Weak or poorly bonded <br />layers e.g. release agents, old adhesive, smoothing <br />compounds and residues of floor finishes or paints must <br />be completely removed.</p> <p>Technical Data: <br />Basis: <br />two-component epoxy resin <br />Colour: transparent <br />Viscosity: <br />approx. 600 ± 80 mPA/s <br /> at +25 °C <br />Mixing ratio: <br />100:52 parts by weight <br />Mix density: <br />approx. 1.09 ± 0.02 g/cm3 <br />Pot life: <br />approx. 35 mins at +23 °C <br />Application temperature: min. approx. +10 °C, <br /> max. +35 °C <br />Traffic after: <br />min. approx. 12 hrs <br /> at +23 °C <br />Ready for overcoating: after approx. 12 hrs, <br /> up to a max. 7 days at <br /> +23° C/50% RH <br />Fully cured: <br />after approx. 7 days <br /> at +23 °C <br />Curing temperature <br />(Material / substrate): +10 °C to +30 °C <br />Tensile adhesion strength: B 1.5 (Concrete failure) <br />Water vapour <br />permeability: <br />SD > 50 m <br /> <br />(Class III according to <br /> EN 1504-2)</p> <p>ASODUR-SG3 can be used on the following substrates: <br />• on concrete and cement-based screeds subject to <br />moisture penetration from the rear <br />• concrete and cement-based screeds with increased <br />residual moisture *. Note: residual moisture of <br />cementitious substrates: dry or damp (according to <br />Def. RiLi SiB).* * “Guidelines for the protection and <br />restoration of concrete building elements” part 2, <br />paragraph 1.2.5 “Concrete moisture”. <br />“Dry”: An approximately 2 cm deep freshly prepared <br />cut-out area may not become visibly lighter as a result of <br />drying out. (In cases of doubt the concrete is considered <br />dry if it shows moisture balance for the climatic <br />conditions 23/50: i.e. dependent on concrete type <br />other absolute values are considered as “dry”). <br />“Damp”: The surface has a matt damp appearance but <br />should not exhibit a shiny film of water. The pores of <br />the substrate may not be saturated, i.e. water droplets <br />applied must be absorbed and after a short time period <br />the surface must once again appear matt.</p> <p>1/3</p> <p>49/15</p> <p>In addition the following criteria are to be fulfilled <br />dependent on the substrate: <br />Cementitious surfaces: <br />• Concrete quality: <br />min. C 20/25 <br />• Screed quality: <br />min. EN 13813 CT-C25-F4 <br />• Render quality: <br />min. P III <br />• Age: <br />min. 28 days <br />• Tensile adhesion: <br />≥ 1.5 N/mm2 <br /> <br />(render: min. 0.8 N/mm2) <br />Product preparation: <br />Components A (resin) and B (hardener) are delivered <br />at a predetermined mixing ratio. Tip component B <br />into component A. Ensure that the hardener drains <br />completely from its container. Mix both components <br />together using a suitable rotary stirrer at approx. <br />300 rpm (e.g. mixing paddle and drill). It is important <br />that stirring agitates the sides and bottom so as to <br />equally disperse the hardener. Stirring is to be continued <br />until the mix is homogenous (free from streaks): mix time <br />3 minutes. During the mixing process the temperature <br />should be approx. +15 °C. Do not use mixed material <br />directly from the packaging! Decant the mixture into a <br />clean mixing bucket and thoroughly stir through once <br />again. <br />Note: <br />When applying the product please ensure that the <br />material is evenly “flooded” over the prepared substrate. <br />Uneven areas lead to capillary pores in the hardened <br />priming coat, which benefits the formation of bubbles, <br />especially osmosis bubbles. To ensure a pore free <br />priming coat, apply the primer in two coats “wet in <br />wet”. The pore-free finish can be enhanced by the <br />application of a second coat of a watertight smoothing <br />mortar. This smoothing mortar is to be produced from <br />the priming resin with the addition of quartz sand – see <br />production: levelling/key coat. <br />When mixing aggregate (e.g. quartz sand) it must be <br />ensured that the aggregate is dry and is also at +15 °C. <br />Production of levelling/key coats: <br />ASODUR-SG3: <br />1.0 part by weight <br />Quartz sand: <br />approx. 