LEVL Coat 351 AS — antistatic polyurethane self-levelling floor
LEVL (INGRI)

LEVL Coat 351 AS — antistatic polyurethane self-levelling floor

Polyurethane floors

LEVL Coat 351 AS antistatic polyurethane floor combines chemical resistance with combustibility group G1, confirmed by a certificate. The system is built in order: epoxy primer, copper earthing circuit, LEVL Coat 105 AS conductive layer and the 351 AS self-levelling layer, which is spread with a building squeegee; a notched trowel is prohibited here. Electrical resistance is 10⁶–10⁹ ohm, Taber abrasion up to 50 mg, elongation at break from 12 %. Conductive fibres are visible in light colours; the main sites are chemical plants, hangars, oil refining, electronics, laboratories and battery rooms.
