Tested according to AgBB test criteria for VOC emissions of building materials in interior rooms.The evaluations scheme of AgBB (Ausschuss zur gesundheitlichen Bewertung von Bauprodukten) /Committee for the evaluation of building materials regarding health effect) has been derived by theEnvironmental and Health Authorities for the use of building materials in sensitive areas, e.g.lounges.

Conductive, 2-component liquid epoxy resin, total solid according to "Deutsche Bauchemie".Material Base / Vehicle

30 kg packaging (base: 24 kg tin hobbock, hardener: 6 kg tin bucket)Packaging/Package Size

Gravel grey (Kieselgrau), stone grey (Steingrau).Special colours on request.

Exclusive colour design is possible according to FloorColor colour collection.

Colours

Note: Conductive carbon fibres within the product can lead to a visible adverse effect, particularlywhen using special colours.

Discolouration and chalking effects may occur with weathering and UV light exposure. Organicdyestuffs in e.g. coffee, red wine or leaves and various chemicals, e.g. disinfectants, acids, etc., maycause discolouration. Scratch marks may appear on the surface due to mechanical loads with grindingeffect (rubbing/sliding). Proper functioning of the coating will not be affected by these changes.

Keep in a cool, dry, and frost-free place.Shelf life of the original, tightly closed packaging: Minimum 2 years. If temperatures are low, thematerial should be stored at 20 °C before application.

Technical Information No. 472Application

All types of interior mineral substrates.The substrates must be sound, dimensionally stable, solid, dry, clean, and free from loose/brittle particles, dust, oils, fats/greases, rubber wear debris (skid marks) or other substances that mayprevent good adhesion.Cementitious cast mortar screed, upgraded with synthetic resin, must be checked for compatibility bytrial coatings, if necessary.The pull-off (adhesive/tensile bond) strength of substrates must be 1.5 N/mm² on an average, with aminimum individual value of 1.0 N/mm².

Substrates must have achieved their equilibrium humidity:Concrete and cement-based composition floor (screed): max. 4 % by weightAnhydrite screed: max. 0.5 % by weightMagnesite screed: 2 - 4 % by weightXylolithe (Magnesium Oxychloride) screed: 4 - 8 % by weightRising damp/moisture must be avoided. For anhydrite and magnesite screeds complete sealing fromcontact with ground is essential.

Suitable Substrates

Prepare the substrate by suitable means, e.g. ball blasting (shot peening) or milling, in order to fulfilthe above mentioned requirements. Always remove existing 1-component coatings and non-adherent2-component coatings.Clean and roughen (flatten) vitreous surfaces and surfaces of rigid 2-component coatings by sanding/grinding or blasting or prime with Disbon 481 EP-Uniprimer.Repair spallings and defects with Disbocret® PCC or Disboxid EP mortars, filling them flush with thesurface.

Substrate Preparation

Add the hardener to the base material and stir intensively with a suitable low-speed electric paddlemixer (agitator; max. 400 rpm), until a homogeneous, streak-free colour shade is achieved. Pour themixture into another clean container and continue stirring.

Preparation of Material

Base : hardener = 4 : 1 parts by weightMixing Ratio

Apply with short-pile roller, suitable squeegee (scraper/wiper, V-notched, made of metal or hardrubber), spiked roller.

Method of Application

Priming CoatPrime mineral substrates with Disboxid 462 EP-Siegel Neu (New), filling all pores. Apply the primerwith a smooth hard rubber wiper (squeegee) working in back-pull technique, then treat the surfacecrosswise by roller.Consumption*:Disboxid 462 EP-Siegel Neu (New): approx. 300 - 400 g/m²Recoat the applied priming coat within 24 hours with Disboxid 471 AS-Grund, if not being sand-treated.

