Protectosil® SC 1000
Fluorine containing formulation based on silane chemistry for an easy-to-clean treatment of porous, mineral surfaces.
Scope of Application
Protectosil® SC 1000 treated porous, mineral substrates show excellent water and oil repellency treated surfaces remain clean for longer times and are more easy to clean (common liquids like coffee, coke, oils and dark liquids are easily removed) weakens the adhesion of chewing gum or posters to e.g. facades slows down the growth of microorganisms such as mold and algae helps avoid unsightly dark water streaks is highly reactive and resistant against alkali generates watervaporpermeable, colorless impregnation no formation of sticky silicone films is suited for the treatment of water repellent substrates Protectosil® SC 1000 is suited for an easy-to-clean treatment of many mineral substrates. Protectosil® SC 1000 may be used undiluted or may be diluted using alcohols (such as ethanol or isopropanol) or xylol. The exact amount to be applied, suitable dilution rate and mode of application is highly depending on the porosity of the subsrate and should be determined on a small test patch. The facade to be treated must be clean and the surface dry. Dirt, grime, efflorescence, algae and moss must be removed. High pressure or water vapour cleaning is suitable. Water absorbed during cleaning must be allowed to dry so that the surface is dry before application begins. Imperfections such as cracks, cracked joints or defective seams must be repaired using appropriate methods. Mortar used for repairs must be fully cured and surface dry. The application is recommended if air and substrate temperatures are between 5 °C and 40 °C. Protectosil® SC 1000 should not be applied during rain or strong wind. In the case that a water repellent agent such as Protectosil® BHN or a corrosion inhibitor such as Protectosil® CIT have been applied the substrate has to set for at least 5 days before Protectosil® SC 1000 is applied. The recommended application method for Protectosil® SC 1000 is with HVLP (High Volume Low Pressure) equipment. Product application using airless sprayers (low pressure, so-called “flooding” method) is also possible if the substrate is sufficiently absorbent. The ready-to-use solution is best applied starting from the bottom and going up the wall. This avoids pre-treating the substrate with run-off from above. Avoid using dirty application equipment, which can contaminate the product. In most cases the hydro- and oleophobic effect develops within just a few minutes (especially in warm, dry weather). Some substrates such as limestone are less reactive. In these cases the effect may take some days to fully develop. The application should be continuous and uninterrupted so that no overlapping occurs. If doplets form on the surface they should be evenly disributed using a soft brush. It should be avoided to distribute a dried film with a brush.
