Anti static and non sparking epoxy flooring

Details

Thickness

3.0mm 5.0mm

Surface Finish

Self-leveling trowel finish, roller coating type, glossy type

Service Life

3.0mm: 5～8 years, 5.0mm: More than 15 years

Floor Characteristics

Prevent sparks caused by static electricity collision with the ground.

Scope of Application

Production workshops and warehouses using Class A hazardous chemicals, flammable goods warehouses, and ammunition depots.

Construction Process

①Waterproofing Treatment

Waterproofing construction shall be completed for the ground floor.

②Base Surface Treatment

Repair, grind and remove dust according to the actual condition of the substrate.

③Anti-static Primer

Roll-coat 1 to 2 coats of high-permeability and high-adhesion anti-static epoxy primer to enhance surface adhesion.

④Copper Foil Laying

Lay conductive copper foil in a grid pattern to effectively release accumulated static electricity and complete grounding treatment.

⑤Anti-static Spark-free Intermediate Coat

Apply several even coats of anti-static spark-free intermediate coating with a trowel.

⑥Anti-static Putty

Apply two coats of anti-static putty until the surface is flat and pore-free, without trowel marks and sanding marks.

⑦Anti-static Spark-free Topcoat

Trowel one coat of anti-static spark-free self-leveling topcoat or roll-coat two coats. Its volume/surface resistivity ranges from 1×10⁶-1×10⁹Ω. The finished floor features a bright, clean and uniform color.

⑧Completion of Construction

Pedestrian access is allowed after 24 hours; heavy load access is permitted after 72 hours. (Based on 25℃ standard temperature; the access time shall be appropriately extended at low temperature. Keep the floor free of water during the curing period.)
