Self-leveling chemical-resistant polyurethane–cement flooring LINCRETE® SL (4–6 mm)

Lincrete® SL is a chemically resistant self-leveling polyurethane–cement flooring system, applied at 4–6 mm thickness, for protecting concrete substrates (floors) in food, pharmaceutical and chemical production facilities. It is particularly effective in:

• slaughter and meat-processing areas;
• dairy and brewery production and bottling areas;
• alcoholic and non-alcoholic beverage production facilities;
• flour-milling plants.

In specific cases, the system is also suitable for chemical and pharmaceutical industry applications.

Lincrete® SL is a modified self-leveling four-component polyurethane–cement system that provides a durable floor:

• that meets sanitary and epidemiological requirements;
• with a long service life;
• with high resistance to chemicals, blood and fats, lactic acids, oils and fuels and lubricants;
• with resistance to commonly used disinfectants and cleaning agents.

Key material features:

Fast and simple application

Lincrete® SL flooring is suitable not only in terms of chemical and mechanical performance for food, chemical 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 — 4 or 6 mm, depending on the expected loads:

• at 4 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.

Odorless

Electrically non-conductive and non-combustible

High resistance to abrasive wear

Chemical resistance

Chemical resistance table for Lincrete® SL 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.

A — material is resistant; a small decrease in hardness (5–10 Shore units) is possible.

B — material is conditionally resistant; under longer exposure, surface damage and a decrease in hardness (10–20 Shore units) are possible.

C — material is not resistant; a significant decrease in hardness (20–40 Shore units) is observed, and the surface is damaged with blisters and bubbles.

D — possible change in gloss and color without deterioration of mechanical properties.

Spills of chemicals 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.
