologist visit.
Fire Rating:
This product is not classified as a flammable liquid, explosive, oxidizer, corrosive, toxicant, or radioactive hazardous material during storage and transportation, and is not a hazardous product.
NFPA 704: 0-1-0
Extinguishing: CO₂/dry chemical
- In the absence of other fire-fighting agents, a large amount of fog-like water can also be used for spraying. After the fire is extinguished, the spilled materials should be cleaned up (refer to the leakage and spillage treatment section).