Scratch-Filler (if necessary)Level rough, porous substrates after priming with an additional scratch-filler coat.Consumption*:Disboxid 462 EP-Siegel Neu (New): approx. 660 g/m² per mm of coating thicknessDisboxid 942 Mischquarz: approx. 1 kg/m² per mm of coating thickness.

Alternatively the following products can be used for priming and scratch-filler application, as perrequirement:Disboxid 420 E.MI PrimerDisboxid 460 EP-GroundDisboxid 461 EP-FillerPlease note: If Disboxid 462 EP-Siegel Neu (New) is used for priming/scratch-filler application, thenthe surface must be recoated within 24 hours. Intermediate grinding is obligatory for longer waitingtimes. For all other priming materials follow the waiting times given in the corresponding TechnicalInformation. For further details please see the corresponding Technical Information.A system coating as per AgBB test criteria is not possible, if Disboxid 460 EP-Ground and Disboxid461 EP-Filler are used.

Laying the Earthing ConnectionsAllow the priming coat to harden, then stick self-adhesive copper strips Disbon 973 (length: approx. 50cm) circulating the wall area (see figure) in a distance of max. 20 m. A minimum of two earthconnections is required. For this purpose use the contact points of Disboxid 975 Leitset (conductiveset).Surfaces that are separated by joints must be separately grounded. A maximum distance of ≤ 20 mbetween copper strips has to be respected in case of large seamless surfaces.Clean the surface of applied copper strips with a cloth, wetted with thinner Disboxid 419 Verdünner.The copper strips must always be connected by an expert for electrical supply with the earthing/grounding of the building after having finished all coating procedures.

Surface Coating System

Technical Information No. 472

Layout for Earthing Connections:

1. Disbon 973 Kupferband2. Braided wire made of copper, 4 mm² for connection to the earthing/grounding (ring line)

Conductive Intermediate CoatingRoller-apply a conductive coating of Disboxid 471 AS-Grund on the priming coat. Allow theconductive intermediate coat to harden, then, before applying the finishing coat, check for sufficientconductivity.The resistance to earth must not exceed 5 x 104 ohm. Distance between measuring electrode andground connection should be between 8 to 10 meters. Additional earthing connections must beinstalled, if the resistance is higher.Consumption*:Disboxid 471 AS-Grund: approx. 100 g/m²Disboxid 5022 WHG-Leitschicht: approx. 120 g/m²

Note: Ensure sufficient ventilation during drying and curing phases.

Top CoatingConductive flow coating (self-levelling) with Disboxid 472 AS-Deckschicht for floorspaces subjected tohigh mechanical loads.

Cast Disboxid 472 AS-Deckschicht to the floorspace and spread evenly with a notched hardrubbersqueegee (approx. 3 mm V-notching)**. Then draw with the reverse side of squeegee over the freshlyapplied coating. Leave to stand for approx. 10 minutes, after that it is essential to deaerate the surfacewith a spiked roller in order to obtain an alignment of carbon fibres.Consumption*:Disboxid 472 AS-Deckschicht: approx. 1.5 - 2 kg/m²

Note: On principle only one coat of material is applicable. This applies for all top coatings. For repairsor reworks a conductive intermediate coat of Disboxid 471 AS-Grund (including earthing) is alwaysrequired.

*Determine the exact amount of material required by coating a test area on site.**Only for recommendation. The required notching is always depending on the wear resistance oftools, temperature and substrate requirements.

Application Conditions

Technical Information No. 472

Waiting time between priming coat of Disboxid 462 EP-Siegel Neu (New) and intermediate coat: min.12 hours, max. 24 hours.Waiting time between Disboxid 471 AS-Grund and top coating: min. 16 hours, max. 2 days.Higher temperatures shorten and lower temperatures extend these waiting times.

Waiting Time

At 20 °C and 60 % relative humidity, walkable after 1 day. Completely hardened after 7 days. Lowertemperatures extend the curing time. During hardening/curing (approx. 24 hours at 20 °C), the appliedcoating has to be protected against moisture to avoid surface faults.
