Sikafloor 21 PurCem

Sikafloor 21 PurCem is a multi-component, medium to high strength coloured polyurethane modified, cement and aggregate screed with self-smoothing properties. It has an aesthetic, easy to clean, smooth textured aggregate surface providing medium slip resistance and is typically installed at 4.5 to 6mm thick.

Uses:  In areas of medium to heavy loading, abrasion and high chemical exposure, to provide a smooth, flat wearing surface, in process areas such as:

• Food processing plants, in wet or dry process areas, freezers and coolers, thermal shock areas
• Chemical plants
• Laboratories
• Workshops
• Suitable for concrete protection providing physical resistance (Principle 5, method 5.1 of EN 1504-9)
• Suitable for concrete protection providing chemical resistance (Principle 6, method 6.1 of EN 1504-9)

Features and Benefits:

• Excellent chemical resistance.  Resists a wide range of organic and inorganic acids, alkalis, amines, salts and solvents. Please refer to the Chemical Resistance Chart or consult the Technical Department.
• 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 -40°C (-40°F) up to +90°C (194°F)
• Bond strength in excess of the tensile strength of concrete.  Concrete will fail first
• Non taint, odourless
• VOC free
• High mechanical resistance.
• High abrasion resistance resulting from its silica aggregate structure
• It is possible to apply on to 7 to 10 day old concrete after adequate preparation and with a tensile bond strength in excess of 1.5 MPa (218 psi)
• Seamless, no additional expansion joints are necessary; simply maintain and extend existing expansion joints up through the Sikafloor PurCem flooring system
• Easily maintained
• Wide range of application temperatures +10°C - +40°C
