Typical areas of use include engineering plants, chemical plants, traffic aisles and food processing areas. It may be sealed with Durafloor N (Novolac) in areas of significant risk from chemical attack (see separate Technical Data Sheet). Advantages „ Suitable for application in food preparation areas „ Durable - provides long-term protection in heavy industrial environments „ Improves efficiency - seamless surface aids traffic flow and cleaning „ Good resistance to a wide range of industrial chemicals „ Tough - resists high impact and point loading Description Durafloor TF Binder is a two-part low viscosity epoxy resin system to which Durafloor TF Fillers and a Durafloor colour pack can be added to produce the trowellable epoxy mortar (Durafloor TF) for the installation of a high performance industrial floor system. Durafloor TF when laid, produces a matt, slightly textured anti-slip floor system. Durafloor TF can be overcoated to provide different non-slip and sealed properties. The product can also be produced in a range of standard colours. Technical Support Parchem offers a comprehensive range of high performance, high quality flooring, jointing and repair products for both new and existing floor surfaces. In addition, the company offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance. Properties The values given below are average figures achieved for Durafloor TF in laboratory tests at 23°C. Actual values obtained on-site may show minor variations from those quoted. Physical properties Compressive strength (BS 6319): March 2013 Page 1 50 MPa Flexural strength (BS 6319): 17 MPa Cure time: Foot traffic: 24 hours Vehicular traffic: 48 hours Chemical: 7 days Pot life: 30 minutes Chemical properties Durafloor TF has excellent resistance at ambient temperature to a wide range of industrial chemicals. Note that it is especially important that spillage is cleared up since very much higher concentrations of chemicals may occur on evaporation. Maintenance The service life of a floor can be considerably extended by good housekeeping. Regular cleaning of Durafloor TF may be carried out using a rotary scrubbing machine with a water miscible cleaning agent or by hot water washing at temperatures up to 60°C. Application Instructions Durafloor TF should be installed by specialist applicators who must follow the application instructions. The following steps are involved in the application which would normally take place over a 3 - 5 day period. Preparation Correct surface preparation is essential to achieving bond between the substrate and the new floor. All concrete should be sound, clean, dry and free from contaminants. Hydro blasting, captive shot blasting or grit blasting equipment is necessary to ensure that adequate substrate preparation is achieved. On small areas, needle gunning or bush hammering is acceptable. The parent concrete should have a minimum compressive strength of 25 MPa and be free of any weak surface laitance. Priming All substrates on completion of the preparation are to be primed with Durafloor TF Binder or Nitomortar 903. More than one coating may be required depending on the porosity of the substrate. For where high build applications are required on vertical systems seeding the wet primer with a suitable grit will prevent the screed coat from sliding. March 2013
