Temafloor 4000 ESD |
 |
|
| DESCRIPTION | Solvent free Temafloor 4000 ESD grinding screed is prepared by adding conductive sand mixture to Temafloor 401 epoxy varnish mixture. | |
| PRODUCT FEATURES |
Forms electrically conductive coating when used with Temafloor 310 ESD
primer. Meets the requirements for conductive floor coatings according to IEC-EN 61340-5-1. High impact and good chemical resistance. |
|
| RECOMMENDED USES | Prevents electrostatic discharge damages and recommended in places where electric discharge is not desirable e.g. in electronic industry, production and storing of explosive materials, place with higher risks of ignition. | |
| TECHNICAL DATA | ||
| Features | Withstands heavy wear. Resistance to chemicals is given case by case. Withstands +110ºC dry heat and +60ºC in immersion. Non-slip. | |
| Colour Range | The colour of the screed is determined by the sand used. | |
| Gloss groups | Full-gloss | |
| Coverage | For a flat substrate:
3mm layer: 3 litres ready for use screed / m2 4mm layer: 4 litres ready for use screed / m2 Practical coverage depends on the evenness of the substrate. |

| APPLICATION DETAILS | ||
| Application conditions | The relative humidity of the concrete should not exceed 97%. The temperature of the ambient air, surface or coating should not fall below +15ºC during either application or drying. Relative humidity of air should not exceed 80%. | |
| Preparation | New concrete
Remove laitance by power grinding, vacuum grit blasting or hydrochloric acid etching. Choose the method best suited for the premises. After grinding remove dust carefully with a vacuum cleaner. Hydrochloric acid etching is carried out with diluted hydrochloric acid (1 part concentrated hydrochloric acid, 4 parts water). Rinse with plenty of water. Dry the floor. Old concrete Remove all grease, oil, chemicals and other impurities by MAALIPESU detergent. Remove old peeling paint layer by grinding, milling or vacuum grit blasting. Choose the method best suited for the premises. Clean out pot-holes removing all loose friable material. Open cracks with e.g. an abrasive tool. Remove loose material and dust. |
|
| Priming | Prime using Temafloor 310 ESD primer thinned 20-30% with Thinner 1029 according to the product data sheet. Scatter conductive sand on the fresh primer coat to ensure the screed adhesion and prevent gliding of the screed. | |
| Diluting | Do not thin Temafloor 4000 ESD grinding screed. | |
| Screeding | Pour the screed mixture onto the floor. If a thin layer is required, apply by an adjustable trowel to the desired screed thickness. Thick layers are applied by a screed box or by a straight-edge and suitable laths to gauge the required thickness. Knead the screeded surface by hands or use a suitable lightweight floating machine. | |
| Overcoating | Overcoating can be carried out after 16-24 hours using Temafloor 401 epoxy varnish thinned 20-30% with Thinner 1029. If the surface is not overcoated within 24 hrs, it should be abraded. Pour the varnish mixture onto the floor, spread with a rubber trowel and level with a roller. | |
| Mixing of components | Mix the correct proportions of base and hardener thoroughly (approx. 2 minutes) by using a hand drill with a paddle, concrete mixer or power mixer. Add conductive sand mixture to the varnish mixture by mixing carefully at the same time. Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface, weaken the properties of the screed and risk the success of the application. | |
| Cleaning of tools | Thinner 1029. | |
| EU VOC 2004/42/EC-limit value | VOC 2004/42/EC (cat A/j) 500 g/l (2010)
Temafloor 4000 ESD: max. VOC < 500 g/l |
