Product Description

Sikafloor®-381 ECF is a two part, electrostatic conductive self-smoothing, coloured epoxy resin with very high chemical resistance. Sikafloor®-381 ECF is the main wearing course of the Sikafloor® Multidur ES-31 ECF System, the Sikafloor® Multidur ES-31 ECF/ V System and the Sikafloor® Multidur EB-31 ECF System.

Best Uses

Sikafloor®-381 ECF may only be used by experienced professionals. Chemically highly resistant coating for concrete and screed surfaces in bund areas for the protection against water contaminating liquids (according to resistance table). Electrostatic conductive wearing layer for areas subject to chemical and mechanical exposure in production and storage facilities.

Suitable as a wearing course in industries, such as automotive, electronics and pharmaceutical manufacturing, storage facilities and warehouses. Particularly suitable for areas with sensitive electronic equipment e.g. CNC machinery, computer rooms, aircraft maintenance sheds, battery-charging rooms and areas subjected to high explosion risk.

  • Very high chemical resistance
  • High mechanical resistance
  • Impervious to liquids
  • Abrasion resistant
  • Electrostatic conductive
  • Slip resistant surface possible

Application

The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull off strength of 1.5 N/mm². The substrate
must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. If in doubt apply a test area first.
Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured
surface. Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, SikaDur® and SikaGard® range of materials. The concrete or screed substrate has to be primed or levelled in order to achieve an even surface. High spots must be removed by e.g. grinding. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.

MIXING
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 minutes until a uniform mix has been achieved. When parts A and B have been mixed, add the quartz sand 0.1 - 0.3 mm and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment. Sikafloor ®-381 ECF must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.

APPLICATION
Wearing course (horizontal areas): Sikafloor®-381 ECF is poured, spread evenly by means of a serrated trowel e.g. Large-Surface Scraper No. 656, Toothed blades No. 25. After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish. Roll immediately (within max. 10 minutes of application) in two directions with a steel spiked roller to ensure even thickness and to remove entrapped air. To obtain the
highest level of aesthetic finish, spike roll in two directions at a 90 degree angle, passing only once in each direction.

Wearing course (vertical areas): The first layer of Sikafloor®-381 ECF, mixed with 2.5 - 4 wt.-% Sika Extender T, has to be applied by trowel. After placing of the earthing plates and application of the conductivity layer, apply the second layer of Sikafloor®-381 ECF, mixed with 2.5 - 4 wt.-% Extender T, by trowel.

Wearing course with slip resistance: Sikafloor®-381 ECF is poured, spread evenly by means of a serrated trowel and the fresh layer is broadcasted to excess with silicon carbide 0.5 - 1.0 mm. After final drying the surplus silicon carbide must be swept off and the surface must be vacuumed.
