DUROFLOOR-C is a two-component, solvent-free, colored epoxy system offering permanent conductivity that prevents the appearance of static electricity charges on surfaces. It has a conductivity resistance between 10 4 and 10 6Ohm*. DUROFLOOR-C has high strength and abrasion resistance, it is resistant to organic and inorganic acids, alkalis, petroleum products, a number of solvents, waste, water, sea water and weather conditions.
Certified according to EN 13813 and classified as SR-B2.0-AR0.5-IR4. CE marked.
DUROFLOOR-C is used as a self-leveling floor coating on cementitious floors to eliminate the risk of spark generation caused by static electricity. Suitable for computer rooms, laboratories, printing rooms, textile mills, gas stations, electrical stations, ammunition storerooms, etc.
Substrate
The flooring surface should be:
- Dry and stable.
- Free of materials that might impair bonding, e.g. dust, loose particles, grease, etc.
- Protected from underneath moisture attack.
Depending on the nature of the substrate, it should be prepared by brushing, grinding, sandblasting, water blasting, shot blasting, etc. Following this, the surface should be cleaned from dust with a high suction vacuum cleaner.
Priming
The surface is primed with DUROFLOOR-PSF or DUROPRIMER epoxy primers.
Consumption: 200-300 g/m2. After the primer has dried, any existing imperfections (cracks, holes) should be filled using DUROFLOOR-PSF mixed with quartz sand, with a particle size of 0-0.4 mm (or Q35), in proportions of 1:2 up to 1:3 by weight. The application of the conductive floor should take place within 24 hours after priming. If the conductive floor is to be applied 24 hours after priming, quartz sand with a particle size of 0.3-0.8 mm should be spread on the surface, while the primer is still fresh, in order to ensure good bonding. After hardening of DUROFLOOR-PSF, any loose grains should be removed using a high-suction vacuum cleaner.
Wet substrate
If the product is to be applied to a substrate with a moisture content of >4% or to a fresh concrete floor (3-28 days), the surface should be primed with the water-based 3-component primer DUROPRIMER-W.
Conductive layer
After drying of the primer, the special self-adhesive copper tapes (conductors) should be installed on the floor in a grid formation of approximately 5 m x 5 m and connected to the ground through a perimeter cable.
Afterwards, the surface is coated with DUROFLOOR-CV conductive epoxy varnish, applied with a roller in a thin layer.
Consumption: approx. 200 g/m2/
DUROFLOOR-C should be applied within the following 24 hours after DUROFLOOR-CV application, but after it has dried.
Application of self-leveling DUROFLOOR-C
a) Mixing of the components
Components A (resin) and B (hardener) are packaged in two separate containers, at the correct predetermined mixing ratio by weight. Before mixing, component A is stirred mechanically for 1 min. Then, all of component B is added to component A and two components are mixed continuously for about 5 min with a low-speed mixer (300 rpm) until a uniform mix is obtained. It is important to thoroughly stir the mixture near the sides and bottom of the container to achieve uniform dispersion of the hardener. To ensure thorough mixing, the mixture is poured into a clean container and mixed again for at least 1 min until fully homogeneous.
b) Application – Consumption
DUROFLOOR-C is spread (dragged) on the floor using a smooth trowel, to a thickness of approx. 1.5 mm.
Consumption: approx. 1.5 kg/m2/mm.
