Elakor-PU Grunt Eko — food-grade polyurethane primer for food contact

Floor primers

The Eko line primer allows direct contact with food products and drinking water, so it is used in drinking water tanks, storage facilities for grain, flour, sugar and soya, malt houses, silos and swimming pools. 1–2 coats are applied under polyurethane coatings, 2–3 coats as a stand-alone protective impregnation; substrates are concrete, terrazzo, tile, stone, brick and wood. Work is permitted from −30 to +25 °C, adhesion to concrete is 6.2 MPa, fire hazard class KM1.