1.0 part by weight <br /> <br />(particle size 0.1 - 0.4 mm or <br /> <br />0.2 - 0.7 mm)</p> <p>Suitable filler: <br />approx. 2 - 3 % by weight <br />The quartz sand is to be added to the previously <br />mixed and decanted resin and hardener components. <br />Ensure that the liquid and solid components are evenly <br />dispersed. <br />Method of application / consumption: <br />Primer: <br />ASODUR-SG3 is flood applied, pore-tight in one <br />application. Consumption: approx. 400 – 670 g/m2. <br />Advice: <br />• The consumption values for ASODUR-SG3 are in <br />accordance with the established water vapour <br />emission values. Method of measurement: Calcium <br />chloride test. <br />• The cleaned and primed area must be overcoated <br />within 12 hours up to a maximum of 7 days at <br />+23° C / 50% RH. <br />• Non-sanded primer may only be trafficked with clean <br />“overshoes”. <br />It is possible to broadcast a second layer of quartz sand <br />(grain size: e.g. 0.2 – 0.7 mm). <br />Consumption: approx. 0.8 – 1.0 kg/m2 <br />Once cured, thoroughly remove all non-bound quartz <br />sand before applying coatings/scratch coats. <br />Levelling/key coat: <br />Firstly prime the substrate with ASODUR-SG3 as <br />previously described. The mixed smoothing mortar is <br />applied in one application using the bonding coat <br />technique. Consumption of prepared smoothing <br />compound: approx. 1.600 g/m2/mm <br />Health & Safety: <br />Once cured ASODUR-SG3 is considered harmless. The <br />hardener (component B) is corrosive. We refer to the <br />current advice/brochures distributed by Plastics Europe, <br />www.plasticseurope.org, “Epoxy resins and hardeners”. <br />Supplementary information: <br />BGR 190 – Regulations for the use of breathing <br />apparatus <br />BGR 192 – Regulations for the use of eye and face <br />protection</p> <p>2/3</p> <p>49/15</p> <p>BGI 868 – Protective gloves for use with chemicals. <br />Observe the advice given on the packaging. <br />Important advice: <br />•H <br /> igher temperatures shorten the pot life. Lower <br />temperatures increase the pot life and setting time. <br />Material consumption is also increased at lower <br />temperatures. <br />• T he bond between coats can be impeded through <br />the influence of moisture or contamination between <br />successive coats. <br />•W <br /> hen longer waiting times occur between the <br />individual layers or where the surface already <br />prepared with synthetic liquid resin needs to be <br />renewed, the existing surface must be well cleaned <br />and abraded, after which a completely new pore-free <br />sealing is to be undertaken. <br />•S <br /> urface protection systems must be protected from <br />damp (e.g. rain, melt-water) for 4 – 6 hours after <br />application. Dampness produces a white colouration <br />and/or stickiness on the surface and leads to <br />breakdown during curing. Discoloured and/or sticky <br />surfaces must be removed, e.g. by abrasion or <br />blasting, and renewed. <br />•A <br /> pplications that are not clearly explained in this <br />technical data sheet may only be carried out after <br />consultation with and written confirmation from the <br />Technical Services Department of <br />SCHOMBURG GmbH Systembaustoffe. <br />•D <br /> ipsose of cured product residues under waste code <br />57123 “epoxy resin”.</p> <p>Information about the emission level of volatile compounds in indoor <br />air, which pose a health risk by inhalation, on a scale from class A+ <br />(very low emissions) to C (high emissions).</p> <p>Please observe a valid EU safety data sheet! <br />GISCODE: RE 1</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
