Conductive chemical-resistant polyurethane–cement flooring LINCRETE® AS ECF (3–6 mm)

Lincrete® AS ECF (3–6) is a chemically resistant conductive polyurethane–cement flooring system for protecting concrete substrates (floors) in food, pharmaceutical, chemical and petrochemical production facilities.

Lincrete® AS ECF (3–6) is a modified self-leveling four-component polyurethane–cement system that provides a durable floor:

• conductive, with electrical resistance low enough to ensure rapid charge dissipation in the presence of grounding or connection to a lower potential point;
• meeting sanitary and epidemiological requirements;
• having a long service life;
• resistant to chemical exposure, blood and fats, lactic acids, oils and fuels and lubricants;
• resistant to commonly used disinfectants and cleaning agents.

Key material features:

Fast and simple application

Lincrete® AS ECF (3–6) flooring is suitable not only in terms of conductive, chemical and mechanical performance for food, chemical, petrochemical and pharmaceutical facilities, but also in terms of installation conditions. The mixed material is poured onto the substrate and spread with a notched trowel with pin spacers. Immediately after spreading, the surface must be treated with a spike roller. Spiked shoes must be used to move over the fresh material. There is no need to completely stop production on an operating site or in a production area, since the coating gains strength quickly and the floor can be walked on after 12 hours at 20°C. Full pedestrian loading is recommended after 24 hours, and traffic loading after 72 hours.

Resistant to high temperatures

The coating does not suffer damage either in service or during steam cleaning under extreme temperature conditions. The material can be applied at different thicknesses — 3 or 6 mm, depending on the expected loads:

• at 3 mm thickness the coating is not damaged in service or during cleaning at temperatures from −25°C to +80°C;
• at 6 mm thickness the coating is resistant to temperatures from −35°C to +90°C.

Chemical resistance

Chemical resistance table for Lincrete® AS ECF (3–6) according to DIN EN 13529 (95/1999). The table shows resistance after 1 day of continuous exposure of the spilled substance on the specimen surface.

Chemical spills must be removed as quickly as possible and the flooring surface cleaned. The longer the exposure, the more severe the damage to the coating. The substances were tested at room temperature; higher operating temperatures can accelerate coating degradation under spills. Changes in color and gloss generally do not indicate a loss of mechanical strength.
