System capable of dissipating electrostatic charges and preventing harmful discharges (ESD).
Colored self-leveling system for cementitious substrates free from rising damp, capable of dissipating electrostatic charges.
The system is based on epoxy resins with high-solid formulations, providing a thickness of 2.5–3 mm.
The products are treated with highly conductive additives to produce antistatic flooring, ensuring electrical conductivity sufficient to prevent the accumulation of electrostatic charges.
Typical applications of antistatic coatings include the chemical, electronics, and mechanical industries (particularly in areas with AGV trolleys), operating rooms, and environments where flammable or explosive atmospheres may be present.
Substrate Preparation
Concrete substrates must be solid, dry, leveled, absorbent, and free from oils, detergents, dust, or other contaminants.
For newly cast screeds, allow the normal curing time. Assess the most suitable mechanical preparation method: grinding or shot blasting.
As this is a non-breathable system, check for the presence of a vapor barrier, and ensure that there is no rising damp (otherwise, use the AUT07 system). Additionally, provide grounding of the concrete to ensure a resistance between 10,000 and 100,000 Ohms.
Application
- To saturate the substrate porosity, apply a coat of PAVIWATER T68 with a roller, diluted 1:3 with water, at a consumption of approximately 0.05 kg/m². Install grounding points by applying copper strips near the electrical boxes. On the same day, level with a smooth trowel using SUPERCONDUPLAST, loaded 30% with Quarzo B0, at a consumption of 0.40 kg/m².
- If necessary, fill expansion joints with SUPERCONDUPLAST, loaded 1:3 with Quarzo B1 (product consumption is negligible).
Pour the self-leveling mortar CONDUPLAST, loaded 1:0.7 with Quarzo B0, at a consumption of 2.0 kg/m². While still fresh, roll repeatedly with a spiked roller. - Apply PAVIWATER ESD with a roller, diluted 10% with water, at a consumption of 0.10–0.12 kg/m².
- Cut the coating along the concrete joints and seal with SIGILFLEX polyurethane elastomer.
The resulting coating thickness is approximately 2.5–3 mm.
