SXNOTTO Siloxan 290LThe siliconesurface impregnationCharacteristics:• Ready-to-use silicone surfaceimpregnation• High penetration depth• UV-resistant• Can also be applied on moistsubstrates (not rain-wet)• Forms a water- and dirtrepellingsurface• The hydrophobe effect prevents the penetration of moisturefrom the outside to the inside but it lets the internalmoisture escape to the outside• Bridges hair cracks up to a width of 0,3 mm• Reduces the tendency of treated surfaces to pick up dirt• Avoids humidity in the construction material thus avoidssalt efflorescence as well as moss and algae growth• Paintable with commercial dispersion paints• Odourless• Colourless• Slight deepening of colour is possibleFields of application:• Hydrophobic treatment of façades and building componentsmade of concrete, cellular concrete, fibre cement,brick-work, natural and artificial stone, mineralic plastersand coatings• Drainage of moist and cracked surfaces, which are thenpainted using dispersion paints• Only for vertical surfacesAdditional useful information:Hydrophobizing of façades results in greatly reducedwater absorption, good UV-resistance and very goodwater-repellent effect.The ready-to-use solution can be applied directly byspraying or painting it on. The substrate should be fairlydry for this treatment.Adjacent structural elements such as windows, doors,gutters etc. must be covered.Apply in two layers from top to bottom wet-on-wet. Thehydrophobed façade is resistant to rain after approximately24 hours.The differences in water absorbency are significant:Water absorbencyuntreated(approx. averagevalues dependingon material quality)Water absorbencyhydrophobed withOTTO Siloxan 290L(approx. averagevalues dependingon material quality)Concrete 3 % 0,8 %Sandstone 5 % 0,2 %Lime sandstone 13 % 0,8 %Limestone 12 % 1,1 %Clinker brick 3 % 0,1 %Brick 18 % 0,1 %Tufa 18 % 1,1 %Mortar 7 % 1,2 %Colour5 lCanister10 lCanister25 lCanistercolourless SXN-58 SXN-60 SXN-62Packaging unit 1 1 1Pieces per pallet 82 50 24110Other quantities on request.
