Field of Application

Due to the emission-minimised, ecologically compatible formula, particulary suitable for all "sensitive/delicate" areas, as e.g. lounges, hospitals, nurseries, play schools, schools, etc.
Suitable as a transparent impregnating agent on mineral floor spaces. Suitable as a primer before applying water-thinnable epoxy floor coatings.

Material Properties

  • Allows water vapour diffusion
  • Suitable for matt-moist, cement-based surfaces
  • Good chemical resistance
  • Emissin-minimised, technically controlled and supervised (TÜV)
  • General Building Approval by the German Institute for Structural Engineering
Tested according to the AgBB testing criteria for VOC emissions from building materials used in interior areas. The criteria of the AgBB (Ausschuss zur gesundheitlichen Bewertung von Bauprodukten; Commission for the sanitary evaluation of building material) are elaborated by the ecological and sanitary authorities for the use of building material in »delicate/sensitive« areas, as e.g. lounges.

Material Base / Vehicle

Water-thinnable, 2-component liquid epoxy resin.

Packaging/Package Size

10 kg plastic combi-packaging 
5 kg plastic combi-packaging

Colours

Transparent. 

Discolouration and chalking effect may occur with weathering and UV light exposure. The pigmentation in, e.g. coffee, red wine or leaves (organic dyestuffs) and various chemicals (e.g. disinfectants, acids, etc.) may cause discolouration. The efficiency of the coating will not be affected by these changes.

Gloss Level

Glossy

Storage

Store cool, dry, frost-free.
Tightly closed original packaging has a minimum shelf life of 1 year. If stored at low temperatures, the material should be stored at 20 °C before application.

Density

approx. 1.0 g/cm3

Dry film thickness

approx. 30 µm/100 g/m2

Resistance-count for diffusion µ (H2O)

approx. 38,000

Suitable Substrates

All types of mineral substrates, e.g. concrete, cement-, anhydrite- and magnesite-screeds. The substrates must be sound, dry, dimensionally stable, and free from all materials that may prevent good adhesion, e.g. release agents, dust, oil or abraded rubber contamination (skid-marks). 
Check cementitious levelling mortars, ameliorated with synthetic resins, for suitability and apply a trial coating, if necessary. If Disbopox 443 EP Impregnating Agent is used as primer for subsequent coatings, the following requirements additionally apply. 
The average adhesion tensile strength of surfaces must be 1.5 N/mm2 with a single minimum value of 1.0 N/mm2. Freshly applied concrete or cement-based composition floors / screed must be dried to a matt surface aspect (without forming a glossy film). 
Other substrates should have achieved their equivalent humidity: 
Anhydrite screed: max. 1% by weight 
Magnesite screed: 2–4 % by weight 
Magnesium oxychloride screed: (Xylolite) 4–8 % by weight

Substrate Preparation

Prepare the substrate by suitable means, e.g. shot peening, milling or grinding, fulfilling all requirements. Repair spallings and defects with Disbocret® PCC mortars or Disboxid EP mortars, flush with the surface.

Preparation of Material

Add the hardener to the base material and stir intensively with a low-speed electrical paddle (agitator / max. 400 rpm). Pour the mixture into another clean container. Add the required quantity of tap water (max. 5% by weight) for thinning, if necessary, and continue stirring.

Mixing Ratio

Base material: Hardener = 4 : 1 parts by wt.

Method of Application

The material can be applied with a sealer brush, short-fibre roller or airless spraying equipment. Stir the material occasionally during application.

Surface Coating System

Thin with max. 5 % by weight of tap (potable) water for impregnating / sealing mineral substrates, depending on the absorbency and desired layer thickness. Suitable spraying equipment: Airless unit (nozzle size 0.08").


Priming absorbent, mineral substrates before applying water-thinnable coatings
Apply the material intensively by sealer brush in one uniform coat.

Impregnating/sealing absorbent, mineral substrates
Apply one or two coats. The first coat should be applied with a sealer brush and the second coat preferably using a short-fibre roller or spraying unit.

Consumption

For absorbent substrates approx. 200 g/m2 of diluted or undiluted material per application.
The exact rate of consumption is best established by a trial coating on site.

Workability

Workability At 20 °C and 60% relative humidity, approx. 60 minutes.
Higher temperatures shorten and lower temperatures extend the potlife. 
Note: The end of potlife is not recognisable.

Application Conditions

Material, atmospheric, and substrate temperature
must remain at a min. of 12 °C and max. of 30 °C during application and drying. Relative humidity must not exceed 80%. Substrate temperature always should be min. 3 °C above the dew point temperature.

Waiting Time

The waiting time between coats varies from min. 16 to max. 24 hours at 20 °C, the same for following coats of pigmented materials with proper diffusion. If the waiting time lasts more, the surface must be roughened. Higher temperatures shorten and lower temperatures extend the given period.

Drying/Drying Time

At 20 °C and 60% relative humidity, walkable after approx. 1 day. Ready for mechanical stress (loads) after approx. 3 days and completely hardened after approx. 7 days. 
At lower temperatures the drying time is correspondingly longer. Protect the coating from moisture during the curing process (approx. 24 hours at 20 °C), otherwise surface failures and diminished adhesion may occur.

Tool Cleaning

Immediately after use or during longer breaks with water or warm soapy water.

CE Labelling

EN 13813
CE labelling is based on EN 13813 "Screed mortars, screed compounds and screeds – screed mortars and screed compounds – Properties and Requirements" defining the requirements for screed mortars being used for floor constructions in the interiors. The standard also include synthetic resin coatings and sealing.
Products matching the above mentioned standards are to be labelled with the CE mark. Additional engineer standards are effective for the use in Germany in structural safety relevant areas. Conformity is documented by the Ü sign (Überwachung = supervision) on the container. Established by documented evidence of conformity 2+ with controls and tests on the part of the manufacturer and notified bodys.
