High Strength Coloured Polyurethane Floor Screed MDW-SK 20N Purcem
High Strength Coloured Polyurethane Floor Screed MDW-SK 20N Purcem
ProductDescription
It is a resin-rich, easy to trowel, heavy duty, solid color, four-component, water dispersed polyurethane-based / cement and aggregate
screed designed to provide excellent resistance to abrasion, impact, chemical attack, and other physical aggression.
It has a textured aggregate surface providing medium to heavy profile slip resistance. Typically installed at 6 to 9 mm thickness.
Uses
The floors are primarily used to protect concrete substrates but are equally effective over most steel surfaces that have been properly prepared and supported.
Typically used in food processing plants, wet & dry process areas, freezers & coolers, thermal shock areas, dairies, breweries, wineries, distilleries, laboratories, chemical process plants, pulp and paper plants, warehouses and storage areas.
Characteristics / Advantages
Easy installation requires less labor to install than traditional Sikafloor® PurCem (CN) trowel grade materials.
Resists a very wide range of organic and inorganic acids, alkalis, amines, salts, and solvents. Consult Sika Technical Sales for full details. Refer to the Sikafloor® PurCem (CN) Chemical Resistance Chart.
Similar coefficient of thermal expansion to concrete allowing movement with the substrate through normal thermal cycling. It will perform and retain its physical characteristics through a wide temperature range from -40ºC up to 120ºC.
Steam cleanable at 9 mm thickness.
Bond strength in excess of the tensile strength of concrete, concrete will fail first.
Non-taint, odorless.
Behaves plastically under impact / deforms but will not crack or debond.
Naturally textured surface through the entire life of the product.
Extra Expansion joints are not necessary; simply maintain and extend existing expansion joints up through the Sikafloor® PurCem (CN) Flooring System.
USDA acceptance for use in food plants in the U.S.A.
Canadian Food Inspection Agency acceptance for use in food plants in Canada.
